Orchid Dendrobium Nobile considered the most popular variety among decorative flowers. In its natural environment, the Dendrobium nobile is found in China, Indonesia, Africa and the Himalayas - that is, in regions with a fairly temperate climate. This beautiful orchid, which blooms for months, will be a wonderful decoration for any home.
So what conditions need to be provided for Dendrobium Nobile flowering at home?
Description of the species
Orchid Dendrobium Nobile (Dendrobium nobile) is a perennial herb that belongs to the orchid family. The common names of a plant consist, as a rule, of the word Dendrobium with an adjective added to it:
- noble and so on
A large number of names is also the word "nobilis", which is a set of values translated from the Latin language.
The name Orchid Dendrobium Nobile received its name from the word "dendron"that in Greek means"tree"and" bium "- that is,"a life", the result was an interesting epiphyte "he who lives in a tree". In today's article we will cover the topic of caring for Dendrobium Nobile at home. This flower is very simple in maintenance and care, so if you are a beginner gardener and you are madly in love with orchids, this is your choice. Dendrobium tends to absorb formaldehyde, which helps to clean the air in the apartment.
Habitat and distribution
Dendrobium - a large genus of orchidswhich consists of 1200 different species. The genus originated from a variety of habitats. For the most part this is:
- New Zealand,
- New Guinea,
- Solomon islands,
- Southeast and East Asia.
Orchid species like lithophytes and epiphytes are plants that live on stony surfaces. The plants have adapted to the widest range of habitats: from lowland tropical forests to the high altitudes of the Himalayas and even to the very dry climate of the Australian desert. Dendrobium nobile is one of the most popular indoor orchids, the beauty of which bloom is beyond words.
The dendrobium noble is a sympodial orchid forming a pseudobulb. At an early age, these pseudobulbs are erect, and as the flower matures, they wilt.
- Pseudobulb have yellow-green color, straight and narrow shape, reach a length of 1.2 meters, crowned with several leaves of a narrow shape (10 cm in length, 2 cm in width).
- After maturation, the pseudobulb turns yellow and discards all its leaves.
- Pseudobulb lives on average 2-4 years. On the tops of old pseudobulb formed new ones. One pseudobulb per life cycle can produce from 10 to 70 flowers reaching 6–9 cm in diameter.
The leaves have a linear or lanceolate form, formed, as a rule, in early autumn. The pseudobulba loses all its leaves at the end of spring, changing them to floral branching stems. Orchid bloom occurs in the period from January to March. On the sepals and petals there are wavy edges. The lip has a large and rounded shape with a base in the form of a tube. The color varies from dark purple to pink, but the lip always has a maroon spot in the center.
Dendrobium nobile orchid care at home has certain features. In order to better understand how to properly care for the plant, you should be aware that the development cycle of the indoor flower can be divided into 4 periods:
- Vegetation period. The plant at this time appear boring at the base of the old pseudobulb. As a rule, they are called "kids" and are actively used for plant reproduction.
- Growth period. During this period of life, young shoots grow to the size of old pseudobulb.
- Rest period. The houseplant at this time begins the laying of future flowers.
- Flowering period.
Now let's see what conditions are necessary orchids for abundant flowering and successful growth?
This type of orchid is very photophilous, but the plant should still be shaded from direct sunlight. Dendrobiums can be placed on the windows of the south-eastern and southern orientation, but this should be done in a small distance from the glass, and preferably behind a light curtain. In order for the plant to develop a uniform, and its trunk was even, a pot with a potted flower is recommended to be rotated sometimes.
During the summer period, the orchid is brought to fresh air. If the flower at this time does not receive enough light, then the flowering, most likely, will not have to wait, even if all the necessary wintering conditions were observed.
Attention should be paid to the green and succulent orchid leaves, which serve as a kind of indicator that the level of illumination is in order.
Dendrobium for successful growth is necessary to make the difference between day and night temperatures.
During the day, it should be at a level of 22-27 ° C, and at night should be not lower than 17 ° C and not higher than 20 ° C. Of the many advantages of an orchid, it should be noted that it is capable of tolerating temperatures of more than 30 ° C quite easily without any problems.
In the winter season, as in the summer, it is necessary to make night and day temperature drops, but the temperature in general is almost the same, the main thing is to make sure that the room where the orchid is located is not cooler than 20 ° C. Also, a sharp change in temperature (for example, at the beginning of the heating season) by more than 5 degrees is threatened by the fact that the flower will receive a serious share of stress. In order to minimize negative effects, you should prepare the plant for change. For example, add additional fertilizers to the substrate or reduce the number of waterings during the flowering period.
