Cucumber - the most popular vegetable for greenhouse breeding. Polycarbonate is great for growing it, as it has the ability to retain heat and to transmit enough light. In a polycarbonate greenhouse, it is easier to create the necessary microclimate for cucumbers.

The advantages of the greenhouse

When complying with agrotechnics, growing cucumbers in a greenhouse has great advantages over planting vegetables in the ground. Experienced gardeners prefer plant cucumbers in a polycarbonate greenhouse for several reasons:

  1. It is here that you can create a more favorable microclimate for the growth of cucumbers. The integral design does not contain cracks, which preserves the plants during the period of spring night frosts and unfavorable summer weather. Airing, if necessary, by using the vents provided for in the design of the greenhouse.
  2. There is no need to shoot polycarbonate for the winter, this allows in the early spring to produce planting work in the greenhouse and get an early harvest.
  3. Yield increase.
  4. Prolongation of fruiting.
  5. The possibility of planting in central Russia varieties zoned for the south.
  6. High yields allow not only to grow vegetables for personal farming, but also to do if you want a profitable business.

The only drawback of growing cucumbers in the greenhouse is the high cost of the material and the cost of installing the greenhouse, which, however, is more than worthwhile if the harvest is not only for themselves, but also for sale.

Features of the choice of seeds

For greenhouse cultivation is very important to choose the right cucumber varieties. To obtain a high, stable yield, several factors must be taken into account:

  1. Shade tolerance. If the greenhouse is not equipped with additional lighting, it is necessary to choose varieties that easily adapt to the lack of light.
  2. Cold resistance. If additional heating in the greenhouse is not planned, it is necessary to choose cold-resistant varieties or plant cucumbers seedlings at a later date.
  3. Pollination method. Ideal conditions for natural pollination cannot be created in a greenhouse; therefore, it is recommended to choose self-pollinating plants. These varieties have a drawback - they are more difficult to take root, less resistant to temperature extremes.
  4. The method of processing the crop. For canning, you should choose varieties with a thin peel. Salads are more suitable for cucumbers with a thick skin, which have a “rich” cucumber smell and taste. But most often cucumbers are grown for fresh consumption, salads, and for harvesting for the winter. Therefore, it is more expedient to choose universal varieties.

How to grow cucumbers in a greenhouse

High yields are directly dependent from the conditions that they will create gardeners:

  • carefully prepare the greenhouse, soil,
  • make no mistake with the choice of seeds,
  • to decide on the landing time,
  • create favorable conditions during the growth of cucumbers.

Greenhouse preparation

To plant a cucumber greenhouse must be prepared thoroughly.. This vegetable is susceptible to diseases and is often affected by pests. Often, experienced gardeners start preparing a greenhouse for the next season in the autumn, but you can also prepare it in spring (in March).

  • If cucumbers were already growing in the greenhouse, it is necessary to completely replace the soil. Second-year cultivation on the same soil is not recommended.
  • In the autumn after harvesting, you can light smoke bombs that will destroy all pests. It is necessary to wash the greenhouse well: if there were no pests in it and the crop was not affected by diseases, it is enough to wash all internal structures with tar or household soap.
  • For plant diseases, treatment with soap is not enough. Disinfectants must be used. Greenhouse can be treated with bleach inside. If last year's cucumbers were affected by rot, it is necessary to process all the structural elements with copper sulphate.
  • Lime can be used for disinfection. Everything that is in direct contact with the soil should be whitened, and the frame should be carefully treated.

After washing the greenhouse, it must be processed with smoke bombs, guided by the instruction to the preparation. During the processing of smoke can not open the greenhouse.

Seed treatment

No matter what type of cucumber planting will be chosen, it is necessary carefully prepare the seeds. In order to prevent future plant contamination, seeds are soaked in a solution of potassium permanganate for 15 minutes. Empty seeds float to the surface, they must be removed. Then they are thoroughly rinsed with plenty of water. Seeds of hybrids, which are on sale, have already been treated with a special compound, so additional processing is not required.

Not all varieties are suitable for growth in closed ground. Some require pollination by insects, in a greenhouse they will have to pollinate on their own. Best for greenhouse cultivation suitable hybrid self-pollinating varieties. These varieties are high-yielding; they are grafted in advance against many diseases. Pre-treatment with disinfectants is not required. It is necessary to choose zoned varieties, especially for plants for northern latitudes.

Arrangement of beds

Cucumbers are demanding for highly fertile, loose soil. The soil, except for the ground, must contain vegetable humus and manure. Manure is especially needed if additional heating of the greenhouse is not expected. For more loose soil, you can also make peat with sawdust, straw. The soil is prepared in advance and entered into the greenhouse as a finished product. They form beds of at least 80 cm wide. The height should be 35 cm. Between the beds, a passage of 70 cm is left.

A horizontal wire trellis is laid in the greenhouse, which is necessary for tying the cucumber strings. It is located at a height of 2 m. Tying up lashes is necessary, it will save them from fungal diseases.

After the soil has been prepared, the beds are watered and covered with a film in order to maintain heat and humidity.

In areas with a harsh climate, additional seedling shelter is required. On the beds set the arc, cover them with a film. The temperature in this additional greenhouse doubles. Manure introduced into the soil from below heats the garden bed.

There are two types of planting cucumbers in the greenhouse:

  1. Seeds. Before sowing, seeds are soaked, empty - removed. Then they must be germinated by placing in a warm place. After the appearance of small sprouts, cucumbers are planted in pre-prepared holes of several seeds to a depth of 3 cm for loose soil and less than 2 cm for heavy soil.
  2. Seedling method. It is used where spring night frosts can kill a young plant. This method speeds up fruiting by about 2 weeks. Seeds are planted in peat pots or paper cups, which can be made independently. When the seedlings will have 4–5 true leaves, they will be planted in a permanent place.

Planting schemes

High yield of cucumbers depends not only on the choice of soil and care, but also the correct planting scheme. For planting in the greenhouse apply the following schemes:

  1. Single line. This method is planted high-yielding varieties with large leaves. Despite the fact that with a single-line planting, you can make narrower beds, there will not be significant savings in area. To prevent large bushes from closing, wide aisles are made in the greenhouse.
  2. Two-line. For compact bushes with medium-sized leaves, a two-line planting method is suitable. Plants are located one against the other.
  3. Chess In order that bushes are better shined with the sun, apply landing in a chessboard order. For this you can use any variety.

Cucumber care

Greenhouse crops require special attention.. From the beginning of planting and the appearance of the first flowers on cucumbers, cares of gardeners are added: the formation of bushes, timely watering and regular feeding. It is necessary to constantly monitor the air temperature, monitor the health of vegetables, destroy pests.

The formation of the cucumber lash is of great importance. If it is not produced, the greenhouse will look like impassable thickets. And the growth of numerous side shoots will sharply reduce the yield and provoke the appearance of diseases.

On the 15th day after planting the plant must be tied up. For this, synthetic twine is used. Once a week it is necessary to twist the stem around it, it should be done in one direction.

Formation scheme:

  1. The cucumber is formed into one stem, the twine around it is tied freely, and the thickness of the stem increases with the growth of the plant.
  2. All lower flowers are removed to the fourth true leaves. Lower shoots restrain the growth of cucumbers.
  3. 5–6 lateral shoots are left 20 cm long, the tops pinch.
  4. With 7 shoots, the side shoots 30 cm long are left, the tip is removed.
  5. Next to the trellis leave shoots up to 50 cm.
  6. The main trunk, which reached the trellis, spreads over it 2 times.

It is important to maintain optimum moisture in the greenhouse. For the cultivation of cucumbers, it must be high, drafts are unacceptable. Favorable temperature for the growth of cucumbers - from 25 ° C.

Watering should be done twice a week., but it is better to focus on the state of the soil. On sunny, hot days it is necessary to water more often.

High yields can be obtained by regularly applying organic fertilizer (manure). The first top dressing to make the beginning of flowering, then fertilize the soil every 10 days.

After each watering, it is necessary to loosen the ground, it removes the crust from the soil surface, and the roots are saturated with oxygen.

Pests and diseases

Improperly prepared soil, diseased seedlings, low temperatures, irrigation with cold water can provoke the development of diseases and the destruction of cucumbers by pests.

Pest and disease control methods:

  1. Gourd aphid. Appears in the second half of summer. The insect is so aggressive that it destroys the plant in a few days. The fight against it must begin at the first detection of a pest, until the plant louse has spread to the entire crop. We must first weed the weeds, then spray the plants with infusion of red pepper or a mixture of water and tobacco. For one square meter used 2 liters of infusion.
  2. Hothouse whitefly. Sucking the juice from the leaves, the whitefly becomes the reason that they turn yellow and dry out. The fight is the timely removal of weeds. You can put glue traps in the greenhouse.
  3. Mealy dew. The most common disease in the cultivation of cucumbers. The appearance on the leaves of white mealy plaque leads to the fact that the whole plant becomes infected and dies. At the first sign of cucumber sprayed with infusion of urea or mullein.
  4. Gray rot. Often affects plants in greenhouses. The disease is provoked by low air temperature, watering with cold water, and lack of ventilation. You must regularly inspect all parts of the plant. With a large lesion, the plant is removed. With a strong infection, the affected parts are cut out and treated with a solution of potassium permanganate.

Polycarbonate greenhouse allows you to get a good crop of cucumbers in climatic conditions where a different method of cultivation may not give positive results. Adverse weather conditions also will not interfere, if on your site you put a small greenhouse.

Diseases: description and control measures

Occurring diseases in the greenhouse, when growing cucumbers, are not limited to one name. Tell about most common. These include:

  • white and gray rot,
  • root rot,
  • dew: false and mealy,
  • brown spot (olive),
  • leaf mold (black).

