Dendrobium is a bizarre nymph living on a tree. These flowers make up their thoughts about something fabulous, magical.

“Flowers are the remnants of heaven on earth” - John of Kronstadt.

Among the simple exotic flowers grown on the windowsill, it is already common to see Dendrobiums. These are representatives of the genus of herbaceous perennials of the Orchid family, from the Greek "dendrobium" is translated as "living on a tree." There are species living on the stones.

In nature, the Dendrobium flower grows in Japan, China, Australia, Oceania, New Zealand and New Guinea, in the Philippines, has more than 1,200 species, differing not only in color, shape of flowers, leaves, but also in flowering time, the habit of arranging flowers on the stalk ...

Dendrobium is an orchid of small stature, from 40 to 90 cm, the stem consists of cylindrical pseudobulbs. The leaves of the lanceolate form, from 5 to 10 cm, are placed alternately on the stem. From the sinuses rose stalks, which contain from one to four fragrant flowers, with a diameter of 6-8 cm. All sorts of colors: white, yellow, orange, lilac, two and tricolor.

Growing conditions

Dendrobium rather unpretentious plant, care will not be difficult. Since the Dendrobium orchids are representatives of the epiphytic family (“growing on a tree”), dry air, a lack of lighting, and an excessive amount of moisture have a very negative effect on their growing season.

A variety of species does not allow to describe all the rules of the content in the home environment of Dendrobium. Every kind of personal whims, but there are general requests that an amateur grower needs to know about. The cultivation of each species must be carried out, adhering to the rules of agricultural technology for this particular species, otherwise the flower will die. General rules:

  • Dendrobiums adore bright diffused light without direct sunlight,
  • flowers, like any orchid, do not tolerate drafts,
  • in nature, the dendrobium does not enter a period of rest, but under room conditions it is necessary for planting flower buds.

People from tropical forests need generous diffused lighting, but without direct sunlight. Autumn-winter period Dendrobium will survive well on the southern window-sills. When there is a lack of lighting, the shoots are crooked, the number of laid flower buds decreases, so you need to use additional illumination with daylight phytolamps:

  • varieties of orchids, with white and pale pink flowers, are much better able to withstand the lack of lighting. When lighting up will feel wonderful on the windows of the north-east side,
  • Dendrobium with bright red, pink, yellow flowers is better to keep on the windows facing south-east and south-west. In winter, transferred to the south side, not forgetting the creation of additional lighting

In spring and summer, the best placement option for dendrobium is western or eastern windows. At noon, if the orchid is on the south side, it needs to be shaved.

Air temperature and humidity

On summer days, the optimum temperature is 20 ° C, in winter - up to 17 ° C. It is allowed to lower the night temperature by 2-3 degrees. Under these conditions, it should limit watering or replace with spraying the substrate every two to three days.

If the ambient temperature rises, the water rapidly evaporates through the stomata on the leaves. Only a part of the moisture they need reaches the roots. For this reason, it is necessary to regulate the humidity of the air. Put the pots on a tray with water and pebbles or wet moss. Spraying will also help. Dendrobium needs high air humidity within 65-70%. Hybrid species grow wonderfully, bloom even at 40-50% humidity.

It is important to spray Dendrobiums in the early morning or in the evening so that the drops of moisture do not cause burns on the leaves.

How to make dendrobium blossom at home


For abundant flowering in the warm period, it is necessary to create conditions for orchid dormancy in winter: feeding and watering should be stopped, the difference between day and night temperatures should be 7-10 o C.

In summertime, temperature fluctuations occur naturally. Winter will have to try: night air temperature should be at the level of + 16-18 o C, but without drafts Increased temperature contributes to the rebirth of flower buds in the "kids". When the roots of fresh shoots appear on the mother plant, it is necessary to begin watering. New sprouts "catch up" with the old bulbs, then watering is stopped until the buds appear and resume when they bloom.

The summer walk on the balcony, loggia, garden, and terrace can be an excellent stimulus for flowering. Fresh air, protected from the wind and direct rays of the place - and in two weeks Dendrobium will inevitably throw out flower stalks.

This orchid blooms from two to four weeks with a wide variety of flowers, depending on the variety: lilac with a yellow center, white with pink tips, crimson, just white and lilac.

How to feed the dendrobium

Feed up from April to September, 2-4 times a month. Fertilizer can be added to the water used for irrigation, or applied half an hour after irrigation by spraying or immersing the container in a nutrient solution. The concentration of the solution is half as indicated on the package.

During flowering there is no need to feed. Additional nutrition is necessary for the plant, if during this period there is a growth of new or thickening of old pseudobulbs.

Important: you can feed only healthy orchids.

Watering dendrobium

Many do not know how to water a dendrobium orchid. You should choose the "right" moment. The signal to start irrigation is drying the top layer of the substrate:

  • in the summer it’s enough to water 2-3 times a week
  • winter watering is minimal.

Watering can be superficial method and immersion. Orchids growing in pots, watered from above, in baskets or blocks - put in water for 3-5 minutes. Substratum between watering need to dry out. It is recommended to water with soft, even boiled water, the temperature of which is several degrees above room temperature. From April to September, watering can be combined with fertilizers rich in nitrogen, potassium and phosphorus. The frequency of dressings - every two irrigations.

Important: Do not allow water to enter the flower stalks, flowers, young bulbs, leaf axils. Otherwise, the probability of rotting tissue is great! If the liquid does get in, it is necessary to gently blot it with a napkin.

Dendrobium in winter: how to properly care for an orchid in a dormant period

Before November-winter bloom, a period of rest begins in November, which lasts two months:

  • The orchid is transferred to a bright, dry, cool place.
  • The desired temperature is around 15-16 ° C during the day and 8-10 ° C at night.
  • If it is not possible to arrange a daily differential, a constant temperature within 10-12 ° C will do.
  • At higher temperatures or humidity, Dendrobium may not bloom.

How to separate and transplant kids Dendrobium:

  • grown to at least five centimeters baby cut off,
  • moisten the roots
  • placed in a half filled pot,
  • fill up the substrate and compact,
  • the growth point is left on the surface.

Sapling certainly fix with the support. Greenhouse conditions are required. Sprinkle the top layer of the substrate between waterings.

How to split a dendrobium bush:

  • pseudobulbs are separated from the parent plant,
  • cut into cuttings with 2-3 knots, about ten centimeters long,
  • put on a raw sphagnum, placed in a zip-package or greenhouse.

The temperature is maintained at + 20-25 o C, airing every day, moisturize. After 14-20 days, the cuttings will take root, then it can be transplanted into pots with a substrate.

Reproduction of dendrobium cuttings at home

Dendrobium breeding cuttings photo

Dendrobium nobile and other species reproduce perfectly by cuttings: you can cut off the apical part of the shoot or completely divide the entire shoot into parts 10-12 cm long.

  • The resulting cuttings are kept in the root solution for a day, and then rooted simply in water in a sterile container, pouring water only on the bottom of the container.
  • After a few months, the plants will have a developed root system, and they can be planted as separate bushes.

Dendrobium grafting is a simple way to propagate an orchid that does not require much attention. The only drawback - you need to be patient, because the rooting process can last up to six months.

Dendrobium transplant at home


Dendrobium transplanted every three years, provided that:

  • the substrate has decomposed, compacted,
  • the plant has filled its roots with all its capacity
  • the substrate has become acidic or saline from frequent watering,
  • part of the roots rotted after waterlogging.
  • It is also recommended that the newly acquired orchid be transplanted, replacing the transport substrate with a more suitable dendrobium.

What pot is needed for transplanting dendrobium?

The pots are usually opaque. Choosing a new container, it should be borne in mind that the orchid can develop only in close containers 3-4 cm more than the previous one. Replanting Dendrobium, you should follow no tricky rules:

  • the plant is placed for 10-15 minutes in a solution of succinic acid (one tablet per liter of warm water),
  • saturated with moisture the roots will get a greenish-milky color,
  • take out, leave to dry for half an hour on a towel,
  • placed on a substrate in a pot
  • old pseudobulbs should be closer to the edge,
  • root neck is left on the surface,
  • roots straighten, gaps filled with bark.

