Hortensia attracts many gardeners, both experienced and beginners. The plant is valued for its decorative appearance, unusual leaf shape and lush flowering. It owes its name to the French princess Hortensia. Later scientists called it hydrangea, which translates as "a vessel with water." This emphasizes the fact that the plant needs a lot of moisture. However, the scientific name did not stick with the florist. Until now, preference is given to the original version.

Varieties

Hydrangea is most often grown in gardens, but it is possible to maintain a flower at home. There are about 80 varieties of this plant. There is also a division by type:

  • paniculata,
  • Anabel,
  • large-leaved,
  • petiolate,
  • tree,
  • pink

In room conditions it is recommended to contain large-leaved hydrangea. This is due to the fact that it is less resistant to frost and does not tolerate temperature drops. Various types of flower are common in the territories of East Asia, South and North America, Sakhalin, the Kuril Islands, and Japan. China is considered the birthplace of large-leaved hydrangea. In a warm subtropical climate, the plant can reach 4 meters in height. In colder climates, it can only grow to a meter. In nature, hydrangea flowers are pink. Today, breeders have brought new varieties with white inflorescences. But the most unusual is the large-leaved hydrangea.

Temperature and location

Often, novice gardeners can hear that the plant is difficult to maintain. This opinion arises from those people who do not know how to care for blue hydrangea. You should always remember that the flower belongs to the heat-loving. In the summer he needs a temperature of 18-20 degrees. If the room is warmer, the plant will start dropping leaves. The flower loves fresh air, so in the summer it is advisable to bring it to the balcony. However, you must avoid drafts and cold air flows. In winter, the optimum temperature is 4-8 degrees.

In the summer, in the period of flowering and active growth, the hydrangea should be located in the penumbra or in the place where the light is diffused. It is best for the flower when the top is lit, and the stem and leaves are in faint shade. Hortensia blue does not tolerate the direction of the sun's rays, however, very dark places also do not suit it. The flowering period begins later, and little plants appear on the plant. In addition, the lack of lighting leads to the fact that the blue hydrangea becomes weak. Do not allow contact of the flower with the glass. This will cause burns on the leaves.

Humidity. Watering

In the period from spring to late autumn, blue hydrangea requires abundant watering. However, it is important not to overdo it. Watering is done as the topsoil dries. Water should be soft. Periodically, the plant must be sprayed. In winter, the frequency of watering is reduced to 1 time in 1.5 months. Hydrangea blue is able to endure a little dryness, but one should not allow complete drying of the earthy coma.

For planting plants, you can take the finished substrate. If the necessary soil in the store was not found, then you can prepare it yourself. To do this, take 3 parts of sod, 3 parts of leafy ground and 1 part of sand. Hortensia loves acidic soil. The pH should be 4-5.5. The more acidic the soil becomes, the darker the flower becomes.

In the period of flowering and active growth, blue hydrangea requires additional nutrition. For this purpose, a complex mineral fertilizer is used for plants that prefer acidic soils. Feed once a week. Per liter of water is enough 2 g of fertilizer. It is worth noting that a large amount of it badly tolerates any plant, including blue hydrangea.

Planting and care. Reproduction. Transfer

There are several types of breeding hydrangeas. The simplest and most effective for indoor flower is cutting. To do this, take the lower young shoots with a length of 7-8 cm. They should be 3-4 pairs of leaves. Cut cuttings should be smooth, not at an angle, at a distance of 3-4 cm from the first node. Lower leaves are removed. Planting is done in deep containers filled with a mixture of peat and sand to a depth of 1.5-2 cm. You can cover the cuttings with a glass bell, but it is better not to do this, as they can rot.

3-6 weeks is enough to make the blue hydrangea take root. Care for a young plant needs careful. In the first seven days it is sprayed up to 4 times a day, then reduced to 1-2 times. After rooting, the plants are transplanted into pots with prepared soil. To bush was more magnificent, it should be pinched in May. The hydrangea will bloom next year.