Let us consider the disease of cucumbers in the greenhouse and their treatment with illustrative examples in the photo.

Causative agent plant diseases is a fungus. A sign of defeat is a fluffy patina of white in all parts of the plant, from roots and lashes, to leaves and fruits. Secreted by fungus substances not only destroy the plants, but also stored in the ground very long time.

Over time, the diseased plant tissues rot completely. To fight this disease is difficult, but quite possible. The control measures are the removal of all remnants of the affected plant, old fruits and leaves. Full soil replacement is desirable. at the site of planting cucumbers.


Useful information about white rot on cucumbers in the video:

A sign of defeat gray rot is the appearance of gray, slippery spots on the fruit. Then the infection spreads throughout the plant. Fruits, ovaries, flowers are most affected.. Countermeasures are the same with those with white rot.

Only the need for pollination in the initial stages of the disease with a mixture of copper sulfate (one teaspoon) with a glass of wood ash is added. Spraying will help, with strict compliance with the instructions, the drug type "Barrier". The drug is not dangerous for people and animals.

Important: even in the absence of fungal infections, a change of soil in the greenhouse every two years is recommended. Replace the surface layer of soil (about 20 centimeters) with a mixture of earth, peat, sand. Important to ensure good drainage and soil fertility.

Very often, this disease manifests itself when planting seedlings of cucumbers in the greenhouse. Occurs due to deep landing, may occur when conducting additional hilling plant stalks. The disease develops very quickly, especially if the seedlings were planted on the soil where cucumbers used to grow. To provoke a disease can watering with cold water or a sharp decrease in the temperature of the soil.

Disease indicator there are spots on the leaves, which are especially visible after a prolonged bad weather. A sign is also the cracking and well-marked yellow color of the stems. Cracking and discoloration clearly seen, if you otgresti land from the stem in the holes.

Damaged tissue can be clearly seen when raking the ground from the stem of the plant. Places of damage can be powdered with crushed chalk or coal, wood ash. After this is required dry spots. During the next watering, do not allow the stalks to fall asleep with earth, water only the soil in the hole, preventing moisture from entering the affected stalks.

Completely dead stems are cleaned with a clod of earth. Pour the remaining well with an aqueous solution of copper sulphate, prepared in the following proportion: for 5 liters of water, 20 grams of copper sulphate. Dead plant burn.

Useful information about root rot on cucumbers in the video:

Affected Cucumber Stalks covered with white bloom. The lesion is caused by a fungus. The first leaves are affected. Further, the disease spreads to the stems of plants. The next stage of the disease is drying and dying off of leaves and stems. An excellent preparation for the fight is "Topaz". The drug is available in ampoules, the contents of which is dissolved in eight liters of water.

The resulting solution is sprayed affected plants. Treatment with a solution can be carried out not only in the manifestation of signs of disease, but also for the purpose of prevention.

Spraying solution is prepared at the rate of - three caps of the drug dissolve in a liter of water.

Attention! For the prevention of diseases, especially when large areas of treatment use biologics. Such as Alirin-B, Gamair, Gliokladin, Trihotsin. Remember to strictly follow the instructions for use.

Downy mildew

The causative agent of downy mildew remains in the ground for a long time, can manifest itself in 5-7 years after the first illness. A sign of infection is the appearance of burn-like spots on the leaves. In the future, the leaves become brown. Drying of the affected leaves very fast, no longer than 2-3 days.

To provoke an infection can watering with cold water or a sharp difference in day and night temperatures, high humidity in the greenhouse at night. Struggle measures serves to stop watering and making dressings. Ventilate the greenhouse to reduce humidity.


Useful information of false flour mildew on cucumbers in the video:

Spot spot brown (olive)

Most often defeat manifested on the fruits of plants. Signs are the appearance of defects of brown color, from which is the flow of fluid. If no measures are taken to protect against the causative agent, all plants in a greenhouse may die within a week.

High humidity, drafts, excessive watering, and strong temperature differences during the day can provoke infection. To combat the disease night drafts should be avoided, for 5-7 days, stop watering, in the daytime, the warm time of the day to prevent the appearance of condensation, to air the greenhouse.

Leaf Mold (Black)

Defeat of plants causes funguslocated on the inner surface of the coating and in the soil of the greenhouse. The first most often affected leaves. Further, the disease spreads to all parts of the plant that are above ground level.

Spots appear on the leaves, gradually merging into one. Affected leaves dry out, subsequently covered with black bloomvery similar to the web. The fight measures are disinfection of the greenhouse inside, replacement of soil on cucumber ridges, seed dressing or the use of disease resistant varieties.

Gourd Aphid

Сморщивание и скручивание листьев Cucumber most often say about the defeat of melon aphids. On the leaves appear yellow spots, the sheet is folded. When viewed on the bottom of the sheet you will see aphid larvae of various colors. Having chosen the plant, aphid sucking juicesby slowing its growth and development.

The development of numbers is very fast and the aphid spreads over all planted plants. If you find an aphid on cucumbers in a greenhouse, the control measures are the following - in order to protect planting, it is advised to use an infusion of onion peel that will destroy the aphid in your greenhouse.

Spider mite

Defeat of spider mite Leaves and stalks dry out.and subsequently the complete destruction of the plant. Determination of mite damage can be on the web on the leaves and stalks of cucumbers. When spider mite is detected need to quickly process planting in the greenhouse. Spider mite on cucumbers in the greenhouse, without the measures taken to destroy it, can lead to the loss of all planted cucumbers.

The removal of completely damaged plants is most effective, with their subsequent burning. If a single plant is damaged, it is necessary to cover it with a film or cloth by placing inside a container of turpentine.

Instead of turpentine you can put chopped garlic next to it. Smell will destroy the aphid colony on the plant. Processing must be carried out repeatedly, maintaining a break of 2-3 days.

Timely damage to the hives in your greenhouse with fungus or pests, with timely processing will help save the plants.

And saving planting, you will not be left without a crop of cucumbers.

Pros and cons of growing cucumbers in the greenhouse

Greenhouse conditions for growing cucumbers have their own advantages and disadvantages. The advantages of greenhouse cultivation of culture include:

  • the possibility of obtaining a crop of varieties of long lettuce cucumbers with a thin peel (such plants are usually not adapted for cultivation in open ground — thin skin is affected by diseases),
  • early harvest
  • cucumbers tied to a trellis have the same color of fruits on all sides (in the open ground, in the places of contact with the ground, the peel is colored yellow).

Among the disadvantages of greenhouse cultivation are:

  • it is necessary to constantly maintain the quality of the soil, nutrients are quickly depleted in its limited quantity, therefore, the plant feedings in greenhouses are more carefully monitored
  • the need for annual crop rotation causes gardeners to sow the greenhouse after harvesting cucumbers with intermediate crops. Otherwise, in order to prevent the development of diseases and pests, the soil will have to be replaced,
  • it may be difficult to pollinate the flowers, but if you plant self-pollinated hybrids, this disadvantage will disappear.

All the disadvantages will be quite insignificant with the knowledge of the agrotechnology of growing cucumbers in greenhouse conditions.

When to plant cucumbers for seedlings for the greenhouse

The optimal age of cucumber seedlings for planting in the greenhouse is 25 ... 30 days. Overgrown and underdeveloped specimens will root poorly. In addition, when choosing the dates of sowing for seedlings should take into account the climatic conditions of the region and the recommended dates of planting at a permanent place. For example, in the conditions of the Moscow region and the Central band, landing works in unheated structures start in mid-May. In the Urals and Siberia, as well as in the Leningrad region - at the end of May.

Taking into account all the nuances, it is easy to calculate the optimal time for sowing: from the date of planting in the greenhouse they count back 30 days (age of saplings) and several days before the emergence of shoots (if the seedlings were planted, they determine the optimal time for germination, but not sowing, dry seeds sprout in 4 …6 days).

Growing seedlings

The earliest crop of cucumbers can be obtained through seedlings, so many gardeners resort to this method. Personally grown seedlings are much cheaper than purchased ones, especially if they plan to plant a large greenhouse space. In addition, the gardener can be assured of compliance with the variety, while in the markets and exhibitions often slip fakes that are inconsistent with the declared grade.

Preparation of soil and tanks

Since the sprouts of the culture do not like transplantation and do not tolerate it well, it is better to plant the seeds immediately in separate containers. The best option is considered to be peat pots, which are buried in the ground along with seedlings when transplanting to a permanent place. They are filled with light nutrient primer, which you can buy in the store or cook yourself.

For example, mix in equal proportions peat, humus, rotted sawdust with sod land. It is not necessary to fill pots to the very top - when watering, water will flow out at the edges.

Preparation of planting material

Purchased cucumber seeds are usually already decontaminated and prepared, so they are sown dry. The planting material collected from own cucumbers must undergo a high-quality pre-sowing treatment, which consists of:

  • calibration, the purpose of which is the separation of empty seeds. For this, seeds fall asleep in 3% saline solution, wait 5 ... 10 minutes, those that come up, throw it away. The rest is dried and used when sowing
  • treatment (disinfection), which is carried out in any convenient way - by soaking in a solution of potassium permanganate (20 ... 30 min) or a special preparation (1 ... 2 h) or by heating at a temperature of +40 0 С (3 days) or +80 0 С (1 day ),
  • quenching, as cold treatment significantly increases the cold tolerance and yield of future seedlings. Seeds are placed in wet gauze and refrigerated for 2 days.