Watered after 3-14 days (depending on the size of the roots), when the wounds heal on mechanically damaged roots.

Important: Replace gently, as the roots of Dendrobium are very fragile.

You can also multiply by cutting off the withered plant stems at ground level and laying horizontally on wet sand. Raw sand support for several months. Closer to autumn, when babies with roots are formed on the stems, transplant them into separate pots.

Dendrobium Substrate

The main ingredient of the substrate for dendrobium is pine bark, the size of the pieces is average, which allows it to dry for a couple of days. Adding moss or peat leads to over-wetting of the roots and decay. The best supplement is a generous handful of charcoal per liter of bark. As a drainage the crushed polyfoam, a pebble, a broken brick will go. Expanded clay is not the best option, as it is able to accumulate salts that negatively affect the root system of an orchid.

Important: the prepared substrate must be disinfected. Spill boiling water, let stand for 10-15 minutes, wait until dry

Root rot

Root rot on the dendrobium photo

The cause of the death of the plant lies in the wrong care. One of the consequences is damage to the root system:

  • excessive moistening of the substrate
  • fertilizer overfeeding,
  • packed substrate
  • insufficient watering
  • overheating of the plant

Determining the degree of damage to the root system is simple. It is necessary to slightly move the orchid. There are no problems with the roots, if the plant sits tightly.

The problem with the roots is obvious if: they are brown, hollow, slimy. In this case, you need to pull the flower out of the tank, remove the rotten and damaged roots. Do not worry if you have to cut off most of the roots: the presence of at least one whole root gives a good chance to revive the Dendrobium. After trimming the roots, spray them with a phytosporin solution, process the ground part for prophylaxis. Let the moisture dry out and transplant the dendrobium into clean soil.

Dendrobium trunk rots

Stem rot on the dendrobium photo

Stem rot usually occurs from the bottom up from the root to the stem to the leaves. This happens when root rot is not eliminated on time.

A secondary fungal or bacterial infection can pick up the baton and aggravate the situation. This is possible if the plant does not help in time: at the first signs of illness, the orchid needs to be treated with phytosporin and transplanted into clean soil.

Dendrobium withers

The consequence of improper care may be wilting of the leaves. They become lethargic, turn yellow and die. The reasons:

  • defeat spider mites,
  • tissue atrophy with a lack of moisture,
  • leaf rot from waterlogging,
  • root damage.

If the leaves are softened and look like a “rag”, immediately cut them off and process the cuts with a fungicide, and also stop watering until the substrate dries to 2/3 of the container's height.

Dendrobium cracks:

Dendrobium cracks photo

  • there was mechanical damage to the plant, for example, dropped, folded the sheet, etc.,
  • excess nitrogen. In order to save the flower, it is necessary to free the roots from the former substrate, transplant. The first few months do not fertilize, then feed potash and phosphate fertilizers. Orchid will be restored about a year.
  • sharp supercooling after watering. You can not put Dendrobium in the winter after a shower on the window sill close to the glass.
  • watering too rare, so the leaves lose their elasticity. After watering, the plant is intensively taken to consume the liquid, dehydrated tissues do not have time to distribute moisture, deform and burst.

Dendrobium leaves turn yellow if:

  • there is a natural aging process
  • affected by diseases and pests (see below),
  • there was a chemical burn with fertilizers or growth stimulants,
  • the plant overheats,
  • stressful situations: relocation, lack of lighting, humidity, adverse air temperature, improper watering.

Sometimes the dendrobium orchid gives unpleasant surprises: why the leaves turn yellow and what to do, you need to decide on the symptoms and speed of exacerbation of the problem. Often the cause of yellowing leaves are pests and diseases, which are more detailed in the next section of the article.

Dendrobium drops buds and flowers

The following factors may cause this condition:

  • a dramatic change in habitat
  • lack of lighting
  • overheating in the sun or from heating,
  • incorrect watering
  • hypothermia

Interesting fact: Dendrobiums are contraindicated near fruit, especially apples, bananas, apricots. They produce ethylene, which contributes to the accelerated aging of flowers and buds.

Dendrobium orchid diseases

Dendrobium orchids turn yellow leaves What to do In the photo bacterial rot

Caring care is not everything. It is difficult to observe the flower so that the pests and diseases do not hit. Diseases cause fungi, bacteria and viruses.

Dendrobium virus diseases

They manifest themselves as unusual spreading spots, the disease develops slowly, gradually capturing new leaves, which eventually die. You can remove old infected leaves, then the young will get a healthy look. But..

Virus on dendrobium photo

Remember: viral diseases cannot be cured, no matter how much you struggle for the plant, it will be sick and even if you remove all the diseased leaves, provide good care for the orchid, the virus will be in a latent state and will manifest itself at the slightest stress: temperature changes, improper watering or lack of essential trace elements. It is better to discard such an orchid in order not to infect the others, and to carry out a wet cleaning in the room with the use of a disinfectant.

Dendrobium Fungal Infections

To cure the dendrobium from most fungal infections, it is necessary to carry out repeated treatment of the plant with a systemic fungicide with thiophanate methyl as the active ingredient. Well proven Ridomil Gold Ridomil Gold.

Fungal infection of dendrobium Guignardia photo

Phyllostikoz starts on the leaves and pseudobulbs. Small yellow spots appear, gradually merge, darken. Leaf dries or rot.

Fusarium blotch affects not only leaves and pseudobulbs, but also flowers and buds. The causative agent of the disease is a fungus of the genus Fusarium. Gets into a plant through the damaged leaves, roots. Spores are very hardy, can live for a long time in the external environment, so they are easily transferred to clothing when caring for flowers. Lime disease is not fully successful even with the use of fungicides. Sick Dendrobium must be isolated from other, damaged tissue should be cut and disinfected sections. In spring or summer, a new substrate and a pot are prepared for the flower. Old must throw out.

Fungal infection on orchid Phyllosticta photo

A fungus of the genus Botryties provokes the development of gray rot, which is manifested by tiny watery spots on the flowers and buds.

Cercospora fungus on the dendrobium leaves turn yellow photo

Infection with cercospore first appears as a yellow spot on the underside of the leaf. Shortly after infection, the yellow area appears on the upper surface of the leaf. As the spots grow in irregular patterns, they become slightly sunken and necrotic, later becoming purplish-brown to purplish-black. These spots continue to grow in both round and shapeless patterns and may eventually cover the entire sheet. New fields of infection are still painted yellowish, and eventually the most severely infected leaves fall off the plant, especially where the infection begins near the base of the leaf.

Исключительно ослабленные растения поражаются Ботритисом. На листьях и псевдобульбах орхидейки формируются серые пятнышки. Causes of the disease: high humidity, low air temperature with low airing of the room, overfeeding with nitrogen, insufficient lighting. The diseased flower must be immediately isolated and treated with a fungicide.

Bacterial Dendrobium Orchid Rot

Bacterial rot must be treated with a systemic copper-based fungicide, for example, copper sulfate. Damaged parts must be cut and removed, and the remaining ground parts are treated with a fungicide 2-3 times with an interval of 10 days.

Erwinia chrysanthemi bacterial rot on dendrobium photo

This is a relatively new disease, can be brought with poor-quality water, manifests itself brownish spots, sometimes watery with a yellowish tinge. In some genera, the bacterial rot is translucent on the leaves, in other words, you can almost see through the leaf, and gradually the color becomes darker to black. As a preventive measure, it is best to spray the surrounding space and plants with a fungicide before and during wet weather. To control the disease on the plant itself, remove or cut the infected area from the leaf and treat it with a fungicide.

Pseudomonas bacterial rot on dendrobium

Treatment of Pseudomonas (Pseudomonas) involves the destruction of bacteria and the prevention of reinfection by eliminating localization in an environment where bacteria can persist and re-infect orchid. Localized infection on the leaves can be treated with hydrogen peroxide (H2O2), although, if possible, it is possible to remove infected leaf tissue under the infection.