If the hydrangea bush has grown big, then it is better to plant it. For this, the plant is divided in half so that both top and root are on both parts. Hydrangea bushes are planted in a flower pot and fed with fertilizers. Additionally, the root slice is treated with phytohormones.

It is carried out in the spring before the beginning of the vegetative period. The essence of the procedure is to remove weak and strongly stretched shoots and old inflorescences. As a result, the plant will bloom better. In addition, there will be new strong shoots. But do not be zealous. Heavily cut hydrangea blooms badly. On the shoots need to leave from 2 to 6 pairs of healthy buds. After pruning, hydrangea does not need to be fed. If the hydrangea grows too thick, then part of the shoots can be removed by cutting at the root.

Rest period

Beginning growers may be concerned, noticing that the hydrangea leaves fall. If this happened in winter, there is no reason for excitement. The flower began a period of rest, which lasts about 3 months. Of course, it’s hard to admit a blooming beauty in bare branches, but if you wait for the summer, you can be sure that it’s the same beautiful blue hydrangea. How to care for the wintering flower? This process is very simple. Watering is significantly reduced, but the earthen clod cannot be allowed to dry. Fertilizing is not needed. Until March, hydrangea is cleaned in a cool dark place. Young plants, whose shoots are not woody, do not shed their leaves and hibernate without entering a state of rest.

Diseases and pests. Ways to fight

Among the pests stand out:

  1. Aphid. To get rid of the pest, you need to treat the plant with soapy water. In the case of a strong defeat, one will have to use phosphoorganic insecticidal and acaricidal preparations of a broad spectrum of action.
  2. Spider mite Spraying will help in the fight against it. Water should be used warm. If you can not achieve a positive effect, you can use the drugs used to eliminate aphids.

Hydrangea is subject to the following diseases:

  1. Stem nematode. Leaves, stem and inflorescences are subject to the disease, as a result of which the plant loses its attractiveness. It is impossible to save the affected flower. It will have to be destroyed to avoid spreading the disease to other plants.
  2. Downy mildew. Manifested in the leaves and stems in the form of oily spots. Over time, they turn yellow and increase. On the back of the affected leaf occurs yellowish bloom. Due to the high humidity and temperature of 18–20 degrees, blue hydrangea is affected by powdery mildew. Care and treatment of plants consist in the treatment of the affected areas of the plant with copper-soapy water. In 10 liters of water to dissolve the blue vitriol (15 g) and green soap (150 g).
  3. Chlorosis. Hortensia, affected by this disease, has light leaves with dark veins. Chlorosis causes a large amount of lime or humus in the soil. To return the plant to its former appearance, it is necessary to dilute potassium nitrate (40 g) in 10 liters of water and water the flower 2-3 times. After 3 days, a solution of ferrous sulfate is used in the same proportions.
  4. Hortensia is very sensitive to light and watering. If the flower lacks moisture, its leaves will begin to turn yellow and curl. Excessive watering leads to decay of the roots. This most often happens during a period of rest when the temperature is significantly reduced. Excessive refreshment leads to the formation of light spots on the leaves. With a lack of plant grows slowly and does not bloom.
  5. Quite often novice growers are faced with the fact that the hydrangea leaves wither. The causes of this problem are several. First you need to find out if the flower gets enough moisture. The plant may be in direct sunlight. Leaves can wither from a lack of nutrition, namely from a lack of nitrogen fertilizers. If the location is chosen correctly, watering is sufficient and regular feeding is present, then hydrangea is sick with chlorosis.

The flower can be grown not only on the windowsill, but also on the street, of course, if the climate allows. Hydrangea will not leave anyone indifferent, thanks to its unusual appearance. She is not the most difficult plant in the care. If you wish, even a novice will cope with it, and beautiful flowers will be a reward for your care.

Blue hydrangea can also be used in design. Its decorative look will easily decorate any room. The flower is perfect for decoration theme parties or weddings. If you need to create an atmosphere of tenderness and romance, hydrangea perfectly cope with this task.

