Dendrobium nobile orchid
The genus of orchids Dendrobium includes a huge variety of subgroups that differ from each other in appearance, size and arrangement of flowers, growth characteristics and rules of care. An important place among them is occupied by such a subspecies as Dendrobium nobile. Its name literally translates as "Noble Orchid", which is quite consistent with its appearance and sophisticated aroma.
The homeland of the Noble Orchid is the south of Eurasia, its temperate climatic zone - first of all, the territory of North India, Indonesia, and South China. She is often found in the Himalayas. In Europe, this species, imported from India, appeared rather late - in 1836.
Dendrobium Nobile is especially popular with novice growers. Caring for her is easier than for some other types of orchids, while her beauty is in no way inferior to most of her "relatives". However, like the overwhelming majority of ornamental plants, orchids are considered rather capricious flowers, and those who decide to have this tropical beauty at home need to remember a few simple tips.
Dendrobium nobile orchid - care features
Location and lighting
It is very important to choose the right place for the orchid. Dendrobium nobile is a light-loving plant that does not tolerate darkened rooms and gloomy halls. For the normal course of photosynthesis, the orchid needs a sufficiently large amount of light, if it is not enough, then the plant most likely will never be able to bloom. However, be careful: direct sunlight can cause burns on its leaves, causing enormous harm to it.
The southern and southeastern windowsills are best suited for this type of orchid. It is also very useful in the summer to take the orchid out of the room to an open place, to the garden or to the balcony.
Under natural conditions, the noble orchid grows in the subtropical climatic zone, so it feels very comfortable at room temperature. The ideal mode for Dendrobium Nobile is 20-25 ° С. In winter, in the absence of an additional heater, the temperature may drop to 16-18 ° C. However, keep in mind that the temperature during the day should not fluctuate more than 4-5 degrees.
The more pronounced changes in her are perceived by the heat-loving beauty as stress and can seriously harm her. If, nevertheless, there is a need to change the temperature regime, then a few days before that you need to start preparing the orchid for changes - first of all, do not feed and reduce the abundance of watering. A noble orchid may not survive a low temperature at all.
Since Dendrobium nobile is a tropical plant, the conditions for its watering should be as close as possible to the conditions of its natural habitat.
First of all, a novice florist should remember that the orchid of this subspecies does not tolerate excessive soil moisture. It can be watered again only after the substrate in which it grows completely dries out. Thus, the frequency of watering directly depends on the air temperature - the higher it is, the more frequent watering will be required. In winter, it is better to switch to dry content altogether - that is, to reduce watering to a minimum.
Warm up the water before watering the orchid. The liquid should be warm enough to resemble the tropical rainwater of Indonesia and China as much as possible. Very useful for this plant "shower" watering, wetting not only its roots, but also the leaves.
If the nobile orchid grows in a pot, you will definitely need a pallet. However, make sure that the water does not stagnate in it - this can lead to decay of the roots. If you placed the plant on blocks, then you will have to water it daily, best of all in the morning. Only with this kind of care can you ensure healthy growth and long-lasting flowering of your orchid.
Top dressing and fertilizers
Top dressing is a prerequisite for keeping the nobile orchid. It must be carried out regularly - this is necessary in order to maintain the health of the plant's root system. However, be careful: fertilizer, like water, should be in moderation.
Before you start feeding, be sure to find out which fertilizer is best for your strain. Since there are a lot of types of orchids, and the differences between them are sometimes more than huge, an incorrectly chosen top dressing can harm the plant, and not benefit. You should also not use standard plant food for indoor plants - it is not intended for the substrate in which the orchid grows.
Many novice growers are sure that there is never too much fertilizer. This is not true. It is impossible to get carried away with feeding, since it can cause serious damage to the roots. It can be used only during the flowering period, no more than several times a month.
The noble orchid is a gentle plant and does not like frequent changes. Therefore, it is better to transplant it as little as possible. The need for a transplant appears only if she has "outgrown" her pot, and it has become cramped for her. You will notice when this happens - the roots of the flower will hang down without going deep into the soil, and its growth will slow down greatly.
Orchid is a rather capricious flower, but its beauty and long lifespan more than compensate for all the difficulties that a plant breeder may experience when caring for it. Subject to the conditions of its maintenance, Dendrobium nobile will delight you with its bright flowering for many years.
A herbaceous perennial plant, the Dendrobium Orchid (Dendrobium) is a member of the Orchid family. From the Greek "dendrobium" is translated as "living on a tree", this is due to the fact that this plant is an epiphyte, but among the species of this genus there are also lithophytes that live on stones. This genus unites more than 1200 species that can be found in natural conditions in the Philippines, Australia, New Zealand, Japan, China, Oceania and New Guinea. All these species can differ greatly from each other both in the shape and color of foliage and flowers, and in the manner of placing flowers on the stem, flowering time and much more.