Surface treatment means with chlorine in the composition will not be superfluous. It is very important to treat neighboring plants preventively, as this disease spreads quickly. Be sure to treat the fungicide not only the sick plant, but all its neighbors. The necessary environmental control is to increase the movement of air, it is forbidden to spray the leaves of plants for an extended period of time.

Dendrobium Pests

Most often, the Dendrobium is affected by a spider mite, aphids, thrips, shield, mealybug.

The thrips appear as bright spots on the upper surface of the leaf and flowers. They reproduce on the lower side of the leaf. Capable of creating whole colonies of bacteria. The leaves become a grayish-brown shade, silver shine. If the disease is neglected, they lose their color completely, eventually fall off.

Flags look like brown plaques. They suck from the leaf cellular juices. Leaves dry and fall off.

The whitefly is a midge, laying off greenish larvae on the inside of the leaf. Just suck the juices. Leaves turn yellow and fall off. It is not enough just to wash the whitefly with soapy water. It is important to treat the plant with insecticide several times in order to completely remove the pests.

What tools to use for pest control

To combat parasites use insecticides: Biotlin, Fitoverm, Vermitek, Aktara, Sunmite and others. In addition, it is necessary to raise the humidity around the flower, wash the leaves every two weeks with soapy water.

Prevention - the best way to protect, so you need to regularly ventilate the room, avoiding cold drafts. When setting the warm sunny weather, plants can be exposed to the open air.

Dendrobium: Signs and Superstitions

Orchids - the real talismans of any woman, help to develop talents, engage in creativity. In order for the plant to be good to the hostess, it is necessary to properly care for it, to prevent diseases, wilt. A flower can prolong and even return youth, health, good mood. It gives attractiveness, enhances all women's qualities, character traits.

Flower description

Most dendrobium belongs to epiphytic plants, like other orchids. They live on the trunks of trees, but they feed on their own. Translated from Greek, the dendrobium is translated as “growing on a tree”. To date, described more than 1000 species of dendrobium. Natural area of ​​their growth: The countries of Asia, New Guinea, India.

These flowers are suitable for content in greenhouses and city apartments. Flowering time depends on the species, but mostly in the spring. Inflorescence peculiar light pleasant aroma. Compared to other types of orchids, this is not such a whimsical plant.

On average, the dendrobium grows up to half a meter in height, but there are also larger specimens. The stem consists of cylindrical pseudobulb. The leaves are alternate, peduncles appear from their sinuses, on which from one to 4 flowers bloom. Color petals can be very different. White, lilac, yellow, pink dendrobiums can be one-color, or two-color, and even tricolor.

Dendrobium nobile (noble)

One of the most decorative types. Dendrobium nobile has fleshy, upright stems with a smooth and shiny surface. The height reaches half a meter or a bit more. Flowering begins in the second year of life with bright fragrant flowers. In hybrid varieties flowering occurs several times a year.

The flowers are large up to 10 cm in diameter, most often have a white edging. Petals elongated, with pointed tips. In its homeland in the Himalayas, dendrobium nobile grows on the slopes of mountains. Flower growers consider it unpretentious in the care. The minimum temperature of the content in winter is 15-16 degrees.

Throughout the year, he needs bright diffused light. In winter, this is achieved by using the backlight. A mixture of peat, moss and charcoal can be used as a substrate. After watering, the moisture should linger for some time in the substrate.

On a note! When watering try not to fall on young bulby, they are prone to decay.

Transplantation is carried out in the spring when the pot is fully filled with roots. Urgently plants are transplanted only in extreme cases, for example, when the substrate is damaged. Propagated by dividing the old tuber.

Dendrobium Moniliform

In the culture grows miniature, up to a maximum of 20 cm. We still have this rare and therefore expensive form. Most often, the flowers have a white-lilac color and smell very nice. With good care can bloom all year round. Each bulb has 1-2 inflorescences.

This kind of calm tolerates even direct sunlight. He is even recommended several hours a day of bright open sun. The view is not demanding of air humidity. A special substrate for orchids with a high permeability of air and moisture is suitable as a primer. The flower is watered by soaking 2-3 times a week.

Leaving after flowering

After flowering, the aerial part of orchids begins to grow rapidly, and children form. At that time increase the temperature and humidity in the room, plants regularly (once in 2 weeks) fed with fertilizer for orchids.

Active growth continues until the end of summer, all this time the old pseudobulbs are not removed - they provide additional nutrition for the younger children.

Dendrobium is very painful for a transplant, so it is performed. once in 2-3 years and only when necessary. For example, if the pot became very cramped, growth stopped, and new pseudobulbs hang over the edges of the tank, and in the case when the soil is salted.

To begin transplanting in the spring, after flowering and the beginning of active growth. Recommended completely remove the old soil from the rootsIn order to achieve this, the plant pot is soaked in water, then the swollen substrate is easily removed without residue.

Roots inspect, rotted, damaged areas cut, powdered cuts charcoal. You can not cauterize the wounds Zelenko and other preparations containing alcohol. Then the roots are dried for several hours.

The above-ground part of the plants is usually very massive, so you need to choose stable containers for planting. Most suitable heavy clay pots.

A quarter of the capacity is filled with drainage. Substrate poured into a hill, straighten the roots of orchids and gently fall asleep voids. It is better to place the plants in the center, without deepening the pseudobulb. If necessary, install the support.

The pots are left in a darkened room with a temperature of about 20 ° C.

Water the orchid 2-4 days after planting. Read more about orchid transplant here.

How to care for a dendrobium nobel orchid?

Epiphytic orchids need a rather poor and loose soil. The substrate is made from crushed pine bark, sphagnum moss and peat. Add to the mixture charcoal. It is important that the ground there was no calciumbecause most orchids do not tolerate it.

You can use the ready soil for epiphytic orchids.

Fit and shredded bark of conifers. In this case, put larger pieces on the bottom, upward - smaller ones. When adding a small amount peat mechanical properties of the substrate are improved, acidity is optimal for orchids.

For planting use conventional pots and hanging baskets of rails. The main thing is to provide good drainage, it must be at least of the height of the pot. To do this, a thick layer of broken brick or granite rubble is placed on the bottom of the tank. Expanded clay and limestone do not fitcontaining calcium.

A thick layer is put in the baskets. sphagnum.

Looks beautiful orchid, fixed on the snag. In this case, it can be placed in a special greenhouse with bromeliads.

In nature, the dendrobium nobile grows with very bright but diffused light. In the room, especially in winter, there is a catastrophic lack of light, therefore from May to September it is better to keep orchids on the east and west windows, and in the winter on the south windows.

From time to time the pot is turned, and on cold days it is removed from the window sill.

Types and varieties with white and pale pink flowers less demanding, if I may say so, to the lighting and with additional lighting, they grow quite well even in the north-east windows.

Plants with bright red, pink, yellow flowers It should be placed in the south-east, south-west, and in the winter and on the south windows, and at the same time use additional lighting.

  • If a too much light, the orchid continues to grow and grow pseudobulbs, but at the same time they will be smaller, which will further affect flowering.
  • With low light pseudobulbs grow thin and long, and in this case, as a rule, do not bloom.

The orchid quickly absorbs water only with sufficient illumination; therefore, when it is reduced, watering is also reduced.

Orchids are watered after the top layer of moss or substrate dries out. In the summer, 2-3 irrigations per week are required, and in winter the plants are kept in arid conditions.

In pots, plants are watered from above, and baskets and blocks are placed in water for 3-5 minutes.

Water for irrigation should be soft, best used. boiled, with a temperature of a few degrees above the air temperature.

From April to September, fertilizer is added to the water for orchids containing nitrogen, potassium and phosphorus in equal amounts. This should be done through two watering on the third.