When a plant grows green mass and root system, it should be watered plentifully and often. Any subsequent moistening of the substrate should be done only after the surface of the soil dries.
A flower in its natural habitat usually grows right on the trees. The roots of the plant are in the hanging position, they dry out very quickly, they do not tolerate excessive waterlogging.
Watering a flower should be done by immersing the pot for 5 minutes in water at room temperature. As soon as the shoots of the flower are stalled in growth, the plant's hydration must be stopped. The plant in this period is usually also not fed. Care resumes immediately after the orchid begins to produce flower buds again, but not earlier. Delayed hydration and nutrition can stimulate the formation of babies and the growth of vegetative buds. Excess nutrients in the substrate will lead to the fact that the flower will begin to turn yellow shoots and leaves.
Dendrobium nobile does not require high humidity. This is because the orchid is kept cool in the winter and fresh air in the summer. Spraying the flower from the spray gun should be done only in summer on the hottest days.
Periodic application of fertilizing - part of the basic care at home for this exotics. The plant should be fertilized as soon as the first flower bud formations appear and until the young shoots fully develop. The first and last feeding is two times less than the recommended dose. For the dendrobium fertilizer, you should use a complex orchid feed, which you can easily buy at any flower shop.
Orchid should be transplanted only in the most extreme cases: if the plant is ill, when it is seriously necessary to change the old substrate to a new one (when the soil is infected) or if the flower becomes cramped in the old container. After the flowering period, the flower should be transplanted into an opaque new container that is about 3 cm larger than the previous one.
For this purpose, you can use the bark of the middle fraction from pine or spruce with the addition of sphagnum moss and wood hulled, crushed almost into powder.
Overgrown flowers should be divided into several parts and transplanted into separate containers. Each of the divided parts should have several pseudobulbs (preferably young). Very old pseudobulbs are recommended to be removed.
Leaving after flowering - features
The question of what to do with a dendrobium nobile orchid after flowering is of concern to many gardeners. Basically this question is asked by those who have just started growing this species. In fact, taking care of a dendrobium nobile after flowering at home is not a big deal. If an orchid that has just been purchased at a store has bloomed, then there is still nothing to do with it, since the store floor has not yet had time to become useless and can still be used for further cultivation of a houseplant.
However, if we are talking about an orchid that has been growing in your home for more than a year, then it will most likely be necessary to transplant a flower to a more fresh ground. It should pay attention to the condition in which the pseudobulb, which began to grow during flowering. With their full formation, you should start landing, otherwise you should wait a little longer.
Many growers also ask what to do with the pseudobulb, which has already faded. Perhaps the best to cut it? In order to give the correct answer to such a question one should know that the orchid has a pseudobulb that is an organ that performs storage functions. It also serves as a source of nutrition for new shoots, so it should not be cut off if it is in a completely healthy state.
It is necessary to remove only the damaged, diseased, withering and old shoots. They are carefully cut with sharp scissors at the base. It is recommended to treat the cut point with cinnamon powder or simply sprinkle with crushed coal.
Orchid reproduction also part of plant care. You can do this at home in two ways - cutting and pseudobulb division.
Pseudobulb division is most often used to transplant overgrown adult plants. Propagation by cuttings should be carried out as follows:
- Cut the old branches of the plant into pieces so that they have several internodes.
- We put the planting material in a mini-greenhouse or greenhouse on a wet sphagnum-moss.
- We provide cuttings further care, maintaining a stable temperature, which is in the range of 23-26 ° C.
With proper procedure, the child shoots will appear on the nodes in two or three weeks.
Young shoots, which already have leaves and roots, must be separated from cuttings and planted in separate pots with small fractional bark. This breeding method has brought success to many gardeners.
This is a very beautiful and tender plant is not resistant to pests. The main cause of almost any disease is improper care.
- Aphid, spider mite, scab, mealybug - all these are parasites, which with pleasure eat the sap of the plant. To use sparing drugs is the most effective way of getting rid of insects, and when running forms it is possible to process flowers repeatedly with chemical preparations (Aktara, Vertimek, etc.).
- Excessive hydration - the most common mistake of novice gardeners, after which various fungal diseases can appear. They lead to rotting of the root system and the stems of the plant. In this case, save the plant is unlikely to succeed. However, if a flower is transplanted to a new pot and soil in time, the plant can be reanimated by first removing all the stems and roots that had time to rot.
The main conditions for the successful cultivation of orchids Dendrobium Nobile remain correct reproduction and transplanting, as well as competent care. If you do everything right, the plant will have more than one year to delight you with its beauty and elegance.
Colors of modern hybrids quite diverse. There are:
- Lilac and shades of lilac varying degrees of brightness,
- And coral tones.