Lighting and location

The plot of a garden with light penumbra will be the best place to grow a wonderful flower. It is great if the sun beams on the flower in the morning and evening, but not in the daytime. The requirements for the level of illumination are quite modest - for the normal development and lush flowering of Nikko Blue, a six-hour day is sufficient.

Air humidity

For hydrangea of ​​this type is better high humidity, week drought. If the summer is very hot, take care of additional watering and spraying the plant to preserve its decorative qualities.

Large-leaved hydrangea - the plant is quite tender and does not like coolness. Therefore, it is necessary to protect it from winds and drafts. Choose a place on the leeward side, or make sure that from the north hydrangea is protected by buildings, a fence, and other safe shields.

The soil for this plant should be fertile, rich in humus. Acidity is desirable or weak or low. In too acidic soil, even if hydrangea can please with bright blue flowers, it cannot develop normally for a long time.

The optimum level of acidity is 5.2-5.5 Rn: already at this relatively low level, the hydrangea petals become saturated in color. Hydrangea cannot grow in alkaline soil.

It is important that the bed has good permeable properties, is loose and drained. Stagnation of moisture for hydrangea is highly undesirable, as it negatively affects the state of its roots.

Consider the main points regarding the rooting of Nikko Blue hydrangea.

Training

Experienced gardeners are advised to plant this flower in the spring, but if in the fall, it is only until the beginning of October.

The pit is prepared in such a way that its parameters coincide with the volume of the roots of the seedling. But since the bush will grow quickly enough, it is recommended to make the pit parameters not less than half a meter by half a meter. The depth is the same.

The pit is half filled with the following mixture:

  • peat - 2 parts,
  • garden loose earth - 2 parts,
  • humus - 1 part,
  • rotted needles - 1 part.

If the soil is dense and clayey, take care of drainage by placing small pebbles - expanded clay or pebbles on the bottom of the pit. This measure will prevent stagnant moisture in the soil and protect the roots of the plant from rotting.

The roots of the seedling just before planting should be soaked in water.

Landing process

  1. The seedling is placed vertically in the center of the pit.
  2. Roots sprinkled with soil.
  3. The root neck is slightly buried, but not completely - there are sprouting buds on it.
  4. The seedling is sprinkled with soil with simultaneous compaction.
  5. When planting is completed, it is recommended to water the plant in order to activate its vitality and speed up adaptation, survival.
  6. From above, the soil is mulched with dry peat, sawdust and pine needles - this organic layer will serve both to protect the soil from drying out, and additional nutrition.

Large-leaved hydrangea - moisture-loving plant. Therefore, they water it in a dry summer 2 or 3 times a week, pouring up to 40 liters of water under an adult bush. The soil under the bush must be mulched with coniferous litter, pine bark or sour peat.

In June, the active formation of buds begins. Therefore, the plant must be fed, during this period it is particularly in need of phosphorus and potassium. Nitroammofoska or superphosphate will be suitable for feeding. It is enough to take 1 tbsp. l fertilizers for 10 liters of water; 1/2 a cap of a special fertilizer for hydrangeas, which contains trace elements necessary for the plant, is also added to the solution.

From the potassium permanganate prepare a slightly pink solution and shed for the season hydrangea bush 3 - 4 times. This will help to strengthen the shoots.

It is also good to use green fertilizer in June - an infusion of weeds. The second stage of feeding is carried out when the flower brush is visible, and the buds begin to form.

Fertilize hydrangeas only on wet ground, after rain or watering. On a large bush enough 10 liters of water with diluted fertilizer. It is good to conduct foliar feeding on the leaf, if the plant is weakened.

There are several ways of breeding garden hydrangea:

  • cuttings
  • seeds
  • layering
  • dividing the bush
  • root suckers.

For grafting, the best time is the first half of summer. Cut off the young side shoots without signs of disease, divide them into several parts so that each leaves 2 to 3 pairs of leaves. Rooted in water or a mixture of peat and sand, covered with a jar. For better root formation, the lower section is treated with “Kornevin”.

The seeds collected independently from a bush are not suitable for reproduction.