Temperature conditions

Temperature affects a plant only when it receives a sufficient amount of light. With its lack of orchids will remain in a dormant state, even with increasing temperature.

At too high temperatures, water evaporation through the stomata on the leaves increases, and the roots do not have time to provide the plants with the right amount of moisture.

Therefore, in the heat it is necessary to increase the humidity in the room. To do this, place the pots on trays with water and pebbles or wet moss. The leaves are regularly sprayed.

To prevent the development of fungal diseases, the room is often ventilatedwhile avoiding cold drafts.

On warm sunny days, orchids feel good in the open air.

Content in winter

Active growth of orchids at home begins in the spring, when the illumination improves. At this time, increase watering and feed the plants with mineral fertilizers.

With enough lighting, irrigation and optimum temperature by October, orchids grow the maximum number of leaves and form normal pseudobulbs.

In the future, there are two options:

  1. In favorable conditions growth continues, flower stalks form,
  2. In adverse - the orchid falls asleep, the tips of the roots become dry. At this time, the plant is transferred to a cool (with a temperature not higher than 10 ° C) room and not watered. In its sleeping state, the orchid remains until the illumination increases.

Breeding kids

Dendrobium nobile breed division of adult specimens into several parts. At the same time, on each of them there should remain 2–3 pseudobulbs and a sufficient amount of roots.

The best breeding material is side shoots - the kids.

To stimulate their growth immediately after flowering they increase the humidity of the air and increase the nitrogen content in the soil. In such conditions, aerial roots develop faster.

It is possible to increase the air humidity in any way:

  • Put the plant in the greenhouse.
  • Place the pot in the pan with water.
  • Spray the leaves regularly with warm water.
  • Cover the orchid with a plastic bag.

After the roots reach 3-5 cm, the children are carefully separated from the mother plant along with a piece of the stem. This should be done with a sharp knife or scissors. Slices sprinkled crushed or activated carbon.

At the bottom of a small pot piled a layer of pebbles or broken bricks and half covered with substrate. Place a young plant and sprinkle the roots of the remaining soil, gently compacting it so as not to damage the fragile roots.

For greater stability, the seedling is tied to a peg or bamboo stick, securing it in an upright position. At the same time it is necessary to ensure that the growth point remained above the soil surface.

Until a noticeable growth of the aerial part begins, the substrate is kept in a moderately humid state. Later watered, like adult plants.

Transplantation and reproduction of orchids, video:

With a severe lack of light and improper watering, orchids sometimes start to grow horizontally.

If the leaves are sprayed at low temperatures with air, the moisture evaporates slowly, favorable conditions for the development of gray rot are created.

When an orchid does not bloom and at the same time looks weak and unhealthy, the reason is most likely in the wrong care. With a lack of light, plants also do not bloom, but they look normal.

Botanical description

Large genus, including different in structure, size, color types. Stems can be fusiform, cylindrical, reed. There are miniature varieties and tall plants up to two meters. Homes usually do not grow above 60 cm.

  • Roots. Aerial roots are well developed, covered with a velymen - a loose hygroscopic fabric that absorbs and accumulates moisture.
  • Leaves. A variety of forms - elliptical, oblong, narrow-lanceolate. Gather at the top or grow all over the stalk. There are species with dense succulent (store moisture) leaves.
  • Flowers Different colors, sizes, shapes, often with a pleasant aroma. A common symptom is that the base of the lip is folded around the column (intergrown stamens and pistil). Колонка короткая, от ее основания отходят боковые чашелистики.
  • Соцветия. Кистевидные, чаще многоцветковые. Happen straight and hanging, apical and lateral. Flowering lasts from two to eight weeks.

Interesting species

The most extensive genus among orchids. It includes about 2000 species, a lot of artificial hybrid varieties. The following varieties and varieties are recommended for growing dendrobium orchids at home.

  • Dendrobium King. A miniature, flowering variety. Stems hard, cylindrical, thickening at the base. Leaves of three to four pieces are concentrated at the top. Small flowers, but very fragrant. Inflorescence is a few-flowered brush. Colors range from white to deep purple.
  • Dendrobium Lindley. Stem - low pseudobulba oblong-rounded shape. On each pseudobulb one sheet is formed. Peduncles long, drooping. The flowers are golden, very fragrant.

Flower adaptation after purchase

How to care for a dendrobium orchid after purchase? Leaving the first week at a new location affects the future growth and condition of the plant. Orchids are sensitive to changing the situation. It will take a week or two to adapt the flower and the beginning of growth. Your task is to help him in this.

  • Quarantine. For two to four weeks, the dendrobium is set apart from the rest of the indoor plants. Choose a shaded, cool place. The room is ventilated daily.
  • Feeding. Fertilizers are not applied during the adaptation period, even if they are recommended by the seller in the store. The flower first needs maximum peace.
  • Watering. The first week they do not water the dendrobium, but they constantly monitor the condition of its leaves and pseudobulbs. If the substrate is completely dry, the leaves begin to wilder, you can slightly moisten the soil.
  • Pests. In the store you can not notice the initial stages of pest damage. Keeping dry during quarantine facilitates their detection. The appearance of a thin spider web, spots on the leaves - all this indicates the presence of insects. Once again, the flower is carefully examined and treated with insecticides.

Basic rules of care

It is believed that care for the dendrobium is easy. But this is only from the point of view of an experienced grower. Care for any orchid is specific. All varieties without exception need systematic, attentive, responsible care.

  • Lighting. Keep in good light, but protected from the sun. The best accommodation option is the south window. The rest of the windows require lighting. Put on the north window is contraindicated. In the spring with the onset of stable heat, you can take out the dendrobium to the loggia. Fresh air is good for him. The temperature at night should not fall below 7 ° C. The intensity of the light affects the color of the leaves. Dark green is a sign of a lack of light. If the light is too bright, they become light-green. Yellow leaves - a strong lack of light, dangerous to the plant.
  • Temperature. At the stage of active growth, the optimum daytime temperature is 25 ° C, nighttime - 20 ° C Daily temperature differential is required - without this, the dendrobium will not bloom. Heat above 30 ° C does not tolerate. In the autumn the temperature is reduced. Day should be about 20˚C, night - 10˚С.
  • Watering. Watering is abundant after complete drying of the soil. It is believed that it is correct to water the dendrobium by immersing the pot in a container with warm water for 10–15 minutes. After draining excess liquid, the flower is returned to its original place. With the advent of new leaves on the tops of sprouts, watering is temporarily suspended. Renew them only after the appearance of flower buds.
  • Humidity. Artificial humidification is required only in summer. In the heat, the dendrobium is sprayed from a small spray gun with warm soft water. In winter, spraying is unnecessary and even dangerous. High humidity in combination with cold leads to rotting of the roots.
  • Feeding. Fertilizers are applied from the beginning of flowering to the final formation of new shoots. Use mineral complexes for orchids. Fertilizers are diluted in water for irrigation. Sometimes it is useful to conduct foliar feeding by spraying. For the first and last feeding amount of fertilizer take half as much.
  • Priming. Universal soil mixtures are unsuitable for planting orchids. Dendrobium is planted in a mixture of peat, pieces of coniferous bark, birch coal and sphagnum moss. Pre-substrate sterilized - poured boiling water or calcined in the oven. Before adding to the mixture, the bark is soaked for two days, followed by washing in pure water.
  • Transfer. Dendrobium needs good reasons for transplanting orchids. He is very hard on her. Indications for transplantation - salinization of the substrate, turning it into dust, constraining the roots. Transplanted in late February or early March.

What is the reason for the lack of flowering

Dendrobium at home does not bloom in violation of the mode of maintenance. Irregular watering, pests, lack of daily fluctuations in temperature - all this has a bad effect on the formation of flower arrows and buds. The most common situations are.

  • Peduncle is not formed. Instead, new babies are actively appearing. The reason is a lack of light and high air temperature.
  • No flowering more than one and a half years. Dendrobium suffers from a constant lack of light or is contained without a period of rest. Coolness and daily temperature fluctuations are the main factors for successful budding of flower buds.
  • Flowers bloom, but immediately dry. The main causes are pest damage, excess moisture and heat.