The lip of multi-colored hybrids is often contrastingly colored. Gentle transitions from white to lilac with a yellow core, and a variety of variations on the theme warm the heart.
Diameter, flower shape
Flowers with a diameter of 9 cm.
On one Dendrobium Nobile grows to several dozen flowers.
Often grow inflorescences 2-3 flowers each, and there may be 6-7 dozen of them!
Optimal conditions of detention
In second place - air humidity. Dry air is detrimental to the gentle tropical exotic. During the heating period, a humidifier or a wet-pebble pan must be used, which by no means touches the roots.
A viable plant can survive at temperatures ranging from 3̊ to 42̊.
Dendrobium will become the decoration and pride of the house only in conditions that are optimal for it. Life cycle period:
- To build green mass:
- Day - 24̊С-27̊С,
- Night - Not higher than 22̊С-24̊С.
- To stimulate flowering:
- Day - 24̊С-25̊С,
- Night - 24̊-25̊, optimally 18̊-20̊.
The difference between day and night temperatures is mandatory for those who want have a healthy plant in colors. It is not necessary to go beyond the boundaries of optimal temperatures of 16̊С-30̊С.
Watering and feeding
In the warm season, during the period of active growth of the plant, need more wateringthan in winter and autumn.
Should be given the soil is completely dry between irrigation, and for each specific room, the frequency of irrigation should be chosen empirically.
It should be watered with quality orchid, otherwise it will die.
On average, from the middle of spring to the beginning of autumn it is enough to water once or twice a week, and during the rest of the year no more than once every two weeks.
Very good immersion methodwhen the container with the plant is completely immersed in water. If you do not drain water from the pan, the roots may suffer from rot.
If the plant is green and fresh, the roots are clean and without rot, then watering optimally matched.
We use special fertilizer for orchids. The main feature of such solutions - they do not settle on the ground, do not accumulate and do not harm the roots:
- Fertilizer type:
- Potash phosphorus.
- Phase of the year:
- Green mass growth
- Bud formation.
- With the beginning of active growth, approximately March. Fertilizer is added to water for irrigation, through time,
- When the buds appear.
How to stimulate flowering?
Dendrobium Nobile lives in accordance with the annual development cycle, so stimulation will be effective in the spring, directly after the active growth phase:
- Illumination with phytolamp on cloudy days and complementing additional 4-5 hours every day,
- Spraying of succinic acid according to the instructions
- Apply cytokinin paste to the visible kidneys in the sinuses.
Cut off directly dried inflorescences.
Disease and pest prevention
- Quarantine. A new plant should be kept a month apart. This is enough time to reveal hidden problems - pests or diseases,
- Pests can relocate on the window sill from the street with the window open,
- Draft. It is necessary to locate the pot far away from the open pane, and to protect against overcooling of roots and leaves in the wind, there is a danger of decay,
- Cold window sill. In nature, cold is unknown to orchids, the roots must be insulated with a stand for the time of winter,
- Sufficient time between watering. The soil must dry out completely, this is the prevention of rot on the root system,
- The exact amount of fertilizer according to the instructions. An overfed plant may stop flowering, cracks may appear on the leaves. From the "hungry" flower can not wait for lush flowering.
- Bark of pine boiled, crushed to medium fraction,
- Crushed moss
For soil for orchids usually use pine bark.
Ready soil where all the components mixed in the right proportions, sold in a flower shop.
- Drainage - big holes,
- More than a couple of centimeters previous,
- If there are holes in the walls, it is wonderful,
- An adult plant is massive and heavy, the pot must fit and not give the plant tip over under its own weight. For young, straight and slender shoots the weight of the pot does not matter. With growth, the plant will still have to be replanted more than once.
Signs of needing a transplant
Dendrobium nobile "does not like" transplant.
It is worth moving to a new pot only for good reason:
- The old pot has become small,
- Young shoots are yellowed, or there are dark spots on the roots, and the plant needs help,
- Soil "worn out" - turned black, crumbled, does not "hold" the plant.
Methods of reproduction at home
You can cut the cuttings through some time after flowering, no later than a year. Cut the former flower stalks about 10 cm long. Cut the slices with powdered activated charcoal (more chalk comes up) and dry them.
Seedlings need to be rooted. A wide container is filled with sphagnum with moist moss, and cuttings are placed horizontally.
To create a wet microclimate covered with glass or filmand air for 5 minutes every day.
This method requires the use of a root former, for example epin.
In three weeks the roots will begin to appear, and when in two months the real pseudobulbs grow, you can transplant into the ground for orchids.
From the top of the plant cut off a young, new pseudobulb, on which there were no flower stalks. For rooting will suit the same capacity as for cuttings.