Sprouting seeds is a great way to save space and get early sprouts. Seeds are placed in wet toilet paper (gauze and cotton wool are not used for this purpose, as tenacious roots break when seeds are removed from the material). At a temperature of ± 25 ... ± 28 0 С sprouts will appear in 1 ... 2 days.

The soil in the planting tanks pre-moisten and begin sowing. They are placed at a depth of 1.5 ... 2 cm flat, sprinkled on top of the soil. If the landing is made in separate cups, place in each of them no more than 2 pieces. If in a common container, the distance between the planting lines is 2 cm, and between the seeds in a row - 1 cm.

The top layer of the substrate is slightly moistened, the container is tightened with plastic wrap and removed in a dark warm place. You must regularly check for seedlings. As soon as the first shoots appear, the containers are placed on a well-lit window sill.

Care of seedlings before planting is in watering, feeding, if necessary - the organization of additional lighting.

Feed the seedlings can be started 2 weeks after the emergence of sprouts. Here they use water-soluble complex fertilizers, which are diluted in accordance with the instructions on the back of the package.

Approximately 3 weeks after germination, seedlings are ready to be transplanted to the greenhouse. By this time, each of them should be about 30 cm high and have 3 ... 4 true leaves.

When to plant cucumbers in the greenhouse, the timing

Planting work in unheated polycarbonate greenhouses is carried out already in mid-late May. A more accurate date should be selected according to weather reports in the region. The air temperature in the greenhouse should be within + 16 ... + 18 0 С, while the radius of oscillation between night and day temperature should not exceed 6 0 С.

The soil, of course, must be warm enough, otherwise the young roots will freeze, and the plants will die due to the lack of nutrients from the soil.

Distance between cucumbers

Typically, in greenhouse conditions, cucumbers are grown according to a two-line ribbon scheme, which is the presence of one or several longitudinal beds, the distance between which is about 80 cm, and cucumber bushes are placed on each ridge in 2 rows.

How many pieces to plant in the greenhouse

In order not to grow too much or, on the contrary, too few seedlings, it is necessary to calculate the necessary number of root pieces before growing the seedlings. Of course, gardeners sow more seeds for seedlings, as some of them may die at the seedling stage, others - during transplantation. But you need to build on the calculated number.

In order to carry out the calculation, you need to know exactly what area will occupy cucumbers in the greenhouse, as well as the dimensions of the design itself. Greenhouses with a width of 3 m and a length of 5 m are most often found on the suburban areas. The width of one wide bed is about 1 m, so in such a greenhouse they organize 2 wide ridges with a hike in the middle.

Thus, the calculation is carried out: (5: 0.35) x4 = 56 - the length of the greenhouse is divided by the optimal distance between adjacent bushes and multiplied by the number of rows (in this case, 2 to 2 beds). Of course, gardeners rarely allocate all the space of a polycarbonate greenhouse as cucumbers, often tomatoes, eggplants, and peppers become their neighbors, but the calculation will still be similar to that indicated earlier.

Formation

  1. The lower ovaries of the cucumber develop very slowly and slow down the fruiting, therefore the lower sinuses blind, remove all flowers and lateral processes.
  2. In the lower part of the stem, all shoots are shortened (4 ... 6), leaving up to 2 ovaries on each.
  3. The shoots of the middle part of the stem are shortened above the second leaf.

All further shaping of the bush is reduced to the direction of long lashes inside the bush so that they do not grow into the passage area.

By feeding the cucumbers growing in greenhouse conditions, you need to be especially careful, as the lack of an element in the substrate will instantly affect the health of the plants. During the season, the bushes are fed no more than 5 times.

Cucumbers respond particularly well to fertilizing with organic matter containing a large amount of nitrogen. This group includes chicken manure, humus, mullein. All fertilizers are applied in a liquid form by irrigation. To prepare the solution make 150 g of organic matter in a bucket of water. The working fluid ferments for 2 days, after which it is enriched with mineral fertilizers (30 g of superphosphate).

An excess of fertilizers, as well as their lack, will negatively affect the condition and fruiting of the bushes, therefore fertilizing is carried out regularly and in a timely manner, observing the recommended frequency of fertilizer application.

Cucumbers are fed with nitrogen during active growth, potassium and phosphorus during flowering and growth of lashes, all three elements during fruiting.

Diseases and pests

Usually problems with growing cucumbers does not arise if the agricultural technology of planting and caring for the crop was observed. But even in this case, evil pests and diseases can appear and spoil the crop.

The most common pests of cucumbers in the greenhouse are the melon aphid and spider mite. Folk remedies with the use of deterrent solutions can only help with local and small areas affected by insects. Therefore, most often resort to chemical remedies and carefully spray them with a solution of each bush. The range of purchased funds against them is wide. You can use, for example, Fufanon, Fitoverm, Karbofos.

Diseases of cucumbers are divided into infectious and non-infectious. The first group includes root, stem, bacterial rot, fusarium, powdery mildew, and others. The second group includes diseases resulting from violations of the agrotechnology of cultivation of a crop, for example, an oversupply or lack of nutrients, moisture, etc. To cure such diseases can be a simple identification of symptoms and making or, conversely, limiting water and fertilizing.

The best varieties of cucumbers for the greenhouse

Gardeners very carefully select varieties of cucumbers for their greenhouses. It must meet several requirements:

  • high quality fruits
  • resistance to temperature changes
  • disease and pest resistance
  • high yields.

Below are the self-pollinated greenhouse cucumber hybrids that meet all these requirements.

Herman F1. Hybrid ripening, in which the fruits ripen in 45 days. Small, hilly green cucumbers are the best suited for salting and canning - they do not form internal voids, they do not have a bitter taste. Beam fruiting, in one node 4-6 Zelentsi are formed, about 9 cm long.

Zozulya F1. A reliable old well-known hybrid that gives cucumbers up to 22 cm long. The weight of one of them can reach 300 g. In the knot, 2 ... 3 greens are tied. Fruiting early, comes in 35 ... 40 days.

Chinese heat resistant F1. A long lettuce cucumber, fruits appear on day 54. The advantages of the variety are high yield and fruit length up to 50 cm. Zelentsy do not have internal voids. The skin is thin, covered with small tubercles.

Cucumbers in a polycarbonate greenhouse reveal their full potential with proper planting of high-quality and healthy seedlings and careful care throughout the season. For all the work of the bushes thank the high yield of fruits with excellent taste and commodity qualities.

The advantages of greenhouse growing vegetables

Cucumbers, undoubtedly, are one of the most common and favorite vegetables in gardeners. Along with the cultivation of this crop in the open ground, greenhouses are becoming more common. And this is not surprising. Observance of the correct agricultural technology gives a big plus to the greenhouse variant of growing cucumbers in front of the open ground.

The advantages of greenhouse cultivation:

  • yields from the same area are several times higher
  • the possibility of obtaining early harvest
  • the extension of the growth of this vegetable in the middle lane until the beginning of October,
  • the use of cucumber varieties zoned for the southern regions.

Applying the correct varieties of cucumbers and the technology of their cultivation in the greenhouse, special technical means to maintain the optimum temperature and humidity, it is possible to grow this vegetable throughout the year on the territory of the middle lane.

If desired, growing cucumbers in a greenhouse, gardeners can get crops for personal consumption, and engage in a fairly profitable home business.

The only drawbacks can be considered the financial costs of making or buying the greenhouse itself and investing large physical forces.

It is possible to grow cucumbers in a heated greenhouse all year round.

Autumn after harvest

In the autumn, when the crop of cucumbers is harvested, they inspect and repair the frame, change the damaged areas of the coating. The condition of the film or glazed coating is controlled by the entire winter season. Wooden parts are treated with a three-percent solution of copper sulphate (70 g per 10 liters of water). Metal parts of the frame are painted. Glasses are sprayed with formalin (2 g per 1 liter of water) 1 l per m 2. If operation is envisaged during the winter period, electric lighting fittings and technical means for heating are checked and adjusted.

Garbage, remnants of old plants are removed from the ground, and the upper layer (4-6 cm) of soil is changed, because this is where pests and diseases accumulate. Then the earth is disinfected with a solution of copper sulfate at the rate of 1 tbsp. l 10 liters of water. Consumption during processing - 10 liters per 20–25 m 2 of greenhouse area. Also for disinfection of the soil, you can use a mixture of potassium permanganate and lime: 6 g potassium permanganate per 15 liters of water and 20 g of lime per 6 liters of water. If it is impossible to prepare the greenhouse in the autumn, disinfection is carried out in the spring - dissolve 1 tablet of Intra-vir and 2 tablets of Oxyhoma in 10 liters of water. This amount is enough for 15–20 m 2.

Organic and mineral fertilizers are applied: 20–25 kg of fresh manure, 30–40 g of phosphate and potash fertilizers per square meter. In the case of increased acidity of the soil, add 200–500 g of lime per 1 m 2. Then they dig up the earth to a depth of 30–35 cm.

Spring before planting

In the spring, when the earth warms up sufficiently, an additional layer of film is placed on the film greenhouse to avoid damage to the cucumber plantings at low night temperatures.

They form beds of at least 1 m wide and 25–30 cm high, leaving 60–70 cm between them. In the absence of heating the greenhouse, fresh manure is laid on the beds before sowing seeds, a layer of fertile, loose earth is about 25 cm. all this ridge plentifully watered and sowed the seeds. Instead of manure, it is possible to fill in the ready compost (sawdust, decomposed peat, rotted straw and grass, etc.). Then the seeds are not sown, and planted already prepared seedlings. If the formation of high ridges is not provided, and the plants will be grown directly in the ground, then in this case, add a simple - 80 g or double - 40 g of superphosphate per square meter. m

A prerequisite is the presence of a horizontal trellis made of hard wire, located at a height of 2 meters above the beds, to which the cucumber sticks are tied. This prevents overheating of the bushes and the development of fungal diseases.