Features care after flowering

The further development of the plant depends on the proper care of the dendrobium orchid after flowering. Do not rush to cut the peduncle with pseudobulb - first assess their condition.

Remove only dried pseudobulbs. A weak but lively pseudobulb may bloom again. Flowering can be stimulated - reduce watering and spraying, put the dendrobium in a cool place. With the advent of sprouts resume watering. When the sprouts get stronger, the technique is repeated - reduce watering and keep cool for the formation of flower buds. Re-watering intensifies with the appearance of buds.

Dried pseudobulbs are cut with a sharp, previously disinfected knife. Sections are treated with charcoal powder, sulfur or powdered with ground cinnamon. Some florists prefer to use garden pitch.

Features orchid dendrobium

Dendrobium orchids are predominantly epiphytes, not living in nature on the ground, but leading to existence, attached to the trunks, roots and branches of woody plants. Orchids of this genus belong to the sympodial type, that is, they form new leaf rosettes on rhizomes at the base of the old one.

The shoots of the dendrobium, at first erect, and with continued growth become lodging, covered with elliptical or linear leaves. During its life, which lasts from 2 to 4 years, the pseudobulb of the dendrobium reaches a length of one and a half meters, and then becomes bare and, having given its daughter sockets, dies.

In the sinuses of alternately growing foliage, buds of inflorescences or new shoots are formed, which are easily used when grafting for breeding Denbrobium orchids. The flowers are combined in high racemes, on which, depending on the type and maturity of the plant, from 5 to 20 corolla can unfold.

The shape of orchid flowers Dendrobium Nobile and their unique palette does not leave indifferent even the experts of this culture. Today you can find and grow plants in the room with white, lilac, orange and even variegated flowers. That is why this kind is the most valuable for flower growers all over the world.

What are the maintenance conditions for orchid derderbium nobile and home care for representatives of this unique genus?

Dendrobium: home care for the orchid

In order for the plant to bloom profusely and grow, giving new pseudobulbs, it must feel constant care and support from the grower. Dendrobium orchid care includes:

  • regular watering
  • top dressing
  • irrigation and showers on especially hot days.

Especially frequent watering plant receives throughout the entire period of flowering and growth. But here we must take into account that the constant presence in a wet environment for the roots of an orchid is unacceptable. Substratum between watering should dry out.

The best way to water is to immerse in filtered water, the temperature of which is a couple degrees warmer than the surrounding air. At the same time, wetting of the soil can be combined with dressings by adding liquid fertilizer for the orchid to the water.

It is possible to stimulate flowering by regulating the watering and nutrient supply to the roots. With the end of the growing season, watering is reduced, and fertilizing is completely canceled until flower buds appear on the plant again. The early resumption of dendrobium, which is customary for summer care of an orchid, does not activate the development of buds, but the growth of daughter outlets.

Dendrobium orchid transplantation and reproduction

Like other indoor orchids, the dendrobium is not very good at frequent transplants, so this procedure is carried out no more than 2–3 years later.

Dendrobium orchid transplantation is needed for several reasons:

  • with the growth of roots pushing the substrate out of the pot,
  • if rot or pests are detected,
  • with deterioration in quality and decomposition of the substrate inside the container.

The plant needs a special coarse-grained soil, which can be bought in a store or made independently of fine expanded clay, crushed moss, coconut fiber, charcoal and bark of coniferous trees.

Transplanting is an excellent reason for vegetative propagation of dendrobium orchids. You can get young plants in two ways:

  • using daughter rosettes for landing, which are formed on top of an adult pseudobulb,
  • receiving sprouts from lateral dormant buds chopped on the cuttings of the shoot.

If the orchid is large enough, you can divide the bush. But at the same time in each new plant leave at least three juicy pseudobulb. Older shoots that have lost their elasticity form roots worse and take longer to acclimatize.

For cuttings, orchid denbrobium and small rosettes rooted in the substrate are suitable for greenhouse conditions. In the bright light, in the warmth of the plant quickly form the roots for independent living. It is possible to replant shoots into the soil when several rhizomes with a length of 3 to 5 cm appear.

Home transplant

This operation seriously injures the dendrobium, so it is recommended to transplant plants no more than once every two to three years. In principle, it is worth carrying out this operation only if there is an urgent need for it. Examples of such situations may be when in the tank in which the dendrobium grows, it no longer has enough space. the plant has ceased to gain mass, emerging pseudobulbs hang over the edges of the pot, there are signs of soil salinization.

  • The best time for reproduction is spring, the moment after flowering or at the beginning of active growth. The roots of transplanted plants must be cleaned from the old soil. For this, the plant pot needs to be thoroughly moistened, then afterwards it will be possible to remove the existing substrate without any problems,
  • Before planting, it is necessary to inspect the roots: if rotted or damaged areas are found, they should be removed and the cuts processed with charcoal. It is forbidden to use for this purpose brilliant green or other preparations, as a part of which alcohol is present. After that, you need to give the roots to dry for several hours,
  • orchid feels best in cramped tanks. For this, pots are selected so that the thickness of the substrate between the roots and the walls should be no more than 2 cm.
  • in the process of growth, the aerial part of the orchid becomes large in size, therefore it is recommended to plant it in stable containers. The best option is heavy clay pots,
  • picking up a suitable breeding tank, drainage is placed on it in ¼ of the volume. Further, it is filled with substrate to form a slide. After this, an orchid is being prepared for transplanting: its roots need to be flattened, and then the plant is placed in the center. Care must be taken to ensure that pseudobulbs remain on the surface. In some cases, support may be required to ensure good stability,
  • after planting with a view to breeding orchid containers should be kept in a dark place, the temperature should be approximately 20 degrees Celsius. After 2-4 days, you can begin to conduct watering.

How to care for a dendrobium orchid?

Photos of plants look beautiful because they were proper care is provided. This moment just need to pay maximum attention.

Epiphytic orchids feel better on soils that have a loose structure and do not contain a lot of nutrients. A mixture based on crushed pine bark, sphagnum moss and peat is used as a soil substrate. It is also necessary to add charcoal. The soil mixture used for planting orchids must be free of calcium. This is due to the fact that many types of orchids react negatively to this element.

Can also be used as a substrate. chopped bark of conifers. Fill it with capacity should be as follows: at the bottom you need to put larger pieces, and in the upper part have smaller ones. Positive effect on the quality of the substrate is the presence of a small amount of peat, which improves its mechanical properties. As a result, the soil for orchids acquires the best indicators of acidity.

The substrate prepared for use must be disinfected. To do this, it is necessary to shed boiling water and let stand for 10-15 minutes. Then wait until it dries.

When breeding orchids dendrobium at home can be planted in ordinary pots or hanging baskets of rails. However, in any case, they will need good drainage, which should be at least 1/4 of the height. To do this, use broken brick or granite rubble, laying it in a thick layer. But the use of clay and limestone, which is rich in calcium, is not recommended.

Before planting in the basket must be added thick layer of sphagnum. Plants that grow on a snake support look more decorative.

Under natural conditions, dendrobium nobile feels good only if it is provided with bright and diffused lighting. Under room conditions, this becomes a problem, especially in winter, when there is a severe lack of lighting. For this reason, to create the most favorable conditions, it is recommended to grow orchids from May to September on the windows facing the west and east, and in winter they should be transferred to the south.

During the care periodically, you need to rotate the pot so that all parts of the dendrobium got enough light. In the case of approaching cold weather, it is necessary to remove them away from the window sill.

Хорошо расти орхидея дендробиум сможет, если будет обеспечена в течение дня светом в достаточном количестве. Обычно оптимальной является продолжительность светового дня 10-15 часов. В зимнее время дефицит освещения можно устранить путем подсвечивания специальными лампами.