If you create a warm environment with constant high humidity in a few months there will be new socketsfrom which full-grown plants can develop.
When each new plant grows roots of sufficient length, you can set aside in a separate pot in the ground for orchids.
Scions, or kids regularly appear on a healthy plant. When a new shoot grows roots longer than 5 cm, it can be carefully separated and planted in the usual way, and in a couple of years you can admire the first flowering.
When the dormant period comes, some leaves may turn yellow in a natural way, they can be removed without serious consequences.
A serious reason to pay attention to the health of the plant - yellowing of young leaves at the top. In this case, should be transplanted to a new clean ground.
Some orchids do not tolerate transplanting in new soil and give yellowing of leaves.
Roots before transplanting need to be washed, leaving only clean and healthy. Cut off patients with a clean, sharp knife, sprinkle with crushed coal.
For 48 hours wrap up the rootsand then land in clean ground. Another possible reason - corny not enough light.
Long does not bloom
Dendrobium nobile can bloom in the third year after planting, when has increased enough leaf mass:
- Check if conditions are optimal.
- Wait until the end of the rest period or adaptation to new conditions.
Well heals the plant and promotes flowering biostimulator succinic acid. The drug is used strictly according to the instructions, spray the plant once a month.
Falling flowers and buds
Here, at the cost of great efforts, the flower has grown flower buds, from day to day they will bloom. There is a natural desire to boast, admire the beauty and the hostess proudly carries the pot to the most prominent place ... And the orchid experiencing wild stress. And soon all the buds are sadly lying on the floor ...
Do not rearrange a blooming orchid or in buds, for it is an ordeal. Worse only transplant:
- Still life of a blooming orchid and a vase with fruit can end badly! Fruits emit ethylene gas during storage, harmful to orchids,
- Draft, frost transport unfavorable for delicate buds.
The natural view of the Dendrobium Nobile, or the Dendrobium Nobile noble, served as the basis for a huge variety of hybrids.
It is not possible to buy a natural look in the store, but this is for the better, since the hybrids are adapted to grow in the conditions of human habitation.
Multicolored hybrid plants are often sold at the same price called mix.
The efforts of geneticists, botanists bred hybrids Dendrobium nobile mini small size.
A snow-white corolla with a yellow center.
Bright colorful colors with purple petals with a contrasting yellow lip.

Conclusion and useful tips
Dendrobium nobile is deservedly popular lovers of exotic flowers, thanks to an attractive appearance and relatively simple care.
Taking a little time to study the necessary living conditions of exotic, you can become real pro for this wonderful kind of orchids.
ORCHID DENDROBIUM LEAVING IN HOME TERMS
Flowering usually lasts for two to three months. Flowering will last longer if the plant is in a cool, dry place away from the batteries and direct sunlight.
Bright light is needed all year round, but I do not recommend direct sunlight, so it is better to slightly fence off the plant with a translucent film or a curtain.
How to transplant dendrobium?
The plant is transplanted into a slightly larger pot, transparent and equipped with appropriate holes that allow water to pass through. Replant carefully, so as not to damage the roots and pseudobulb. With each replanting the plant is filled with a new substrate, even if the former has not decomposed. The bark is quickly destroyed, replacement is necessary. A standard orchid substrate is used.
Substrate: special soil for planting
Before you start transplanting Dendrobium Nobile into another pot, you need to purchase a “light” soil mix, that is, one that conducts air and water well. Perfect as the basis of such a mixture, pine bark. You can add pieces of moss to it, and, if available, coconut fiber. Remember that orchid does not tolerate acidic soils. To prevent such a disaster, add some coal to the mix.
For a plant such as an orchid, the composition of the soil is associated with light. If you place your Dendrobium Nobile on the window sill of the south window, then the ground (and, therefore, the roots of the orchid) will need to be protected from drying out. Therefore, moss in the soil mixture put more.
If the orchid has to move to the north window, it will be necessary to take preventive measures so that moisture does not stagnate in the ground. You can crumble a little foam and mix it with soil mixture.
Lighting and temperature
Lighting is an important factor in itself, even outside its influence on the soil. If the window where the orchid stands is facing south, or south-west, or south-east, then on sunny days the orchid will need to be protected from direct rays. This can be done with the help of matte paper, which you cover the window with, thin muslin, gauze.
The plant will also need fresh air, so the house will have to be ventilated. But at the same time the pot with a flower should not be in a draft.
Special attention to the Dendrobium Nobile should be shown when the plant is preparing to bloom. At this time, if you are going to rearrange the pot, you need to make sure that the angle of illumination does not change. Otherwise, a naughty orchid can simply fold buds.