High beds retain heat well in the soil

Planting cucumbers in the greenhouse

Cucumbers are planted in a greenhouse by seedling or sowing seeds directly on the beds. From the chosen method depends on planting dates and the technology of soil preparation in the greenhouse. At the time of planting significantly affects the material of the greenhouse: film, glass or polycarbonate coating. It is also necessary to consider the methods of heating the greenhouse - biofuel or convector. В последнем случае огурцы можно выращивать в течение всего года.

General rules

Высаживая огурцы в теплицу, надо руководствоваться следующим:

  • при посадке семена должны быть предварительно проверены на качество и проращены ,
  • рассадный способ предпочтительней посадки семян в грунт. The exception is polycarbonate greenhouse,
  • seedlings should be 25 days old and have 3–4 true leaves,
  • on 1 square. m. planted no more than four plants,
  • Planted seedlings form vertically, tying it to the trellis,
  • earthen clod of seedlings should be 1–2 cm higher than the bed,
  • for better pollination, they plant cucumbers of different varieties nearby.

Seed planting

For sowing, they select large, full-grown seeds and check their quality - immerse them for 20–30 minutes in a 5% salt solution. Floated - empty, they are removed. Before sowing, seeds are soaked or germinated. Before soaking the seeds are suspended in a tissue bag, preferably over a battery for a day. Soaked in about 10-12 hours immediately before disembarking. The seeds germinate by wrapping them in a damp cloth and placing them in a warm place for 20–25 hours, while poor-quality seed is also rejected.

Seeds are planted in prepared wells of 3–3 seeds. The embedding depth depends on the composition of the soil: on loose - about 3 cm, on heavy less - 1–2 cm.

Applying a seedling method of cultivation, it is possible to accelerate the entry of cucumbers into fruiting by one and a half to two weeks, than when they are planted with seeds.

It is best to plant seeds for seedlings in cups of soft paper or peat pots. In this case, when planting in the ground will not damage the roots of plants. Land for seedlings can be purchased ready-made in a store or made home-made - from a mixture of 1 part of garden soil and 0.5 parts of sawdust and humus each. Before planting seeds, the soil in the pots should be shed with a weak solution of potassium permanganate. Seeds are planted to a depth of 1-2 cm and covered with glass or polyethylene to create a microclimate. The temperature in the room during seed germination must be maintained within 22–28 ° C, and after 5–7 days, when seedlings appear, reduce to 18–20 degrees. In order to prevent stretching, you need to install an additional seedling light.

When planting seedlings in the greenhouse, the soil temperature should be at least 16–18, and air - 20–22 degrees. In case overgrown plants are planted, they are positioned obliquely in the landing pits. Important: in the first days after disembarkation, seedlings are watered abundantly and shaded from the sun.

The seedling in peat pots has three leaves and is ready for planting in the greenhouse

Landing dates

Cucumbers on the time of ripening are divided into early, mid-ripening and late varieties. Therefore, we can give the following general recommendations on the timing of sowing seeds for seedlings.

  • Early varieties - from March 15 to April 20. They have the highest rate of maturation.
  • Mid-season varieties - from early to mid-May.
  • Late varieties - from the end of August. Planted hybrid varieties of cucumbers. Their ripening period is 60 days, so the harvest can be harvested until November.

When growing cucumbers in a seedless way, the planting time is determined according to the maturation of the soil and the stable air temperature. The earth should warm up to 16 degrees, and the air - up to 20 o C.

Planting schemes

Successful cultivation and sustainable yields, other than soil and care, are influenced by the right choice of planting pattern. The state and development of cucumbers depends on it. In greenhouses, one- and two-row and staggered plantations should be used.

The most fruitful and large-leaved varieties of cucumbers are planted in one line (row). The beds are long and narrow. The disadvantage of this method is that there is no economy in the area of ​​growing plants due to the wide aisles between the rows.

In the two-row scheme, cucumbers are arranged in two rows, one bush is opposite the other. This scheme is suitable for plants with small leaves.

In order to improve the illumination, plants can be planted in a staggered manner, the parameters of the beds are similar to the two-row scheme. A shrub planted in the second row “supports” the distance between plants in the first half planted in the first row. This scheme involves the cultivation of cucumbers with large leaves and long fruits.

Table: intervals when planting cucumbers

When growing cucumbers use different schemes of their plantings

Planting cucumbers with seeds in the soil is recommended to thicken the planting with the possibility of not germination of the seeds. Then you can thin out the seedlings by transplanting “extra” bushes to another place.

Features of planting and caring for cucumbers in greenhouses made of polycarbonate: how to grow a rich harvest

Using greenhouse polycarbonate greenhouses, in March you can begin to grow cucumbers. The loss of heat in them is less than in greenhouses made of film and it is easier to create additional heating. The advantage is that in polycarbonate greenhouses the seeds can be sown directly on the beds with biofuels - this reduces the cost of preparing seedlings. And the plants themselves will be spared from temperature adaptation - in the process of growing, they will get used to low temperatures. Using seeds of early varieties, planting seeds in the ground begin in early March. After 21 days, sprouted sprouts swoop down and sit on a permanent place of growth.

Video: The main points of planting cucumbers in the greenhouse

Cucumbers are a very moisture-loving crop. It is necessary to properly organize the process of watering plants in the greenhouse. Watering, it is important not to overdo it - excessive watering leads to diseases (decay) of plants.

After planting, before the flowering begins, cucumbers are watered moderately - per 1 sq. M. m poured 4-5 liters of water. Such a rate of irrigation will prevent the growth of leaf mass of plants and contribute to the active formation of ovaries.

During the formation of ovaries, during all active fruiting and after harvest, cucumbers require the most water. Therefore, from the beginning of flowering and until the end of the growing season, the irrigation rate is increased to 9–12 liters per 1 m 2.

The frequency of irrigation depends on the state of the ambient temperature. In hot weather, it is watered daily, with moderate heat or on cloudy days, 1–2 waterings per week are sufficient. During the abundant fruiting watered every other day.

Watering should be guided by the following rules:

  • it is necessary to control the condition of the soil under the bushes: it should be moderately wet, but not too wet,
  • when planting leaves of a plant, it is necessary to water urgently,
  • at the beginning of fruiting, it is possible to apply drying of the soil in order to accelerate the development of the ovaries,
  • Do not allow changes in soil moisture,
  • water should be watered at least 18–20 o C,
  • the most favorable irrigation time is in the evening, after sunset,
  • after watering, be sure to break through the ground.

Advantages of drip irrigation in greenhouses

Various types of equipment are used for irrigation: watering cans, buckets, hoses, etc. There are also automatic irrigation systems:

  • sprinkling,
  • aerosol avtopoliv,
  • drip irrigation system.

The drip irrigation system is the most convenient and rational for irrigating cucumbers in the greenhouse. Consider the advantages of this method:

  • water comes directly under the root of each plant,
  • automation of the process, which allows gardeners to visit their garden and summer cottages less often,
  • there is no danger of soil erosion,
  • the exact dosage of the feed, and hence the saving of water,
  • at the same time with irrigation, plants can be fed,
  • easy maintenance
  • reduced physical costs
  • ultimately - increasing yields.

The main disadvantage of drip irrigation is the high price of standard irrigation equipment offered by manufacturers. But gardeners invented many homemade devices for drip irrigation. And anyone who can hold a tool in their hands can build such a system in their greenhouse.

Drip irrigation allows you to deliver water to each plant directly under the root

During the growing season cucumbers must be given top dressing. Different types and norms of organic and mineral fertilizers are used in different growing cycles. During the season, the plants are fed at least four times.

Benefits of indoor cultivation

Every year the popularity of growing cucumbers in greenhouses is constantly increasing, which is explained by the opportunity to get a great harvest and a significant simplification of planting care.

The advantages of greenhouse cultivation include the following:

  • Getting the most early harvest.
  • Improved yields.
  • Plants can bear fruit until the beginning of October.
  • The possibility of using varieties zoned for the southern regions.

Previously, most gardeners used home-made greenhouses covered with film and similar materials. Today the most popular hotbeds made of polycarbonate, which simultaneously combine ease of use, versatility, ease of installation and durability and have an affordable price.

Selection and preparation of the greenhouse

The size and shape of the greenhouse for growing cucumbers can vary significantly. Preference should be given to greenhouses with a height of more than 2 meters, which will make it easy to tie up large-sized whips of cucumbers and improves the yield indicators of the beds. You can use as small in size greenhouses with dimensions of 2 to 4 meters, and full-sized structures, the total area of ​​which is 15−20 square meters.

To ensure the highest possible yield, cucumbers in the greenhouse are planted in fertile, properly prepared soil, which will be the key to obtaining a good harvest of tasty and healthy vegetables. Soil preparation begins in the autumn, when the ground in the greenhouse is dug up, the roots, weeds and weeds are removed from the ground. The soil is disinfected, for which you can use a chlorine solution, 400 grams of powder which is dissolved in a bucket of water and insist 3 hours. The resulting chlorine solution shed the earth, frame and other elements of the greenhouse. Also for disinfection, you can use a solution of potassium permanganate.

The following fertilizers are applied to the soil in the fall per square meter of bed:

  • Phosphorus - 30−40
  • Potassium compounds - 40 g.
  • Manure - 25 kg.

Fresh manure can be applied to the soil if the soil preparation is done in the fall. If such work is carried out in the spring before planting cucumbers in a greenhouse, then humus or peat should be used.