  • сорта орхидей, имеющие белые и бледно-розовые цветы, гораздо лучше переносят недостаток освещения. Therefore, subject to additional lighting, they will feel good on the windows, located on the northeast side,
  • If you are growing dendrobium orchids with bright red, pink, yellow flowers, then it is better to keep them on the windows facing south-east and south-west. With the advent of winter, they are transferred to the south side, not forgetting the creation of additional illumination for them.

By providing too much light to the plants, you will ensure that the dendrobium orchid will actively gain weight, forming pseudobulbs, which at the same time will not grow large, and this will negatively affect flowering.

With a lack of illumination, the pseudobulbs will be thin and long, while flowering usually does not occur.

In order for an orchid to absorb all the water used for watering, it needs to provide a sufficient amount of light. Therefore, you need to pay attention to this moment and regulate the rate of watering.

Dendrobium orchid watering

Home care means choosing the right moment for watering. The signal for the start of watering plants is the drying of the top layer of moss or substrate. In the summer it is enough to hold two or three times a week. With the onset of winter watering should be minimal.

  • If the dendrobium orchid grows in pots, then while leaving the water is poured from above. If they are in baskets or blocks, they need to be put in water for 3-5 minutes.
  • Watering plants is recommended soft, even boiled water, which should have a temperature of several degrees above room temperature.
  • In the period from April to September, watering should be combined with dressing. To this end, fertilizers rich in nitrogen, potassium and phosphorus are spread in equal proportions in the water prepared for irrigation. The frequency of such irrigation should be small - every two irrigations.

Conclusion

Growing a dendrobium orchid at home is a rather laborious task. However, the desire to enjoy the flowering of this plant very few people stop. In order for the orchid to enter the phase of active growth in spring, it is necessary to create favorable conditions for it even in winter. For this you need maintain a temperature not higher than 10 degrees and completely eliminate watering.

The dendrobium nobile requires even more attention during the spring period when it begins to actively gain green mass. In addition to maintaining the optimum temperature, during care it must be provided with the necessary amount of moisture and regular feeding. It is also important to ensure that indoors there were no cold snaps. Compliance with these conditions allows in October to get well-developed orchid bushes.

Orchid Dendrobium care at home

In order for a dendrobium orchid to develop normally and delight a grower with its decorative effect, she should provide a microclimate similar to the one in which she grows in the wild.

From what place the gardener chooses for the orchid, will depend on its growth and flowering. It is best to prefer the northeast or north window sill. If the orchid grows on the north window, in the winter it will need to illuminate the fitolamp, thus extending the daylight hours.

In the summer, you should not put a flower on the southern window-sill, since not only will direct sunlight fall on it, but also the temperature regime, at times exceeds the one needed by the plant. This variety of orchids, unlike the rest, should not be rotated around its axis, as this will have a bad effect on flowering.

Dendrobium orchid is a light-loving plant. Therefore, the place chosen for it should be well illuminated, but it should be ensured that the light was diffused. At hit on leaves of direct sunshine, on them burns will appear. In winter and autumn, to extend the daylight hours to 12 hours, you can use fitolampy. If the plant has little light, it will cease to develop.

During the growing season with the onset of spring, the orchid begins to form young shoots, as well as accumulate moisture and substances necessary for growth and development. For a culture to develop well, it must create appropriate temperature conditions.

In the spring they should be from +20 to +24, and in the summer from +24 to +27. If the temperature rises or falls, the plant starts to hurt, and if the temperature rises to + 30, then kids will start forming instead of buds. To stimulate flowering, it is necessary to create temperature differences of 5 degrees between day and night.

Since orchids are home to tropical rainforests, the humidity in the room should not be below 60%. If the humidity is low, the crop should be sprayed daily or humidified using air.

Dendrobium Orchid Ground

The main ingredient of the substrate for the plant is pine bark. Its pieces should be small so that they can dry out faster after watering. Sphagnum and peat is better not to add, as these ingredients retain moisture, which leads to decay of the root system. Instead, add a handful of charcoal.

For drainage, you can use foam or pebbles. Expanded clay is not suitable, as it accumulates salts from water, which adversely affect the health of the plant.

Before planting an orchid in the substrate, it should be disinfected by spilling with boiling water and allowing it to stand until dry, after which the soil can be used for its intended purpose.

Dendrobium pot for orchids

The root system in the pot should be a little cramped. If it is too spacious, then the bark will absorb more moisture, which means that soon the root system will begin to rot.

The pot must be high enough to fit both the drainage and the counterweight. Since the dendrobium is a large and tall plant, it is necessary to put a counterweight on the bottom of the tank in order to avoid dropping the pot on its side.

At the bottom and in the side walls there should be drainage holes that facilitate the outflow of moisture and ventilation. Since the root system of an orchid prefers a constant temperature, it is best to choose a pot of clay, which will help to maintain the optimum temperature.

Dendrobium orchid transplant

Since the dendrobium tolerates transplantation very poorly, this procedure should be done every three years if:

  • The substrate began to decompose or becomes dense,
  • The soil was acidified,
  • The root system suffered as a result of waterlogging,
  • It's time to transplant.

Pot for transplanting plants need to take earthen, 4 centimeters more than the previous one. When the plant is taken out of the pot, it should be placed in a solution of succinic acid, preparing in a ratio of 1 tablet per 1 liter of water.

After the culture has lain in the solution for 20 minutes, its roots will become greenish-milky. Then the plant must be removed and put on a paper towel to dry for 30 minutes.

Next, you should take a pot, put drainage on the bottom and carefully place an orchid in it so that the old pseudobulbs are closer to the walls of the pot. The root neck of the plant should be left on the surface, the roots spread, and the gaps between them should be filled with the substrate, slightly pressing it with the palm on top.

Watering is carried out a week after transplantation, after the wounds healed during the procedure will heal on the root system.

Dendrobium orchid fertilizer

Dendrobium should be fertilized from April to September twice a month. Top dressing can be diluted in water for watering or dissolved in a liquid for spraying. Dilute the solution should be in a concentration of two times less than that indicated on the package.

During flowering, the plant is not fertilized. Nutrients should be introduced only if new pseudobulbs grow or bloom during flowering. If the orchid is sick or it was attacked by pests, the application of fertilizing should be stopped until full recovery.

Dendrobium orchid bloom

Each orchid species has its time of flowering, but usually it falls in winter and spring. Dendrobium bloom for eight to twelve weeks.

The size and color of the orchids will also depend on the type of culture. Most often flowers have pink, yellow, violet, orange, red and two-color shades.

Virtually all varieties of dendrobium exude a subtle, pleasant aroma during flowering.

Dendrobium orchid pruning

It is necessary to cut off the pseudobulb only when it dries completely, giving the orchid all the necessary substances and liquid. If there are still buds on the peduncle, then it will surely bloom, but this will take time.

You can remove dried or yellowed leaves, as well as faded buds. It is necessary to maintain the decorative appearance of the culture.

Rest period in orchid dendrobium

After flowering, the orchid begins a period of rest, so the plant should be moved to a cool room so that it rests until the next growing season. During the day, the temperature regime should be within 16-20 degrees, and at night within 10-12.

Watering culture should be reduced to a minimum, and after a while, stop altogether. Feeding also need to stop making. If the pseudobulbs begin to wrinkle, you can lightly spray the substrate in the pot.

На протяжении периода спячки следует внимательно следить за растением, и как только оно начнет из нее выходить, его следует переместить в привычную среду и продолжить ухаживать за орхидеей в обычном режиме. Время периода спячки и выхода из нее, будет зависеть от разновидности дендробиума.

Dendrobium reproduction by cuttings

Dendrobium is propagated only by vegetative means. Seed method is not used because of its complexity and very slow growth of seedlings. Therefore, flower growers prefer to propagate dendrobium orchid cuttings.

In order to propagate the plant, one should separate the whole pseudobulb and cut it into pieces of 10 centimeters, sprinkle the slices with crushed coal and dry it in air. It is best to root the cuttings in wet moss by inserting them into a container with sphagnum and covering it with a film.