The orchid should be lit at least 10 hours a day. In winter, when the days are short and cloudy, you can turn on a daylight lamp for your flower when the evening comes.
The temperature in the room is desirable to maintain at least 20 ° C in the summer and 16 ° C in the winter.
But the orchid simply loves the moist air. In the cold season, when, due to the central heating radiators, the air in the rooms is dry, you can keep a spray bottle at the ready, and from time to time arrange a shower for the flower. To avoid dryness will also help wet towel, hung on the battery.
Watering and dressing Dendrobium nobile
Watering is what the plant needs regularly, throughout the year, so let's start with it. Recommendations depend on the air temperature in the apartment. The hotter and drier it is, the more often it will be necessary to water the flower. To use for this, it is preferable to not the water that you just collected from the tap. Minimum - the water must be allowed to settle. It is even preferable to pass it through the filter or boil it. In winter, if you live in an ecologically clean area, you can use the water obtained after melting snow, and warmed to room temperature.
Unusual advice from experienced flower growers: orchids like to take a rather hot shower from time to time. The water temperature can reach 45 C. With such care orchids will bloom particularly generously. Just do not forget to blot the leaves with a clean cloth so that they do not stagnate moisture.
In winter, during the dormant period, watering is reduced, and the soil is slightly loosened, they do everything so that the roots do not start to rot.
Now about fertilizers. Since your flower lives in a fairly cramped pot, and the ground day after day remains the same - the plant needs to be fed. Now in specialized stores sold a lot of fertilizer, designed specifically for orchids.
To feed the Dendrobium Nobile start from spring, when the orchid is just about to bloom. Fertilizers can be applied on the system: through two irrigations, on the third.
During the preparation for flowering, it is best to use fertilizers that contain phosphorus, not nitrogen.
You can multiply your orchid in several ways:
- separating from the plant "kids"
- dividing the bush itself into several parts
- preparing for planting cuttings.
“Kids” are separated from the “mother” when their roots reach several centimeters. As a rule, they safely take root in a new place, and after 2 years they begin to bloom.
If the orchid is already “adult” and has grown considerably, then once in 4 years or even less, it can be divided into parts. In this case, all the "received" plants will soon bloom.
Cuttings from the Dendrobium Nobile are obtained from those flower stalks that have already stopped flowering. The cuttings should be about 9-10 cm long. They are planted after sprinkling the slices with chopped chalk in pots filled with wet moss. Actually, they don’t even plant them in the usual sense, but put them on moss, and cover the pots with film on top.
Warm and humid. If such an atmosphere remains under the film, then after 3 weeks the cuttings will take root. And in a couple of months, young orchids can be transplanted into the ground that is most suitable for adults Dendrobium Nobile.
It is best to use special pots for orchids to breed capricious beauties. Flower shops always have their choice.
Transplanting orchids, try not to damage the roots. If any root is still broken, then, in order to avoid rotting, sprinkle the damaged area with coal or chalk.
At the bottom of the pot, under the ground, there should be a small layer of drainage. When planting, they try not to deepen the orchid too much so that the pseudobulbs do not disappear under the ground. If the flower is tall enough, they will provide support in advance.
The transplanted plant for some time is not kept in bright light.
The reasons for this may be many:
- excessive amount of applied nitrogen fertilizer
- shaded room
- excessive moisture, due to which roots begin to rot,
- low air temperature.
A “sissy” orchid will not wish to bloom even if it is in the room of a heavy smoker.
The origin and appearance of the orchid Dendrobium nobile
The perennial herb Dendrobium nobile belongs to the orchid family. Its second name, the Noble Orchid, characterizes this wonderful flower more accurately.
The adorable orchid Dendrobium Nobile is a worthy representative of the orchid family.
Like most representatives of the family of orchids, Dendrobium nobile came to us from Asia. India, Bhutan, Assam, Himalayas, Thailand, China - not a complete list of countries where this plant is found.
The translation of the name of this genus of orchids - "living in the trees" - speaks for itself. These orchids lead an epiphytic lifestyle - they grow on other plants or are permanently attached to them. Dendrobium nobile grows in deciduous and evergreen tropical forests. But there are also lithophytes that adorn harsh, moss-covered rocks.
Dendrobium nobile - epiphytic plant
In Dendrobium nobile, the sympodial growth type: from erect pseudobulbs, divided into segments, a thick juicy stem up to 90 cm is formed. Initially green, pseudobulba at the end of life (after about 4 years) turns yellow and dies. But before that, babies form at its top, giving birth to new plants.