Plants grown from them will not inherit parental traits. Seeds need to buy in the store.

Hydrangea is a moisture-loving plant, so it needs regular and fairly abundant watering. No wonder the word "hydrangea" in translation from ancient Greek means "vessel for water." Watering the plant is necessary from spring to late autumn - autumn watering helps hydrangea roots not to freeze in winter.

The soil on the flowerbed should always be hydrated, but slightly, you should not bring the matter to the pouring. Hydrangea roots are very tender and sensitive, they sharply react to excess moisture, they can easily rot.

In order for the shrub to grow normally, to develop safely and bloom magnificently, care must necessarily provide adequate additional nutrition.

Complementary feeding in the spring, when the leaves start to bloom. For the first time in a season, a nitrogenous feed is added to the ground, which helps to form lush and bright greenery faster.

Before the beginning of flowering, hydrangea Nikko Blue is fed a second time, using potassium-phosphate compounds. This dressing contributes to the lush and prolonged flowering plants.

It is better to feed the shrubs with compositions specifically designed for hydrangeas - the components in them are selected in the most optimal way. You can use and organic: humus and diluted slurry. It is impossible to apply ash to alkaline soil for fertilizing hydrangea.

Loosening, mulching

After watering, it is recommended to mulch the root circle of the shrub to keep the moisture at the roots longer. At the same time, the earth should be loosened in order to make it more permeable, light, to provide air exchange to the roots.

The trimming procedure is obligatory for all types of hydrangeas, and Nikko Blue is no exception. The procedure helps to form a compact and neat crown shrub, and also contributes to the lush, long flowering.

In this type of hydrangea, flowers are able to appear only on annual shoots, therefore it is imperative to get rid of old, outdated branches. However, you should carefully consider the procedure - the flowers bloom at the end of the shoots, so it is important not to overdo it.

In the first year after planting, the spring shoots are shortened by one or two buds, and weak shoots are completely removed to the base. If found healthy and young, but growing inside the bush escape, it also must be cut to the ground. Similar branches will negatively affect the shape of the shrub.

In the second year after planting, pruning is done after the flowering of hydrangeas. Strongly grown branches shorten, remove old, diseased and protruding shoots.

In the third year, as well as all the other years, Nikko Blue's hydrangea is cut off after flowering, cutting off all the branches down to the lower growths. As you already know, giving flowers last year's shoots are not capable. If the branch is weak, it is cut clean. If necessary, thin the shrub, mostly old branches are removed, and also to the base.

This procedure is best done either in the spring before the start of sap flow, or in the fall after flowering. But during active flowering transplant is extremely undesirable and leads to the loss of decorative elements by hydrangea.

Experienced gardeners choose an autumn transplant, as it produces the best results. The optimal time is mid-September: the flowering has already ended, but it is still far from the real cold, and the plant will have time to take root.

It is important to transplant the hydrangea together with the earthy clod, and you need to get some of the soil in such a way that the roots are not damaged.

Hortense Nikko Blue is a tender plant, she will not survive our cold without shelter. And since its winter hardiness is low, in the northern regions this hydrangea is not even trying to grow in open ground, but is planted in containers that are cleaned into the room for the winter.

If the climate in your area is not as severe as in Siberia, you can cultivate this beautiful shrub and in an open garden. However, it is necessary to shelter a plant already in the second half of October - it happens that frosts come unexpectedly.

Shelter is produced by a greenhouse film that protects the shoots from both cold weather and moisture. And in order not to freeze the roots, at the base of the plant, soil is spud, and then the basal circle is covered with peat (30 cm layer). If the shoots of the hydrangea are long, they should be bent to the ground, secured and insulated with spruce leaves, fallen leaves.

In the spring, it is necessary to remove the shelter as soon as the snow melts, since excessive moisture under the “blanket” can negatively affect the condition of both the roots and the shoots of the hydrangea.

Planting in open ground

For planting fit saplings of three-year shrubs. It is necessary to acquire them in special shops where plants for growing are sold, for sure there you will be able to buy high-quality goods.