Immediately before planting seeds or seedlings in the soil, the following dressings are additionally applied per square meter of bed:

  • A mixture of Exo - 2 kg.
  • Superphosphate - two tablespoons.
  • Wood ash - two tablespoons.

Fertilizer should be distributed evenly over the surface of the bed, after which the feed into the ground should be shovel or raked to a depth of no more than 10 centimeters. Experienced gardeners recommend adding two or three buckets of sawdust to the soil, which will be an excellent baking powder, improve the structure of the soil, and have a positive effect on yield indicators.

The beds in the greenhouse can be made at the same level with the soil, as well as high and warm, when wooden sides are used additionally 40–50 centimeters high. Such warm beds are often used by experienced gardeners, which allows them to get more yield, and the planted seedlings grow better and begin to bear fruit faster. When industrial cultivation of cucumbers in the greenhouse is also practiced planting seedlings in racks with small capacities for the soil, which allows maximum efficiency to use the available area in the greenhouse.

Planting seeds and seedlings

Cucumbers in the greenhouse can be planted with seeds and seedlings grown at home. Seed cucumbers in greenhouses planted in late March and early April. Ideally, it is necessary to provide additional lighting in the greenhouse, extending daylight hours to 14 hours per day. This will allow you to grow strong plants that later will be great to bear fruit.

Seedlings in unheated greenhouses planted in early May. The soil by this time should warm up to a temperature of 15 degrees. The seedlings are planted at home about a month before it is transferred to the greenhouse. It should not be allowed to overgrow the seedlings when it has four or five full-fledged leaves and a large root system, since later such plants do not tolerate the transplant and are sick for a long time.

Cucumber seedlings in a greenhouse can be planted in two ways:

With a parallel two-row planting scheme, the row row distance is about 60 centimeters, and in a row the distance between each bush is 25 centimeters. Every four rows must be done meter passage, which will significantly simplify the care of plantings.

With a chessboard landing pattern, the distance between plants in the same row is 50 centimeters, and the row distance is 75 centimeters. Between the two rows of ribbons perform a passage with a width of 90−100 centimeters.

Such planting schemes will allow using the greenhouse area with maximum efficiency, simplify planting care and prevent plant thickening, which can lead to a number of infectious and fungal diseases.

The following fertilizers should be applied to the bottom of each pit when planting seedlings:

  • Potassium salt - 10 grams.
  • Superphosphate - 10 grams.
  • Peat, compost or humus - 300 grams.

Immediately after planting, the beds are plentifully watered with warm settled water per 1 cucumber vine per liter of water. Also, it will be useful to further mulch the planting, which will exclude the freezing of the root system and help the gardener to retain moisture in the soil, preventing the soil from drying out.

Cucumber Care Basics

Ensuring proper care will be a guarantee of a good harvest in the garden. Cucumber is an undemanding culture, however, a gardener will still need to pay due attention to proper plant care, including the following work:

  • Correctly form a cucumber vine.
  • Regularly perform dressing beds.
  • Provide high-quality and timely pollination of ovaries.
  • To air the greenhouse.
  • Ensure timely regular watering.

Such care is not particularly difficult, so even beginning gardeners can handle it. But if the plants are not provided with the appropriate conditions, the growth slows down significantly, and the fruiting practically stops.

Feeding culture

During the growing season, at least three additional feedings of cucumbers should be performed, which will allow the growing and fruiting plants to provide all the necessary trace elements. The first feeding is done a few weeks after planting the seedlings. In 10 liters of water should be dissolved in 1 teaspoon of superphosphate, urea and potassium. The second feeding is done by a humate, one tablespoon of which is dissolved in a bucket of water. The third dressing is carried out directly during the period of active fruiting, when gardeners fertilize plants with a mixture of liquid mullein.

Pollination of peduncles

Pollination of peduncles in the greenhouse can be done both by insects and by hand with a brush. In the warm season, gardeners leave the greenhouse for airing, which allows insects to fly into the greenhouse and pollinate the plants. If such work is done manually, it is necessary to use thin brushes and act as carefully as possible.

Novice gardeners are recommended to plant self-pollinated cucumber varieties in the greenhouse, which will relieve them from the need to properly pollinate the planting, while ensuring the highest possible yield of cucumber vine.

Airing and watering

The greenhouse is regularly aired in the summer, for which a window is left open for a couple of hours or the roof is raised. In summer, in the heat, the vents for airing can be left open all day, ensuring the optimum temperature in the greenhouse at 18-30 degrees.

Watering plants in the greenhouse is carried out on a regular basis. Ideally, such work should be carried out twice a week. When watering is required to act carefully, avoiding the ingress of water on the leaves. For irrigation of landings, warm distilled water is used, which is previously maintained in tanks or barrels. Abundant and regular watering of cucumbers in greenhouses has a positive effect on yields and taste characteristics of ripened fruits.

Diseases and pests

Growing cucumbers in a polycarbonate greenhouse, a grower can face a disease like powdery, false dew. This disease manifests itself in the form of green oily spots on the leaves and shoots. Fighting powdery mildew must be sprayed with fungicides, and prevention will be the proper care of plantings.

Of the pest insects, the aphid, which likes to settle on the bottom large-sized leaves of a cucumber, causes the greatest problems. To combat aphids, it is recommended to treat the plants with a solution of bitter pepper, for the preparation of which it is necessary to dissolve 2 grams of black bitter pepper in 2 liters of water. Also, a whitefly butterfly can deliver certain difficulties, the caterpillars of which like to eat the tender young leaves of cucumber. You can get rid of the whitefly by manually collecting the caterpillars, in addition gardeners wrap gauze windows, preventing the butterfly from entering the greenhouse.

Выращивание огурцов в поликарбонатной теплице не представляет особой сложности, при этом садовод имеет возможность получить на приусадебном участке отличный урожай. It is only necessary to properly prepare the soil, make the appropriate fertilizers, use high-quality planting material, and in the subsequent gardener will need to regularly apply fertilizer, perform timely watering, properly form and tie up the cucumber vine. All this will be the key to getting a good harvest of tasty and healthy vegetables in the country.

Cucumbers in the greenhouse: agricultural technology, care, disease control, selection of varieties

. Such diseases of cucumbers in the greenhouse arise from the frequent use of the same soil, as well as from the decrease in soil temperature. Often, cucumbers in the greenhouse rot and because of irrigation with cold water, which is unacceptable. The disease is manifested by withering cucumber leaf. You can confirm it by simply paying attention to the state of the root stem: the stem affected by root rot turns yellow and cracks. To keep your plants healthy, try to maintain the necessary soil temperature in the greenhouse, arrange watering only with warm water and do not spud the plant. If the disease still overcame cucumbers, then prepare the following medicine: with 500 ml of water, take 1 teaspoon of copper oxychloride or copper sulphate, add 3 tablespoons of lime-fluff or chalk and mix well. After that, gently remove the ground at the bottom of the stem, from the roots and above, 15 centimeters, and moisten this part well with a solution with a brush. It is also possible to powder the sore spots of the cucumber with chalk, ash, or crushed coal, that is, dry well.

Cucumbers: basic information

  • Before flowering, cucumbers should be watered moderately, but do not forget to increase the watering of cucumbers in the greenhouse since the first ovaries.It is necessary to water them abundantly, with water at room temperature
  • The appearance of deformed fruits and falling leaves are caused by a lack of potassium. If there is a shortage of magnesium, the leaf turns yellow, and the veins remain green.The greenhouse must be placed in such a place that it is not affected by the north and north-east winds, it is also necessary to build a fence. Desirable
  • Watering the plants.Seeds prepared by summer residents on their own from ripe fruit do not guarantee even average indicators. Seeds should be seasoned for at least three years, so it is best to buy them in specialized stores and seed centers.
  • Quite often, cucumbers in the greenhouse turn yellow because of bacteriosis caused by inappropriate conditions. It can be temperature fluctuations, and cold watering, and insufficient ventilation, and so on. But other reasons are also possible, for example, often the leaves of cucumbers in the greenhouse often turn yellow due to the insufficient number of elements necessary for growth. In this case, foliar dressings should be carried out, that is, spraying.. Aphids on cucumbers in the greenhouse greatly damages the leaves, flowers, shoots and ovaries. Appearing in the second half of the summer, it can quickly spread and attack all the plants in the greenhouse. Fighting aphids is necessary at the moment when she was first noticed. Initially, weeds should be removed, then the plants should be treated with an infusion of fresh red pepper, preferably a bitter variety — with a bucket of hot water, 200 g of tobacco dust and 30 g of pepper. The infusion cools down, and it is thoroughly mixed and filtered, after which one spoon of soap and 2-3 tablespoons of wood ash are added to the liquid. Spraying is carried out once a week, up to 2 liters of infusion per square meter is used.
  • It is advisable to grow cucumbers on a vertical trellis, whose height will reach 2 m, and use a pick. In hybrid plants pinch the main shoot. This should be done when the plant reaches the top of the trellis, above the second or third leaf after the last fruit. Acceleration of fruiting can provide a pinch of cucumbers over the fourth or fifth leaf.Categories: Cucumbers
  • Brown spotIt is worth making a small digression and about the garter cucumbers on the trellis. It is advisable to tie them with a double sliding knot - so the plant will not be damaged.
  • Especially when fruits appear. Cucumbers grown in greenhouses, usually harvested after 2 days.Insufficient amount of minerals in the ground leads to the fact that the growth of stems slows down, the flower develops poorly, the yield of cucumbers is significantly reduced.
  • That the soil in this place was fertile
  • Before you grow, and subsequently reap a decent harvest, you must observe the following:
  • You can check the seeds for germination by a calibration method - dilute salt (10 g per 200 ml of water) in a container with water and fill up the seeds. Viable will settle to the bottom, and unfit for germination will emerge. Many gardeners and specialists use treatment with an average solution of potassium permanganate for 20 minutes, followed by the obligatory washing of the seeds.