Appearing in Europe in the XIX century, the plant instantly became incredibly popular. On its basis, new hybrids immediately began to be displayed, which in our time are no longer to be considered. For this reason, the real orchid Dendrobium Nobile in the store will not be able to meet.
Large, up to 9 cm in diameter, the flowers have a wax texture. The color is varied - white, yellow, orange, rich purple. A distinctive feature of the hybrids Dendrobium nobile is a special arrangement of peduncles. They are formed not at the top of the pseudobulb, but along its entire length. Inflorescences consist of 1 - 3 flowers. And the whole pseudobulb can be decorated at the same time with 70 flowers.
Orchid flowers Dendrobium nobile have a variety of colors
Content at home
Care and reproduction of Dendrobium Nobile at home are not difficult. But this, of course, when compared with the complexity of the maintenance of other species of the orchid family. Indeed, over Dendrobium nobile it is not necessary to shake and, as they say, blow dust particles from it. But you need to clearly understand that the orchid is not a simple-minded geranium, but an exotus that requires special attention and strict observance of the rules of care. The florist, who took the Dendrobium Nobile to his home, is obliged to create for an orchid a setting as close as possible to the natural conditions of its habitat.
When compared to other orchids, the Dendrobium nobile is not so whimsical
The advantages and disadvantages of an exotic flower
Among the advantages of this orchid, flower growers note the beauty, the variety of shapes and colors, the pleasant aroma, the long flowering. And, of course, the character is not capricious compared to other orchids.
Among the shortcomings called intolerance to dry air, complicating the care of the Dendrobium Nobile in the home environment of apartments with central heating.
One of the undeniable merits of the Dendrobium nobile is colorful flowering.
Planting and transplanting
Representatives of the orchid family do not really like transplanting, and Dendrobium Nobile is no exception. The plant is transplanted 1 time in 3 years - and then on the imperative need:
- if the plant is sick,
- in case of compaction or salinization of the substrate,
- the plant has grown strong, the pot has become cramped.
Dendrobium nobile are transplanted in spring, after flowering.
Planting or transplanting a Dendrobium Nobile requires a soil mix that conducts air and water well. The basis of this mixture is the pine bark of the middle fraction. In it, if desired, you can add chopped moss, coconut fiber. Be sure to include in the composition of the substrate pieces of coal, they will prevent acidification of the soil.
You should also consider the factor of illumination.
- if the plant is located on the southern window, then more moss can be added to the mixture - it retains moisture longer,
- on the north window, on the contrary, the mixture should “breathe” more - it is better to add small pieces of foam as a baking powder to the pine bark.
Which pot to move the plant
Dendrobium nobile rather big plant, especially adult specimens. Therefore, it is better to choose a clay tank that passes through air with good drainage holes.
Before planting, clay containers should be prepared: calcined in the oven, let cool and soak in clean, settled water for 2 hours.
Now there are a lot of special ceramic orchid pots on sale that have holes in the walls, which significantly improves gas exchange in the root system. The size of the pot should correspond to the size of the root system and only 2 cm greater than the diameter of the previous one.
Recently, there have been many decorative pots adapted for growing orchids.
How to transplant: a step by step description of the process
- From the root system of the plant completely remove the old soil. If this is difficult to do, the plant pot is soaked in water, and then the swollen substrate is very easily removed.
The orchid is carefully removed from the pot, pre-soaking the roots and the substrate with water
Orchid roots before transplant carefully inspect and remove rotten areas
The orchid is set in the center of the pot, the substrate is filled to the sides
Dendrobium nobile sometimes needs support
Plants recover after transplanting without heat and bright light
Dendrobium nobile is grown not only in pots. Orchids placed on a block grow very well. A block is a material to which a plant can be attached. To do this, you can use the bark of pine or cork oak, a block of tree fern. Recently, this method of landing is becoming increasingly popular.
Orchid Dendrobium Nobile on the block
The orchid will live and bloom with proper watering.
First, let's talk about the quality of the liquid. Water should be soft, filtered. You can use boiled and cooled. Its temperature should be several degrees above room temperature.
Each apartment has its own microclimate, so under different conditions of maintenance it is impossible to establish clear rules for watering: the gardener must be guided by the level of illumination and the temperature of his own home. The hotter, the more generous should be irrigation, and, conversely, as the temperature decreases, the intensity of moisture decreases.
Spring and summer watering is abundant, but not frequency. Filling the bark pot should dry out completely before the next moistening. In the winter, watered very carefully to avoid rotting roots.
The ideal method of moistening still remains the method of immersion, when the pot with the plant is immersed by 1/3 in a container with water, so that the roots and the substrate are thoroughly saturated, then allowed to drain off excess moisture.