Plant the plant as follows:

  1. Dig a hole 50 cm wide and about 40 cm deep, and one day before planting, pour 5–6 buckets of water into it so that the earth is soaked with moisture.
  2. The next day, you need to add nutrient soil and some mineral fertilizers to the root to stimulate root growth.
  3. Then the seedling should be placed in the hole and gently sprinkled with earth, then slightly condense it around the plant.
  4. Now the young hydrangea needs to be poured abundantly with water and to put peat or coniferous needles on the soil surface around the plant.

Care for ornamental shrubs

First of all, blue hydrangea needs regular watering, as it very moisture-loving. Inadequate hydration greatly affects the flowering and well-being of the plant.

Watering should be 2 times a week, pouring 4–5 buckets of water under each bush. The main thing is never to allow the soil to dry out around the plant. In hot weather the bush is recommended. periodically spray. In winter, watering can be reduced to 1 time per month.

Top dressing is also a necessary step in the care of hydrangea. The first time you need to make fertilizer in the spring, it should consist of a mixture of superphosphate, potassium sulphide and urea. The second feeding should be carried out in July, during the formation of buds, here it is necessary to use superphosphate and potassium sulphide. And the last nutrient intake should be in September with the use of organic fertilizers.

Periodically the bush must be exposed pruning. If this is not done, the bush will grow to a shapeless mass and will not look aesthetically pleasing. Pruning is recommended in several stages, given that all varieties of blue hydrangea bloom on last year's shoots.

To put the plant in order, you must do the following:

  • At the end of March - beginning of April, a small amount of old shoots must be removed with the help of garden scissors, simultaneously removing dry and damaged branches.
  • Annual shoots should also be slightly pruned, leaving about 6 buds.
  • If the shrub is too thick, part of the shoots can be cut completely.
  • With the onset of autumn is recommended to cut all the flowers from the bushes.
  • Feed after this procedure is not required.

In late November, the bush begins to shed its foliage, so the plant prepares for the onset of winter. The rest period lasts 3 months, and with the arrival of warm days, the blue hydrangea revives again and begins to recover quickly.

To care for the plant in winter is quite simple.. To do this, first of all, reduce watering, but do not allow the soil to dry out. Feeding at this time is also not needed.

If the hydrangea is planted in a separate pot, you need to put it in a cool and dark place, and plants that grow in open ground need to be covered before the onset of frost.

Diseases, pests, other problems

Along with its exceptional external beauty, Nikko Blue's hydrangea is also quite vulnerable to disease and pest damage. In addition, there may be various negative symptoms in violation of the rules of care. Especially often the plant suffers when cultivated in a cool climate. Next, we consider the most common problems when growing hydrangea Niko.

Gray rot

Also fungal pathology, which often suffers hydrangea. Gray rot - a dangerous disease and often leads to the complete death of the plant. The rot appears as spots on the lower part of the stem, which then spreads to the whole stem and leaves. In place of the spots, through holes are formed over time, which greatly spoils the decorativeness of the flower.

They fight against gray mold by digging the plant out of the ground and destroying it. This measure does not allow pathology to spread to other hydrangeas. The soil must be treated with disinfectants, since the fungus is transmitted through the soil.

Among harmful insects, the following are dangerous:

  • spider mite,
  • grape snail,
  • slugs
  • scythe,
  • leafworm,
  • aphid and others

Fight insects by spraying the plants with suitable insecticides. This treatment is best done proactively to prevent infection of the shrub.

There are more positive reviews of this plant on the Internet - thanks to its impressive decorative properties, Nikko Blue's hydrangea managed to win many hearts. Almost everyone notes the duration and pomp of its flowering, many write about the spectacular view of a hydrangea bush.

Negative reviews indicate the instability of the plant to a cool climate, susceptibility to diseases and pests, some effeminacy and moodiness. But if the gardener was able to cope with Nikko Blue's obstinate character, the plant will delight him for many years.