The container with the cuttings should be kept in a warm and lighted place, airing it daily and moistening the moss with a spray bottle. After two months, when planting material has taken root, plants can be transplanted to a permanent place of growth. Young orchids will bloom in three years.

Orchid Dendrobium breeding babies

The formation of babies occurs in the upper part of the pseudobulb. After some time, they begin to form their own root system. When the roots reach a length of 5 centimeters, the children are carefully cut with a sharp knife along with the roots, dried and rooted in pine bark at a temperature of +25 degrees and a humidity of at least 60%.

You should also place the pot with the children in a sunny and warm place so that they grow better. Young orchids begin to bloom in two years.

Dendrobium reproduction by bush division

Orchid can be propagated with the help of bush division. However, for this method it is necessary to take a mother plant that has already reached the age of four years and has from four to six pseudobulbs. The division is always combined with transplant.

Before dividing the plant, the root system needs to be removed from the pot, freed from the ground and cut into several cleats, on which a pair of pseudobulb with the root system should remain. After dividing the bush sections need to be treated with coal and planting plants in pots.

The orchid tolerates division badly. Therefore, for breeding is best to use the branch of the kids. Thus, the plant will receive a minimum of injuries, and kids quickly take root and begin to grow.

Diseases and pests

With proper care of the dendrobium, the grower may not be afraid of diseases and pests, but if the rules are violated, the plant may undergo various problems that affect its health.

Most often on the orchid attacks aphid, spider mite, scalefish and mealybugthat feed on the juice of leaf plates, stems and peduncles. These dangerous pests can be eliminated by spraying the culture with Actellic.

With improper watering, orchid can undergo ailments of fungal etiology. Excessive moistening of the substrate leads to such a serious malaise as root rot. Save the plant in this case will be difficult, but still try to do it, you need.

For this purpose, it should be transplanted into a new pot with a fresh substrate, after removing the damaged roots, drying them and treating with charcoal. Watering reanimated orchids should be carried out on the tenth day after the procedure.

Problems growing orchid dendrobium

Various problems encountered by orchid growers are most often caused by improper care of the crop.

The most common ones are:

  • No flowering - Dendrobium does not bloom due to lack of sun, lack of rest or overfeeding with nitrogen fertilizers. By eliminating the above reasons, you can achieve the appearance of buds and luxurious flowering in the future.
  • Twisting leaves - the twisting of the leaf plates is observed when the air is dry and the temperature rises above the allowable one. Eliminating these causes, the problem with the leaves resolved on their own.
  • Sticky sheet plates - leaves become sticky as a result of orchid damage by the shield. Insects can be destroyed by treating the orchid with the Aktellik insecticide.
  • Forming babies instead of buds - this problem arises as a result of non-compliance with the rules of care during the period of rest, as well as during the wrong irrigation regime. Having identified errors in the care of the plant and eliminating them, the florist will begin to notice the appearance of buds, which will turn into luxurious inflorescences with a pleasant aroma.
  • Yellowing and leaf fall - leaves begin to turn yellow and wither as a result of infection of the plant with root rot due to overwetting of the soil. In this case, the transplant will help to save the orchid, with the preliminary removal of spoiled roots.
  • No growth - Orchid stops growing with a lack of fertilizer or low temperature indicators of its content. Having made the necessary additional feeding and adjusting the temperature, the florist will begin to notice how the culture has gone up.
  • Blacking sheet plates - black spots appear as a result of the defeat of the dendrobium by ailments of viral etiology, developing at low temperatures of maintenance and improper care. Normalizing the microclimate, and removing the damaged leaf plates, the culture can be saved.
  • Swoop on leaves - plaque on the leaf plates appears as a result of the infection of the orchid with a spider mite, which covers the leaves with a white sticky web. You can eliminate the pest by treating the plant with the insecticide "Aktellik"
  • Drying sheet plates - leaves can dry out if the orchid is damaged by a spider mite or due to lack of moisture. Drying can be eliminated by treating the orchid with the Aktellik insecticide or by adjusting the irrigation regime.

Breeding methods

Dendrobium orchid can be propagated only vegetatively. Seed propagation is usually not used due to slow growth. Getting seed from your plant is difficult and useless. Homemade seeds of hybrid varieties do not carry the characteristics of the parent plant variety. Use three methods.

  1. Children. Children form at the top of the pseudobulb. Over time, they let their own roots. When their length reaches 5 cm, the dendrobium baby is carefully cut off with a sharp knife along with the roots. Before planting, the appendix is ​​dried for several days in a shaded, well ventilated place. Rooted in the shallow pine bark. Conditions for successful rooting - bright light, air humidity 70%, temperature 20-25˚С. Dendrobium from babies bloom two years later.
  2. Cuttings. The whole pseudobulb is separated, cut into 10 cm pieces. Cuts are powdered with coal powder, and the cuttings are dried in fresh air. Root better in sphagnum. A container with cuttings on top is covered with a film to create greenhouse conditions. Keep at ambient light, warm, air regularly. Moss, if necessary, moistened with a spray. After two months, transplanted to a permanent place. The first bloom occurs in two to four years.
  3. The division of the bush. You can plant dendrobium at home by dividing the mother plant. It must meet a number of requirements - the age of four years, good conditions of detention, the presence of six or more pseudobulb. The division is combined with transplant. The roots are freed from the substrate, cut with a sharp knife. In the delenke leave two to three pseudobulbs with roots. Sections are treated with cinnamon or coal powder and planted.

Diseases and possible problems of growing

Most of the difficulties are the result of improper growing conditions. The plant weakens, resistance to diseases and pests decreases. The table shows the signs to determine the error of care or the presence of pests.

Table - Problems faced by flower growers when growing dendrobium orchids, and their possible causes

Dendrobium is beautiful

Very fragrant variety with elongated stems. The leaves are located at the top. Flowering occurs in spring and early autumn. Small flowers, but very fragrant. Against the white petals, a yellow lip and a red center stand out in contrast. The rest period is twice a year - in winter and early summer. Grow this species preferably in blocks. Orchid loves the sun's rays and fresh air.

Dendrobium primrose

Orchid with lots of leaves and an unusual color of flowers. Around the yellow-white lips are purple stripes, and the petals themselves are pale lilac. In nature, the variety lives in Southeast Asia. From the bright sun leaves get burned, shading is required. Flowering occurs at the end of winter - the beginning of spring. The plant is watered plentifully, twice a week. In winter, it is desirable to organize additional lighting. The rest - the standard requirements for dendrobium.

Dendrobium fringed

It stands out among other dendrobiums for its size. His specimens often grow to 1.5 meters, sometimes higher. The elongated leaves grow in two rows. On one peduncle can be up to 15 flowers of medium size. May bloom throughout the year, in spring there is a peak of flowering. The flowers are kept on the plant for a week and a half, but the flowering can be called abundant.

He likes daytime and nighttime temperatures, in summer the maximum daytime temperature is about 30 degrees, in winter it is preferable to maintain it at 20 degrees. It is suitable average illumination. During the growth period, watering should be abundant. In winter, arrange a little drying between watering. You can grow both on the block and in the substrate. Transplanted when the roots are crowded in the pot.

Dendrobium long-horned

The species is characterized by the presence of rare pointed leaves. At home we are quite rare. It blooms in the spring months, flowering lasts about 3 weeks. This orchid can be attributed to miniature species - it grows up to 25 cm, but at the same time has relatively large 6-centimeter flowers. During the period of active growth it needs abundant watering and a lot of light. In the cold season, the substrate is watered less and dry out. In general, care requirements are standard for orchids.

Humidity and air temperature

The most common types of dendrobium require a dormant period in winter. Therefore, the temperature content in the winter and summer will be different. In the summer months, the dendrobium contains at a temperature of 22-28 degrees, in winter the values ​​should be 17-20 degrees with a significant reduction in watering.

On a note! During the rest period, watering can be replaced by spraying the substrate. Like other orchids, dendrobium requires high humidity. New hybrid varieties are less sensitive to this.