Tillage and greenhouses

Varietal cucumbers form upon reaching the phase of the sixth or eighth leaf. It should pinch all the shoots and flowers in the first few sinuses, at the very beginning of their formation. It is necessary to check the following 4-5 knots and be sure to pin them on one cucumber and one leaf. With this process you will be able to form the right fruit-bearing shrub, which will have sprouts of the second and third order.

The yield of cucumbers in the greenhouse depends only on you and on how well you can follow the conditions necessary for the proper development of the cucumber. The cultivator of the cultivation of cucumbers in greenhouse conditions is practically no different from the agricultural technology in relation to the open ground. There are only some features that we will definitely consider. So, the cultivation of cucumbers in the greenhouse, tillage, the basics of care, feeding and disease control. . The causative agents of the disease can live in the greenhouse itself, on plants and various weeds, to infect cucumbers from the soil. Favorable conditions are high humidity and low night temperatures. The disease manifests itself with brown wounds all over the fetus, in which fluid accumulates. Since the onset of the disease, the cucumber becomes unsuitable for consumption. To prevent the spread of the disease to other plants, it is required to stop watering for 4-6 days, to conduct airing in warm weather, and in cold weather, on the contrary, to close the greenhouse in order to raise the temperature. Plants should also be treated with a 1% solution of Bordeaux liquid or foundation with no more than 30 g per bucket of water. Spray cucumbers from a sprayer only, on a warm morning, up to 10-11 hours.

The technology of growing cucumbers in a greenhouse always implies the right temperature, which should not survive sharp fluctuations - this is very harmful for plants. An example would be the temperature fluctuation during the day and at night, about +12 degrees Celsius and +28 ° C, respectively, when the active growth of the leaves begins to the detriment of the normal development of the fruit.

In this case, large brown spots appear on the leaves, the stems rot, and the cucumbers themselves are covered with weeping brown spots with a fluffy gray bloom. This disease appears most often at nighttime low temperatures, irrigation with cold rainwater and poor ventilation.

Cucumber best absorbs liquid fertilizer, therefore

Humidity and watering

Also a negative impact and lowering the temperature of the soil, for example, to + 13-15 ° C, when the roots of cucumbers can not absorb water. At the moment, comes physiological dryness. This term means the presence of water in the soil, but the impossibility of its entry into the plant. Often this is the cause of the death or disease of plants.

If the disease is started, then many male flowers appear on the plants, and in the bosom one leaf can even up to 15 barren flowers, which rot and strike healthy stems in a couple of days.

All fertilizers must be diluted with water

In the autumn, it is necessary to prepare a place for the future greenhouse. It is necessary to disinfect the blue vitriol with the wooden parts of the greenhouse, the metal ones - it is necessary to paint it. Remove 3-4 cm of topsoil. Add special fertilizers to the soil, such as: unfermented dung of 20-25 kg per 1 square meter, lime 200 g, potash and phosphate fertilizers of 50 g. After that it is necessary to dig up the earth. If the land will be prepared in the spring, then The main rule is regularity; draining the soil will lead to yellowing of the leaves or even death of the plants.

The time for such processing will take about 18 hours, and as a result we get friendly shoots. Some experts recommend using plant growth stimulants for this purpose.

As you know, the yield of cucumbers in a greenhouse depends only on you and on how you can comply with the conditions necessary for the proper development of the cucumber. Planting cucumbers in the greenhouse, caring for cucumbers in the greenhouse, the agricultural technology itself and the growing processes are quite complicated, so it’s worth taking the responsibility with great responsibility.

It is worth making a small digression and about the garter cucumbers on the trellis. It is advisable to tie them with a double sliding knot - so the plant will not be damaged.

. Another disease that often spoils the nerves of summer residents. It appears on the stalks of cucumbers and in the axils of the leaves, in the form of gray spots. The development occurs when poor ventilation, heavy landing thickening, during cold weather and watering with cold water. You can fight the disease simply by trying to change the conditions described above, and also treat the plants with the following mixture - mix 1 cup of wood ash and 1 teaspoon of copper sulfate thoroughly and sprinkle the infected areas with it. If the disease cannot be stopped, damaged shoots should be cut and burned.

Watering plants should occur only with warm water, as cold water can cause various diseases of the root system.

To avoid this, it is important to avoid thickened sowing, and with an abundance of barren flowers after flowering to remove them. Sprinkle the affected areas with wood ash, well-ventilated plants and rarely watering. Such a mixture is also considered effective: 1 teaspoon of copper sulphate + 1 cup of wood ash. All you need to mix well and sprinkle on the sore spots of plants. But if the disease is still progressing, then the damaged shoots must be cut and burned.

. There are many mineral fertilizers that are sold in tablets. Including manure is diluted with water, allowed to stand for a couple of days and stirred from time to time. You can use manure from poultry, cows and other animals. 1 kg of bird droppings need to be diluted in 20 liters of water, other types of droppings can be diluted in the ratio of 1 kg of manure to 5 liters of water. It should be noted that in large greenhouses they do not fertilize plants with manure, because there may be contamination of the earth by the bacteria that are in it.

Special non-fat manure must be added to the ground

Also a negative impact and lowering the temperature of the soil, for example, to + 13-15 ° C, when the roots of cucumbers can not absorb water. At the moment, comes physiological dryness. This term means the presence of water in the soil, but the impossibility of its entry into the plant. Often this is the cause of the death or disease of plants.

Ovaries, Diseases, Pests, Mistakes, Spider mitesToday we know the best varieties of cucumbers for the greenhouse and their hybrids:


Humidity should be slightly elevated and stay at 75-90% (air) and 50-60% (soil). Sprinkling will help maintain this humidity, especially on hot summer days. Use for this process 4-5 liters of water per square meter of beds. Do not forget that the water should not be cold - its temperature should be approximately the same as the air temperature.

Question answer

That is why it is necessary to take care of the prevention of this disease in advance. And this is disinfection, respect for the optimum planting density and the cultivation of hybrids that are more resistant in this regard. Diseased plants need to be destroyed, and the rest tied up with new twine.

When planting cucumbers need to be watered only with warm water. In cold weather it is better to water in the morning on a sunny day. In the warm season it is necessary to water the plants 2 times a day or once in the evening and very plentiful, since cucumbers grow most of all at night. The earth needs to be loosened so that oxygen penetrates better to the roots and that they do not fester.

Early cucumbers in the greenhouse - for health and joy

It is advisable to tie cucumbers with a double sliding knot, so the plant will not be damaged.

One of the main factors of good growth of cucumbers is their watering and the installation of the correct humidity in the greenhouse. The technology of growing cucumbers in the greenhouse implies constantly correct temperature, which should not survive sharp fluctuations, it is very harmful for plants

This disease appears when cucumbers are grown from year to year on the same bed - the infection simply accumulates, and the plants are quickly affected when the temperature drops and cold watering occurs. It can go from flowers and weeds.

The main vegetable in the garden

It is necessary to open a greenhouse every day so that plants are enriched with oxygen

  • Pinching or removal of the lateral ovaries is used so that the first leaves of vegetable juices do not select most of the plant juices and to form a powerful vegetative mass of the plant as a whole. Although in relation to modern varieties of cucumbers, this action is not always necessary.
  • Preparation of optimal soil composition for seedlings:
  • A greenhouse of medium size in the summer cottage or backyard can provide a family with a crop for the whole year.
  • . Another disease that often spoils the nerves of summer residents. It appears on the stalks of cucumbers and in the axils of the leaves, in the form of gray spots. The development occurs when poor ventilation, heavy landing thickening, during cold weather and watering with cold water. You can fight the disease simply by trying to change the conditions described above, and also treat the plants with the following mixture - mix 1 cup of wood ash and 1 teaspoon of copper sulfate thoroughly and sprinkle the infected areas with it. If the disease cannot be stopped, damaged shoots should be cut and burned.

What cucumbers can be grown in greenhouses

Humidity should be slightly elevated and stay at 75-90% (air) and 50-60% (soil). Поддерживать подобную влажность поможет дождевание, особенно в жаркие дни лета. Используйте для этого процесса 4-5 л воды на каждый квадратный метр грядок. Не забывайте о том, что вода не должна быть холодной - ее температура должна примерно совпадать с температурой воздуха.​

​Род растения:​​В данном разделе нашей статьи мы хотим привести примеры часто задаваемых вопросов и ответов на них.​

Before flowering, cucumbers should be watered sparingly, but do not forget to increase the watering of cucumbers in the greenhouse from the moment of the first ovaries.

To cope with a powdery plaque, the leaves should be sprinkled with a solution of mullein at the very first signs of disease: 1 liter of liquid mullein + 1 table spoon of urea, everything is mixed and filtered, and cucumbers need to be treated in the morning in warm weather using a sprayer. There is another way: finely ground sulfur is poured into a bag of three-layer gauze, and all these plants are pollinated in sunny weather, at a temperature of 23-28 ° C. It is only when processing that you close all the doors and windows, and cover the cucumbers themselves in the open ground with a film for 2 hours. And, finally, cucumbers are saved from this misfortune by a weak solution of manganese potassium - 1.5 g per 10 liters of water.