Hortense Nikko Blue - a wonderful copy of garden culture, which, however, can be grown indoors. And although caring for a plant is quite troublesome, many strive to plant this beauty - its gorgeous blue, lush flowers do not leave anyone indifferent.

Trimming Blue Hydrangea

It is important to properly form a shrub. Gardeners do not like to prune the branches, but in the case of hydrangea paniculata without a strong pruning you can not wait for abundant flowering.

  1. In the fall, cut off all the inflorescences.
  2. In the spring, all growing inside the bush, weak and frozen branches are cut out on the ring.
  3. In the spring, one-year growth is shortened, leaving no more than five pairs of buds on each.

Such pruning contributes to the fact that every year the bush will bloom more magnificently. What does “abundant flowering” mean in the case of hydrangea paniculata? A five-year copy with good care will please the owner with several dozen panicles, and a twelve-year-old with a few hundred! The plant lives in the garden for 50 years or more. A copy older than 20 years can be rejuvenated by cutting the bush on the stump. But even this pruning does not prevent the plant to bloom in the same year.

How to make hydrangea blue

There are several varieties of large-leaved hydrangea, which are able to change the shade of their colors depending on the composition of the soil. If the soil where the bush grows is quite acidic, then the inflorescences change their color themselves, for example, the pink will turn purple or purple over time, and the white will become blue.

But you can try artificially change color buds and here's what to do for this:

  1. Before planting hydrangeas add peat or sulfur to the ground to create an acidic environment.
  2. You can regularly water the bush with a solution of ammonium sulfate - 15 grams per 1 liter of water to preserve the acidity of the soil. Before such irrigation, it is necessary to take into account that the earth around the plant is moistened with ordinary water, otherwise the solution may burn the hydrangea roots.
  3. To maintain the acidity of the soil, it is recommended to use natural products, such as, for example, solutions from orange and lemon peels, drunk coffee, needles of coniferous trees.
  4. Special fertilizers suitable for blue varieties of hydrangeas also give a very good result on the change in the color of the buds.
  5. If you bury some iron items near the plant, this can also affect the change in color of the inflorescences.

It should be remembered that it is impossible to use all these methods for a long time, as the soil composition may irreversibly change for the worse and it will be impossible to grow other plants in this place. Therefore, experienced gardeners recommend planting a blue hydrangea in special pots designed for such plants, which can be immediately filled with a certain soil and without problems keep it in the desired composition.

How to grow a blue hydrangea

Hydrangea blue - flowering garden shrub. It looks great in landscape compositions, suitable for decorating hedges, decorating arbors, paths. At present, many varieties have been bred that easily tolerate winter and delight with their flowering for many years.

A separate type of "hydrangea blue" does not exist. This name was given to the plant for the shade of its flowers. Blue and blue inflorescences covered varieties of hydrangea, mostly. There are two- and three-colored species that change their shade throughout the season.

In addition, large-leaved hydrangea is easy to "repaint." It is only necessary to create appropriate conditions. What varieties have blue inflorescences? How to choose planting material? How to grow hydrangea? You will find answers to the questions in the article.

Varieties with blue buds

As a rule, these are large-leaved hydrangeas. They differ in rounded inflorescences, long and abundant flowering.

Initially, large-leaved hydrangeas were seen by flower growers in pot varieties. Such cultures were not suitable for cultivation in the open field. They just froze. And only much later frost-resistant varieties were bred. Which ones have blue flowers?

    Hortensia "Mini Penny".

Remontny grade. Blossoms on the shoots of the current year. It has lush green foliage and pale blue flowers, collected in spherical inflorescences.

Small compact bush. Treats multi-colored grades. Some species are covered with purple or purple flowers. Others are spectacular bright blue with white.

Two color variety. At the beginning of flowering pink flowers appear on the background of rich greenery. Then their middle area turns blue, and the edges turn white.

Hybrid variety with large lilac-blue flowers, the middle of which is white.

Rose-like flowers are pink first. Then the hue changes to blue.

A small bush up to sixty to eighty centimeters with tulip-like blue flowers. Blossoms on the shoots of the second year.