To increase the humidity using traditional methods:

  • the use of a humidifier
  • spraying plant leaves,
  • pallets with wet pebbles or expanded clay, placed on the windowsill.

It is necessary to spray the leaves in the morning and evening hours, when direct sunlight does not fall on the plant. Refracted by water droplets, the sun's rays can cause burns.

In our climate zone in the summer, the dendrobium may suffer from an excess of sunlight, and in the winter from a lack of light. If the illumination for the dendrobium is insufficient, its shoots are bent, a small number of flower buds are laid. For most species, in the summer months, shading is organized, and in winter they turn on the backlight so that daylight lasts at least 12 hours.

For illumination, a fluorescent lamp or a special fitolamp will be suitable. In spring and summer, it is better to rearrange the pots with plants to the western or eastern windows, and in winter to transfer them to the southern window-sill.

During the active growing season, the dendrobium needs abundant watering, on average 2 times a week. Between watering the ground in the pot should be completely dry. Drying rate depends on pot size and room temperature. Excess moisture from the pallet after watering must be removed, the root system of dendrobium does not tolerate overmoistening. Use need soft slightly warm water. During the rest period, watering should be minimal.

It is best to water the dendrobium by soaking at the same time shedding the top of the watering can. To do this, put the pot in a vessel with water for 20-30 minutes, the larger the pot, the longer should be the time of soaking. After that, the excess water is drained and the plant is returned to the window sill. If the room is cool, you need to wipe the leaves' sinuses with a napkin, otherwise their rotting is possible.

For those who have quality water from the tap, you can water the dendrobium from the shower head for a few minutes. This method is good because it allows you to remove from the substrate salts, harmful impurities and excess fertilizer. But, if water is chlorinated or it is too hard, it is better not to use it.

Selection of pot and soil, pots for orchids

It is better to grow dendrobiums using plastic pots; they can be both transparent and opaque. In a transparent pot there is an opportunity to track the state of the root system, therefore for beginners they are preferable. Glass or ceramic vessels can lead to supercooling of roots, which is undesirable for a tropical orchid.

In addition, a method of disembarking in plastic or wooden baskets or on a block is suitable. There should be a lot of drainage holes in the pot, if it is only one, make additional holes with a soldering iron or drill. Do not use pot-shaped pot pots. The roots of the dendrobium are very fragile, it will be impossible to remove them during transplanting without damage from such a pot.

On a note! Plant dendrobium in pots without a drainage hole is impossible. Its roots need free access of air and do not tolerate stagnant water.

As a substrate for dendrobium, you can use only one pine bark. The rule here is that the larger the plant and its roots, the larger the pieces of bark should be. Some add sphagnum to it to increase the water capacity of the soil, but in this case it must be taken into account that watering will be required less often.

Add pieces of charcoal to this substrate to prevent possible decay. Activated carbon is not suitable for these purposes, as it crumbles when wet. If you have to use purchased orchid soil for planting dendrobiums, be careful with watering, as in this substrate peat and moss particles are added for moisture capacity.

Fertilizer, dressing

Due to the fact that the roots of the dendrobium have an increased sensitivity, the fertilizer for it is diluted by half, even if it is a specialized dressing for orchids. Those dendrobiums that do not have a pronounced dormant period are fed monthly with a complex fertilizer containing potassium and phosphorus. Those varieties that you send for wintering should be fertilized two or three times a month with nitrogen fertilizer. During the rest period they are not fertilized.

Succinic acid for orchids

Succinic acid for orchids plays the role of a biostimulant. The substance is organic, absolutely non-toxic. Yantark increases resistance to the effects of stress, adverse conditions, helps in recovery after transplantation or illness. A solution of succinic acid can be bought in a flower shop, where it is sold as a spray, or you can make it yourself by dissolving one tablet of succinic acid in 1 liter of water. The prepared solution keeps useful properties within 3 days.

Succinic acid is used to process all parts of the plant:

  • you can soak the seeds in it,
  • spill at the root,
  • spray leaves.

On a note! Succinic acid is not a substitute for fertilizers, but is considered only an addition to them.

How to prune an orchid

Not everyone knows what to do with the dendrobium flower arrow after flowering. Is it worth it to cut or not? Pseudobulba needs to be removed if you see it drying out. To do this, use a sharp disinfected knife. If there are green buds on the bulb, leave it on the plant, it may still bloom.

It is necessary to remove the pseudobulb when it becomes completely lifeless, transferring all the accumulated nutrients to the plant. After that, you need to put a pot of orchids in a cool place and wait for the emergence of new shoots.

What is necessary to provide a beautiful dendrobium for its flowering?

A necessary condition for the flowering of dendrobium is proper wintering. The plant is kept in a cool, bright room at a temperature of 12-15 degrees throughout the winter months. In late winter or early spring, the dendrobium blooms. If flowering is delayed, the plant must be fed. Then buds will surely appear on it, and then luxurious fragrant flowers will appear.

Orchid bloomed, what to do

If the orchid brought from the store has faded, but the ground is still in good condition - there is no need to disturb the plant with a transplant. If the orchid that lives in your house has blossomed, then after flowering, as a rule, the growth of fresh shoots begins. To the plant was not crowded in the old pot, with the beginning of growth it is transplanted into a new container. Wait before the new bulbs grow to a height of 10 cm. As we already wrote above, if only the top of the pseudobulb has blossomed, then the flower arrow is not completely cut off, perhaps dormant buds will wake up on it.

Why does not bloom

In terms of flowering, dendrobiums are considered capricious plants. This reputation is due to the fact that they need a number of conditions for flowering. В зависимости от вида дендробиум подразделяют на 6 температурных групп, каждая из которых требует своей температуры выращивания. Поэтому необходимо уточнить в специальной литературе или в интернете, какого содержания требует именно ваш дендробиум и придерживаться его.Affect flowering and other parameters. Orchid may not bloom due to improper watering or insufficient light. Create the necessary conditions for it and the buds will surely appear.

Dividing bush

The division of the bush is possible in the presence of an adult strong plant, which has at least 6 pseudobulbs. Usually this procedure is combined with a transplant. Maternal tuber is divided into several parts so that each of them contains at least 2 pseudobulbs or one young sprout and one pseudobulb. Each delenki at the same time must have its roots. Before cutting, all tools are processed, sections are sealed with garden pitch.

Diseases and their treatment

Dendrobium diseases can be of viral origin. Bright rings or oval spots can appear on the leaves of a flower, the color and shape of flowers change, they become ugly. Some viruses may even interfere with bud opening. It is impossible to cure such plants, they will only have to be thrown away.

Bacterial diseases they can appear on the dendrobium in the form of blotchiness and rot, often accompanied by fungal lesions. The diseased plant is isolated, cut out all the affected areas and smeared the wounds with brilliant green or any disinfectant solution. This should be done at the first sign of illness. The plant is quarantined. If there are no new spots, return to their place. Bacterial rot is more dangerous because of its rapid development, it is necessary to act with it without delay.

Fungal diseases make up the largest group, in part they are provoked by inappropriate conditions of detention, under which fungal spores begin to actively develop. These diseases are manifested by the appearance of dark and brown spots, a gun. Treated with fungicides according to the instructions.

Sometimes a painful condition can be triggered by improper care.

Why leaves turn yellow

Causes of yellowing leaves may be natural. So the dendrobium prepares for the next life cycle after flowering. Following this, the plant begins to grow new shoots and rhizomes. Other factors can affect improper watering, nutritional deficiencies. If the leaf is not completely yellow, and there are yellow spots on it - it can be caused with sunburn.

The most frequent pests on dendrobium: thrips, aphids, spider mites. Their appearance can be triggered by increased dryness of the air. For prophylaxis, treat the leaves of the dendrobium twice a month with soapy water. You can remove pests mechanically by collecting them from the leaves with a damp cotton pad. If the insects did multiply, treat them with an atellic.