  • . The land should be constantly wet, because cucumbers are very fond of water, they themselves are almost 90% water. You must wear a spray bottle on the watering can in order not to damage the plant through the ground, because the roots are very close to the surface. In order to increase the yield of cucumbers, you can sometimes dry the ground.
  • Sawdust trees.
  • It is very important with the growth of vertical shoots to properly tie them to the trellis, avoiding the formation of a massive hat at the top. Better escape down and send down.
  • Cucumbers prefer light soil types without the presence of clay, which will contribute to the retention of excess moisture,

And for this, it is necessary to properly organize the functioning of all greenhouse systems:
Growing cucumbers in a greenhouse in winter and summer is possible only if the necessary conditions are created. In addition, conditions need not only to be created, but also constantly maintained, as well as to choose for the greenhouse precisely those varieties of cucumbers that are focused on a good harvest and meet your personal requirements. Putting together all the components, you can get a harmonious picture and an excellent result.

If you notice withered leaves or a painful type of cucumber, then do not be lazy to water them. The best time for this is from 11 to 12 o'clock in the afternoon, as well as from 13 to 15 hours.

Seed preparation and seedling cultivation

Such information is difficult to find in the current materials of the network, which is why we have compiled this list:

Watering plants should occur only with warm water, as cold can cause various diseases of the root system. Also, do not water cucumbers at the very root - the plants do not like it. Arrange small grooves along the bushes and spill water over them.

High quality of seeds is a guarantee of high yield.

This disease affects the leaves. On their upper side, chlorotic spots appear, which soon turn into yellow angular, and then turn brown at all. At the same time on the underside of the leaves in places spots will become visible grayish-purple bloom. At first glance, it seems that these are traces of “acidic” rain, but in reality these are signs of a disease that arises from a sharp temperature drop or irrigation with cold rainwater.

Initially, when cucumbers give only the first fruits, they need to be collected in the morning. In the future, you need to collect a couple of times a day, as they grow very quickly. If you do not harvest in time, the overgrown fruits will help to reduce the total yield. It is also necessary to remove ugly and damaged ovaries in a timely manner.

The beds in the greenhouse make a height of 20 cm, seedlings are planted 30 cm apart. If you plant more densely, then the plant will get less light than it needs. At a height of 2 m, the rope is stretched over the rows so that the plants can trail.

Preparation of cucumber seedlings for growing in greenhouse conditions

In the case of a large branching bushes can, as advised by the instruction, use the method of drainage or the so-called "drying" of the soil, without pinching. As a result, the growth of green mass will stop, and all accumulated nutrients will pass to the fruits.

It is preferable to choose the soil composition in such proportions: sod land with humus in equal parts with the addition of up to 10% of the total, wood ash.

  • If necessary, provide heating of the greenhouse,

Feeding cucumbers in the greenhouse is obligatory, but should be carried out correctly. For example, in the first few weeks after cucumbers have risen, they do not consume a lot of nutrients. The active process of their absorption occurs only at the flowering and fruiting phases.

  • First of all, saving cucumbers, you need to stop watering and fertilizing at least for a week. Damaged plants should be sprayed with Topaz solution, breaking one ampoule into 10 liters of water, or with oxychoma, spreading 2 tablets into 10 liters of water. In this case, the temperature of both solutions should be within 22-24 ° C (at night 18-22 ° C).
  • The most dangerous disease in planting cucumbers is powdery mildew. The leaves of the plants are covered with a specific bloom, dry up and fall off. With this disease, the plant disappears completely. You can save the plant if

Cucumbers germinate in 5 days at a temperature in the greenhouse of 30 degrees, if the temperature is not higher than 12 degrees, the plants will not germinate. Most

Plant nutrition

Top dressings themselves are best done closer to the evening time. After fertilization, water the plants with a small amount of water. After that you can pour a little fertile soil under the plants.

When the plants die, or the last crop is harvested from the greenhouse, the beds should be treated with copper sulfate solution, taking 3 tablespoons per 10 liters of water. All plants will need to sprinkle abundantly, and after a day everything will be removed from the roots and burned.

Prevention and control of plant diseases and pests

To establish an irrigation system, preferably drip, as the cultivation of early cucumbers in the greenhouse requires a regular, but not abundant, but very metered water regime.

In this section of our article, we want to give examples of frequently asked questions and answers to them.

The main diseases of cucumbers

Watering plants should occur only with warm water, as cold can cause various diseases of the root system. Also, do not water cucumbers at the very root - the plants do not like it. Arrange small grooves along the bushes and spill water over them.

Experts recommend buying only seeds produced from good yields, processed and properly seasoned before planting. To do this, you can always contact the experts in this field, for example, people who have greenhouses for more than one year, or purchase cucumber seeds in specialized stores.

Organic feedings are well suited in certain proportions - bird droppings 1:15, slurry 1: 5, mullein 1: 8. Experts advise to combine fertilizers and combine organic with mineral fertilizers. Thus, you can also apply the following solutions to the soil, which you need to water cucumbers at the rate of 0.5 l per each bush: no more than 5 g of saltpeter, 5 g of potassium salt and 10 g of superphosphate per bucket of water.

This disease occurs frequently in greenhouses. I can be amazed as individual plants, and the whole culture. To deal with this problem, it is necessary to disinfect the greenhouse soil and seed treatment, and severely affected plants will have to be destroyed. The seeds must be processed with a biological preparation “Trikhodrmin” at the rate of 4 g per kilogram and put it in the peat-earthen pots and in the wells at planting.

Pest control parasites

False powdery disease manifests itself in the form of oily spots on the leaves. Then the leaves turn yellow and fall away. At the first signs of such a disease, it is necessary to stop feeding and adding the plant. Treat with a special solution that is used for mildews disease.

How to grow cucumbers in the greenhouse? Caring for cucumbers in the greenhouse is that it is necessary to form a bush, tie up, water, feed, pinch and pollinate, if necessary. Cucumber grows one stem. After about 5 days, you need to tie up the plant so that it does not spread on the ground and does not break. Branching is limited with the help of plucking: tearing off the upper part of the stem, when it outgrows the rope stretched over the rows.

Signs of powdery mildew are clearly visible on the leaves of plants - they acquire a characteristic deposit, and later turn yellow and dry up, the plant may die within a few days. As a rule, the disease is activated with the onset of hot weather.

Greenhouse location

This disease begins to spread in cucumbers when irrigated with cold water - for example, when using the sprinkling method. And also with a draft that always weakens the plants. The cucumbers show brown sores with the release of liquid - they cover the entire fruit, and it is no longer usable. In just 8 days, this disease can destroy the entire crop in the greenhouse.It is necessary to air the greenhouse more often and not to allow the temperature to drop.Also, if desired, pinch off side shoots and flowers. In the middle part of the sprout, pinch lateral shoots above the first leaf, and at the top of the sprout - above the second leaf. Also, antennae, yellowed leaves, shoots from which the crop has already been harvested are removed.

To eliminate the disease using special drugs. Of the most affordable and common - solution of manganese, sulfaride, mullein, the solution of which is sprayed with plants.For the early cultivation of cucumbers in the greenhouse to be as efficient as possible, it is necessary to create certain conditions. First of all, this refers to the organization of the smooth functioning of all greenhouse systems, soil preparation and the prevention of plant diseases.According to the biological affiliation, cucumbers belong to the liana-like plants of the pumpkin family. In the world, there are and are grown more than 80 varieties for open ground and about 60 for greenhouse cultivation, differing primarily in the method of pollination. These are so-called parthenocarpic varieties that do not require pollination by bees.

  • The reason for this may be a lot of reasons, such as moisture and high humidity, watering with cold water at night or a sharp decrease in soil temperature. These conditions attract cucumber diseases, due to which the stems and the root system of the plant may succumb to rotting.

Planting cucumbers in the greenhouse

At the beginning of flowering, the following method of feeding cucumbers is often used, which, by the way, can generally be combined with the previous option: 0.2 g of zinc sulphate, 0.3 g of manganese and 0.5 g of boric acid.

That is why, at the very first signs, you should immediately stop watering for a week, carry out thorough airing on warm days and remove the film from the garden, but on cool days it is best to keep warm. Plants should be treated with a 1% solution of foundationol or bordeaux mixture. It is possible to spray only from a sprayer, in warm weather in the morning, twice with an interval of a week. And immediately after the treatment of the plant, it is important to dry well, and open the vent on one side.Up to 18 degrees heat.Greenhouse cucumbers must be of a certain type. When choosing a cucumber variety, special attention should be paid to the way in which they are pollinated. If the vegetable is pollinated by bees, then

All questions about cucumbersWhat to do if the leaves of cucumbers turn pale?In case of violation of the thermal regime, which often occurs in our greenhouses, foliar dressing is also possible. To do this, you need to prepare the following solution: for a bucket of water - 2 g of potassium permanganate, boric acid and copper sulphate. Processing is carried out in the evening or in the early morning, sprayed to the maximum the lower part of the sheet, which is able to quickly and well absorb the solution.

  • Careful withdrawal from caring hands - and cucumber diseases in the greenhouse will be bypassed.
  • Such insects as ants, aphids, and mites can also be very harmful to cucumbers. For their extermination use special preparations.
  • It is necessary to make the bee easily get into the greenhouse

Then you should regularly ventilate the room, while avoiding a decrease in air temperature below 20 ° C during the day and 18 ° C at night.

For growing cucumbers in the greenhouse, you can prepare the same soil composition as for the seedlings:

Formation of flowers in cucumbers occurs according to the principle: only 5 to 7 male inflorescences in one outlet of the leaf, or only 2-3 female inflorescences. Under normal conditions, male flowers begin to bloom first, but in greenhouses, at low temperatures, with the first regular feeding, female flowers begin to bloom first.