Many growers recommend regularly bathing an orchid under a hot shower, the temperature of which is from 40 to 45 ° C. This procedure not only cleans the leaves, helping to improve gas exchange in the tissues, but also stimulates flowering. Be sure to blot the water in the leaf axils after a shower to avoid rotting.
Лучше всего Дендробиум нобиле поливать, применяя метод погружения
Сколько надо удобрять
Так как орхидея растёт в бедном грунте, удобрять её нужно обязательно, но только в определённое время. Подкормка начинается весной, когда возобновляется активный рост цветка, и продолжается в период цветения. You should never forget how much and what kind of Dendrobium nobile feeding is needed. It should be used only fertilizers intended for orchids. Their rate is reduced by half from that indicated in the instructions. Top dressings are brought at each 3rd watering. Not overkill will be foliar application and highly diluted fertilizer. By alternating these methods, you will help the plant absorb nutrients as much as possible.
Dendrobium nobile has one peculiarity. In the spring not only growth buds, but also flower ones wake up. A passion for nitrogen fertilizers will lead to the formation of a large number of children, but you can not wait for flowering. Therefore, when sprouts reach almost half of their size, discard nitrogen-containing supplements in favor of those that contain phosphorus.
Preparing to bloom
Blooms Dendrobium Nobile at different times of the year, this is due to the incredible number of hybrid forms. The flowering period takes a month, sometimes a little more. Its duration depends on the air temperature of the room in which the plant is contained. The higher it is, the faster the orchids will bloom. The ideal temperature during flowering is 18 C.
Sometimes the orchid refuses to bloom. Why? This happens if you do not pay attention to the requirements of the plant to the conditions of detention. If you observe the right combination of lighting, temperature and watering parameters, there will be no problems with the development of flower buds.
- Since spring, the lighting should be as bright as possible.
- The temperature during the day is within 25 C and not higher, at night it is 3–5 C lower, otherwise flower buds will be reborn as a growth bud.
- Watering plentiful, with good drying of the substrate.
- Do not overdo it with fertilizers. Increased concentration can harm the roots.
After flowering, all peduncles are removed. If you need a transplant, do it. A few days after transplantation, do not water the orchid to prevent possible development of rot on the roots.
And most importantly - after flowering for the orchid must necessarily come a period of rest.
Old yellowed pseudobulbs do not rush to remove. They will serve as food for young growing shoots. You can cut them only after they dry. Do not forget to sprinkle with a cut coal.
For Dendrobium Nobile to actively blossom, he needs a lot of light.
How to care when the dormant period
Dendrobium Nobile - cyclical plant. It is necessary to create an orchid with such conditions that it goes through all the cycles of its development, provided by nature. The rest period is very important for the flower. It is at this time that he accumulates strength, begins preparations for the next flowering.
In our climatic conditions, Dendrobium Nobile leaves for winter rest by necessity. This is due to a decrease in light intensity.
- The plant must be taken out to a room with a daytime temperature of 15 - 16 ° C, at night - 10 - 12 C.
- Watering stops. If pseudobulbs began to frown, you can lightly spray the substrate and leaflets.
- There is no need to specially maintain the humidity around the plant during this period.
- After 2-3 weeks, flower buds should appear at the interstitial sites of the pseudobulb.
After flowering orchid should rest
This method of reproduction is subjected to an adult and healthy Orchid Dendrobium Nobile, having at least 3 pseudobulbs. Since the procedure for the plant is stressful, it is carried out no more than 1 time in 4 years, combining with a transplant. Divide only after the Dendrobium nobile has blossomed.
- Before dividing the bush, the orchid's root system needs to be well nourished with water so that the roots become more flexible and pliable.
- Remove the plant from the pot, shake off the substrate. Split the knife divided into parts so that each had 2 - 3 pseudobulbs with roots.
- Sections immediately fall asleep crushed coal.
- Delenki leave for a day in a slightly shaded place for drying wounds.
- We plant in a suitable soil mixture and take care of it as after transplantation.
- New plants will bloom next year.

Why choose cutting
This method is considered the easiest.
- For grafting, you need to cut off the old pseudobulb without leaves (plant stem) and cut it into pieces. Each must have at least 1 sleeping kidney.
- Cut locations are treated with coal dust.
- We put the cuttings in a container filled with wet moss. Cover with a bag or glass to create greenhouse conditions inside.
- We keep the greenhouse on a bright diffused light, regularly moisten and air it.
- The root system is formed after 2 - 3 weeks, and the children themselves grow very quickly.

When the roots grow by 5 cm, transplant the plants into separate pots with small pine bark in half with coconut fiber and look like adult orchids.

“Flowers are the remnants of heaven on earth” - John of Kronstadt.