Compact bush with blue terry flowers. Blooms also on the branches of the second year.

These are the most popular varieties. Many of them change color during one flowering period. Pink hydrangea can be bought, planting and care are provided in accordance with the requirements. And then the flowers turn blue. This is a feature of the variety. We just did not pay attention to her.

The color of the hydrangea changes easily. During the budding period, the bush should be watered with aluminum alum (two liters of water - a teaspoon with a slide). Then the white color will turn blue, pink - lilac, purple or blue-blue.

How to plant

For planting are ideal seedlings of three-, four-year shrubs. It is better to buy them in specialized real or online stores. The root system of seedlings must be protected and hidden in any material. In the store for these purposes used containers. Growing consists of:

Hydrangeas love penumbra. Open solar spaces do not like moisture-loving shrubs. In the shade, hydrangea blooms poorly, blooms later. For this plant you need a golden mean.

When planning group plantings, it is necessary to take into account that the growth and development of the shrub requires space. The optimum free diameter around each hydrangea is two meters.

Beautiful flowering shrubs love sour, moisture-consuming and loose soils. To provide similar conditions in the following ways:

  • bring soil from the forest (you need to dig the ground under the pines along with needles),
  • mix in equal quantities high-moor peat, leaf and sod land, sawdust compost, sand.

Hydrangeas do not like it when there is lime in the soil!

The night before dig a hole (width, length and height - half a meter). Pour in five buckets of water. The next day, add the prepared substrate, put a seedling, gently straighten the roots and cover them with earth. Good water and cover with pine needles or peat.

Decorative effect, color saturation, elasticity of leaves and shoots depend on proper watering, trimming, fertilizing.

Hortense loves water. With a lack of moisture, it withers, bad blooms. If under such a plant to give a few buckets of water, it immediately comes to life.

The optimal frequency of irrigation - once or twice a week. Under each bush you need to give three or four buckets. If, after watering, mulch the soil around the hydrangeas, then water sufficiently every ten days. Mulch will keep moisture longer.

Conclusion: in no case should not allow the drying of the soil around the hydrangeas.

The large-leaved blue hydrangea loves top dressing and responds very well to them. Fertilizers need to be depending on the period of plant development:

  • в конце весны – первая подкормка из суперфосфата, сернистого калия и мочевины (2:2:1,5),
  • в середине лета (во время образования соцветий) – вторая подкормка из суперфосфата и сернистого калия (2:1),
  • at the end of summer - the beginning of autumn (during the period of active flowering) - the third dressing, organic (compost or rotted manure).

To protect the hydrangea from diseases, it is recommended to periodically add any fungicide to the irrigation water (especially in the first year after planting).

Conclusion: hydrangeas need mineral fertilizers, in the period of active flowering - organic. In no case should not bring ash!

This is a mandatory step in the care of shrubs. Regardless of the variety. Treelike, Grandiflora, paniculate, Japanese, hydrangea Phantom ... Planting and care will not be complete without pruning.

Almost all varieties of large-leaved blue hydrangea bloom on the shoots of last year. This should be considered when pruning. It is important to keep the flower buds at the ends of the branches.

In the fall of the inflorescence do not touch. They will protect the flower buds from winter frosts. They can be removed in spring:

  • in April, completely cut off a quarter of old shoots that are more than three years old,
  • the rest - only last year's inflorescences,
  • remove weak, diseased and overly exposed branches.

Conclusion: you can not shred large-leaved hydrangea, because the inflorescences appear only on last year’s branches.

Wintering blue hydrangea.

From the end of the summer actively water the plant. It should meet the winter quite strong. To prevent the shoots from mating under the shelter, treat the bush with Bordeaux mixture.

In late October, when there are slight frosts at night, hydrangea can be covered with perforated polyethylene or agrospan. At the beginning of November, tilt shoots to the ground, cover with spruce branches or dry leaves. And put the box on top.

Conclusion: blue hydrangea varieties are prepared for winter, like roses (reliably protect against frost).