There are many ovaries, but no cucumbers - what is the problem?We all understand how to grow cucumbers in a greenhouse. Somewhere there is own knowledge, somewhere we use the advice of professionals. Но всегда существует то, что может помешать хорошему урожаю - болезни и вредители огурцов в теплице, с которыми нам приходится бороться.​​Посадка огурцов в теплице, уход за огурцами в теплице, сама агротехника и процессы выращивания достаточно сложны, так что стоит подходить к вопросу со всей ответственностью​

​Очень часто выращивают огурцы в парниках. Парник – это небольшое пленочное укрытие для выращивания растений. Seeds or seedlings of cucumbers are usually planted in a greenhouse in mid-May. It is necessary to care for plants in the same way, if they grew up on an open garden in the ground. When planting cucumbers

Cucumbers, which are grown in the greenhouse, are fed several times during their growth.

In addition to diseases of greenhouse cucumbers, all kinds of insect parasites are dangerous. First of all, it is necessary to protect plants from aphids, ticks, thrips, ants, wireworms, germs of the germ fly and others.Peat soils are also suitable: peat - ½ part of the total volume, humus - ⅓ part, field fertile soil - part.Superearly varieties of cucumbers for greenhouses after only 40-45 days from the appearance of the first shoots,

Why do cucumbers rot in the greenhouse?

But only on your desire will depend on the final result.The problem may be that there is not enough fertilizer. Try to feed the cucumbers with a mullein, during the decline of the same crop for watering 100-200 g of humus and a pinch of urea for watering in a bucket of water.

There are plenty of ways to prevent and fight, and

Before you sow cucumbers inside the greenhouse, you need to carry out a number of preparatory work. The soil in the greenhouse and greenhouse should be qualitatively disinfected. These actions should be applied to the greenhouse itself, the grounds and risers of which in the future may become a source of diseases and infections. To do this, use a solution of bleach - tincture 40 g of lime in 12 liters of pure water for two hours (processing in the fall), and boiling water with manganese - 3 g of manganese per bucket of water (processing in spring).Most often used dung beds, with the addition of lime in themIt is necessary to feed at the beginning of flowering

Disease # 4 - Gray Rot

For the prevention of the appearance of pests or to combat those that have already appeared in specialized stores, there is a whole arsenal of tools, but many gardeners successfully use proven folk remedies with a sufficiently high efficiency.

Bushes seedlings better planted in prepared beds with a height of about 15 cm and a width of 60 cm, the same amount should be left for the distance between rows.

Early - after 45 days,

Disease # 5 - Ordinary Cucumber Mosaic

The reason for this may be a lot of reasons, such as moisture and high humidity, watering with cold water at night or a sharp decrease in soil temperature. These conditions attract cucumber diseases, due to which the stems and the root system of the plant may succumb to rotting.

In case of violation of the thermal regime, which often occurs in our greenhouses, foliar dressing is also possible. To do this, you need to prepare the following solution: for a bucket of water - 2 g of potassium permanganate, boric acid and copper sulphate. The treatment is carried out in the evening or in the early morning, sprayed to the maximum of the lower part of the sheet, which is able to quickly and well absorb the solution.

Disease # 7 - Perinosporosis

Agrotechnics of growing cucumbers in greenhouse conditions practically does not differ from agrotechnics in relation to the open ground. Growing cucumbers in a greenhouse in winter and summer is possible only if the necessary conditions are created

. Fertile soil or peat mixed with sawdust is poured into the wells, and mineral fertilizers are also added to the soil.

With such a mixture: 1 cup of chicken manure and 1 cup of nitrophoska are diluted with 10 liters of water. After 10 days, you should make a special solution that must be poured into the well. The solution consists of water and manure. You can also use such feedings as:

The prerogative of growing cucumbers in greenhouses is given, above all, because of the unique taste of the vegetable, the variety of its uses, and its good preservation. Regular consumption of this product favorably affects the whole body: from elementary replenishment of vitamins to regulation of the general and fatty metabolism, potassium-sodium balance, cardiovascular system, etc.

Why do cucumbers turn yellow in a greenhouse?

. Can damage not only cucumber, but also other cultures. By sucking the juice from the leaves, the whitefly leaves a special discharge on the leaves, on which, in a consequence, soot fungi are formed. You can fight with the whitefly in simple ways: remove weeds in time, arrange glue traps, wash plants.

An increased supply of carbon dioxide is needed, which has a positive effect on the formation and development of female colors. To do this, it is necessary to introduce organic matter into the soil. You can also scatter mullein around cucumbers, but only so that it does not touch the plants.

Soil preparation for planting

First of all, attention should be paid to the soil from which the plant will receive its main food. This should be done in the autumn: before digging, make fresh manure, phosphate and potash fertilizers, lime or chalk. Cucumber is very picky about nutrition: the best soils for it are loam with a high nutrient content and an acidity level of 6.5-7.

Important! Nitrogen fertilizers are applied to the soil only in spring.

Seed selection

You can plant cucumbers with seedlings or seeds immediately in the greenhouse. Seeds need to choose the right, it is better to use hybrids, as their flowers do not require pollination by insects. These are the so-called parthenocarpics: all the flowers of such plants are female, and the fruits are tied by themselves.

Here are some well-proven varieties of hybrids:

Pollinated varieties need insect pollinators. In their absence, pollination must be carried out manually. You can attract bees in this way: sprinkle in the morning the foliage of the plants with the infused sugar syrup with a few drops of anise oil added. Do not forget to open the vents so that insects could get into the greenhouse.

Here are some popular bee-pollinated varieties for greenhouses:

By appointment varieties are divided into salad, pickling and canning.

The terms of fruit ripening are also different:

  1. Early: fruiting occurs 40-45 days after planting.
  2. Mid-season - 45-50 days.
  3. Late: fruiting occurs after 50 days or more.

Landing on a permanent place

Before planting seeds or seedlings, it is advisable to disinfect the soil with a weak solution of hot manganese or 7% solution of copper sulphate in order to avoid the development of diseases in cucumbers. After the beds are ready, you need to stretch two rows of wire at a height of 1.5-2 m with a distance between rows of 20-30 cm - for garter bushes. You can use plastic mesh instead of wire. It should be strengthened slightly obliquely, so it will be convenient to harvest. Moreover, the plants with this method are better illuminated, respectively, and the yield is higher.

Plant the seedlings along the wire rows or sow the seeds into the wells 1.5-2 cm deep at a distance of 50-60 cm from each other. After completing the work, water the seedlings again.

Important! When planting seedlings should not bury the root neck, as this can lead to the death of the plant.

Nutrition strategy

During fruiting, plants constantly require nutrients and carbon dioxide for photosynthesis. The more gas, the better. In greenhouses, compost and organic mulch are the main sources of carbon dioxide. You can increase the gas content by putting any container half full of fresh manure or bird droppings into the greenhouse. When this mixture is fermented, it is used for dressing, diluted with water in the right proportion: manure 1:20, and bird droppings 1:40. This simple method increases the yield.

But organics are not always at hand, so you can use ready-made mineral mixtures for pumpkin crops to feed cucumbers. The cucumber responds very well to foliar nutrition by foliage from a sprayer with the following composition: for 10 l of water, 2 g of boric acid.

90% of cucumber fruit consists of water and this explains the strong dependence of the plant on it. Humidity of the soil should be constant, without jumps from excessive moisture to dryness. Both shortage and excess moisture are very harmful:

  • ovary crumbling
  • fruits twist and become bitter,
  • leaves perish,
  • the harvest is sharply declining
  • root rot and other diseases occur.

Water used for irrigation is necessarily warm, somewhere +20 - + 25 ° C. You can not water the plant at the very stem, as this exposes the roots. If this has already happened, then pour the land. It is very effective to apply mulching. Mulch does not allow the soil to dry quickly, the crust does not form on the soil surface, the temperature regime remains constant, soil aeration is doubled, weed development is suppressed, which reduces the amount of weed. Use any organic material available. Peat, compost, fallen leaves, straw, grass-cutting in the sun will do.

Attention! Soil temperature should be constant - +22 - + 24 ° C. At a temperature of + 13 - + 15 ° C, cucumber roots do not absorb water.

It is no secret that watering takes a lot of time and effort from a gardener. Nowadays, drip irrigation systems for polycarbonate greenhouses are gaining popularity. The most important advantage of such systems is the minimum of participation in the process; a person can only open and close the tap. In addition, water consumption is reduced several times, while the water is supplied guaranteed to the roots.

Pinching and shaping

In the greenhouse, whatever its size, it is necessary to form cucumbers. Removing all unnecessary from the bush, we redirect the power of the plant to the development of the fruit, improve the illumination and air circulation. Forming allows you to get more yield from a smaller area.

For parthenocarpic varieties, light is important, and the shape of the bush is almost irrelevant: the formation of the ovary does not depend on the presence of insect pollinators. Basically, fruits are formed on the side branches of the plant. Parthenocarpics, as a rule, branch very well, it is convenient to carry them with one liana on a trellis. After the appearance of the first ovary on the plant, it must be removed, it will give impetus to the intensive development of the plant. In the future, all lateral branches need to pinch after the formation of 3-4 fruits. When these shoots appear new shoots (3rd order), then pinch over 2-3 sheet.

Surveyed varieties, as a rule, form into several shoots. On the main stem, they form mostly male flowers - barren flowers, and on the side, mostly female. They branch quite late, so you need to pinch the main stem over the sixth leaf and feed the plant so that it quickly opens new shoots and forms the ovary.

Council Cucumber shoots are very fragile, so that the plant is less injured, pinch with sharp scissors, leaving no hemp.