All bloom equally easily, just for the winter you need to arrange a period of rest.
Mine from spring to autumn live on the street, and in winter - on a cool veranda. On the one that winters in a warmer room (+ 18–19 degrees) mostly children are formed and not very many flowers. And again: in a warm room, they quickly fade. Therefore, I try to keep them cool all the time.
The noble dendrobium became one of my first orchids, when it was rarely possible to find them in stores in stores. Fortunately, those numerous hybrids that can be purchased are quite accommodating and unpretentious in their care. Unlike the natural species, which needs a decrease in temperature in the autumn-winter period, it is enough for them to ensure a good temperature difference. If it is possible that some plants delight flowering 2 times a year. In summer, the plant feels best outdoors. I usually still take them out in the spring to the open balcony after the plant has faded and has begun to grow actively. During the summer, the dendrobium expels new bulbs, and often in August, when the difference between day and night temperatures is maximum, it blooms the second time.
With good care, plants can reach impressive size, but I do not advise without special need to divide the bush, because the more the bush, the more luxurious the flowering will be.
But the main thing with which this kind of orchids bribes me is an amazing aroma, slightly sweetish, very pleasant and absolutely not cloying.
The variety Dendrobium nobile is not as popular as phalaenopsis. In our flower shops you can meet Dendrobium, except on New Year's Eve. But more and more fans of this beautiful orchid.

And this means that after a short time, you will be able to create not only a whole orchid garden, but also you will give a beautiful plant to your friends.
The dendrobium is a noble houseplant that happens to be a living decoration, as it is more durable than many cut flowers. Dendrobium Nobile hybrids are terrific potted plants. In their upright position, they look exactly like a vibrant bouquet, the flowers are so closely pressed together that it becomes difficult to see the stems under the flowers.
Dendrobium nobile is a pleasant exotic decoration not only for residential premises, but for offices, as it is easy to care for and flowering lasts for a long period. Used as cut flowers, can stand in a vase from 15 to 60 days.

DENDROBIUM NOBILE CARE AFTER FLOWERING
What to do with dendrobium nobile after flowering? Need pruning after flowering or not? Such questions can be found in many forums dedicated to orchids. I will try to answer these questions concisely and correctly.
- The dendrobium noble (nobile) does not need pruning after flowering, like an orchid phalaenopsis. This is so because the dendrobium has pseudobulbs connected with each other. Each individual pseudobulb blooms only once. On the already faded pseudobulbe, flower buds can bloom, not blooming in the first bloom.
- You should know that the entire length of the pseudobulb are buds capable of blooming. Therefore, if the buds appeared on the one hand, you should wait until all the buds present in the pseudobulba have faded. Novice flower growers often cut off a faded pseudobulb, which leads to irreversible disease processes and the death of an orchid.
- To cut off the pseudobulb, in which all the buds have faded, it is impossible, since the old pseudobulb is the organ that feeds the young shoots during the growing season. You can cut off a pseudobulb only when it begins to dry out and the leaves fall off. Bulba gently peel off at the base, the cut is treated with activated charcoal (cinnamon).
- 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.
What does it look like?
As for the external features, the Orchid Dendrobium Nobile is referred to the sympodial type on the basis of growth. That is, in the spring of old shoots a root fan is formed and swell from 2 to 4 buds. By autumn, these young shoots grow to the maximum and are already fully mature. The plant sometimes reaches 60 centimeters, the minimum height of this individual is about 30 centimeters.
The length of the flower leaves reaches 10 centimeters, they are elongated in shape, systematically falling down. Large pseudobulbs of Dendrobium nobile, which are almost the same size as the main stem, produce flower stalks in the second year of cultivation.
- The main peduncles appear at the very top of the bulbs without leaves.
- If the plant is taken care of correctly, then the whole trunk will be covered with these flower stalks.
- Such flowering nobile amazes the imagination with its beauty - after all, it is completely “stuck round” with inflorescences of three or more flowers that grow in groups in one hitch.
- The diameter of a single flowering varies from 4 to 7 centimeters, and their colors on one stem can be of different tonality of the same color or in contrasting shades, as in the photo.
The most common specimen is with oval-shaped petals and slightly wider sepals, pink and white in one individual. The darkest shade is always on the core of a rounded lip, and the lightest - on its edge.
The pots should be opaque, small in size, but they will not bring too little good either. It is better to choose dishes of medium size, taking into account the growth of your pet. When buying, you should immediately find out from the seller what size a particular individual will reach in two or three years. Based on these parameters you will be much easier to make a choice. And if in doubt, ask for help from a consultant. So you will save both your time and the health of your future pet.