Description of the plant
These orchids naturally grow high in the mountains in India, Nepal, Thailand and other countries of Southeast Asia. This plant first appeared in Europe in 1836. Dendrobium Nobile grows up to 60 cm in height. This plant has erect, fleshy stems with a characteristic glossy sheen. Leaves grow on them only in the upper part. Peduncles on this plant appear only in the second year of life. During the flowering period, its trunk is densely covered with pink, red, white or purple flowers.
Flowers in this type of orchid form inflorescences. Depending on the age of the flower, there are up to 3 buds in it. And up to 70 flowers bloom completely on the peduncle. In diameter, the size of one reaches 5-10 cm. Natural varieties of Dendrobium have snow-white petals with purple edges. The lip is cream colored with pink edging and the throat is purple. The petals are ovoid and have elongated sepals. The flowering period is in late winter and early spring. In this case, the life of each flower is 2 months.
This orchid species is sympodial. He has new rosettes formed on the rhizome at the base of the old ones. The life span of such sprouts is 2-4 years. The stems of a young plant are directed upwards. Over the years, they tilt and become shallow. Over time, the length of the peduncles reaches 1 m. They become bare and die off after the formation of daughter rosettes. Flower buds and new shoots form in the leaf axils. They can be used for breeding.
Possible Content Issues
Orchid needs in constant ventilation of the room, without drafts.
Dendrobium flowers reach 9 cm in diameter, they literally cover the whole plant... Most often they are delicate white, with a yellowish center, very aromatic. There are other colors: yellow, red, pink. You can create a small bright variegated flower bed of dendrobiums on the windowsill, which will smell fragrant from early spring to summer.
How to care for a dendrobium nobel orchid?
Epiphytic orchids need fairly poor and loose soil. The substrate is prepared from crushed pine bark, sphagnum moss and peat... Add to the mixture charcoal... It is important that in the ground there was no calciumbecause most orchids do not tolerate it well.
You can use ready-made soil for epiphytic orchids.
Will fit and chopped bark of conifers... In this case, larger pieces are placed on the bottom, small ones on top. When adding a small amount peat the mechanical properties of the substrate are improved, and the acidity that is optimal for orchids is achieved.
For planting, use ordinary pots and hanging baskets made of rails. The main thing is to provide good drainage, it should be at least ¼ of the height of the pot. To do this, a thick layer of broken brick or crushed granite is laid on the bottom of the container. Expanded clay and limestone are not suitablecontaining calcium.
A thick layer is pre-laid in the baskets sphagnum.
An orchid attached to a snag looks beautiful. In this case, it can be placed in a special greenhouse along with bromeliads.
In nature, dendrobium nobile grows at very bright but diffused lighting... In the room, especially in winter, light is sorely lacking, therefore, from May to September, orchids are best kept on the east and west windows, and in winter - on the south ones.
From time to time, the pot is turned, and on cold days it is removed from the windowsill.
Types and varieties with white and pale pink flowers less demanding, if I may say so, to lighting and, when supplemented, grow well even on northeastern windows.
Plants with bright red, pink, yellow flowers should be placed on the south-east, south-west, and in winter and on the south windows, and at the same time use additional illumination.
- If a too much light, then the orchid continues to grow and grow pseudobulbs, but at the same time they will be smaller, which will further affect flowering.
- When insufficient lighting pseudobulbs will grow thin and long, and flowering in this case, as a rule, does not happen.
The orchid quickly absorbs water only with sufficient light, therefore, when it decreases, watering is also reduced.
Water the orchids after the top layer of moss or substrate will dry out... In the summer, 2-3 waterings 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, it is best to use boiled, with a temperature several degrees higher than the air temperature.
From April to September, orchid fertilizers containing nitrogen, potassium and phosphorus in equal amounts. This should be done after two waterings on the third.
Temperature affects the plant only when it receives enough light. With a lack of it, orchids will remain dormant, even when the temperature rises.
If the temperature is too high, the evaporation of water through the stomata on the leaves increases, and the roots do not have time to provide the plants with the required amount of moisture.
Therefore, in the heat, it is necessary to increase the humidity in the room. To do this, the pots are placed on trays filled with water and pebbles or damp moss. The leaves are sprayed regularly.
To prevent the development of fungal diseases, the room is often ventilatedwhile avoiding cold drafts.
On warm sunny days, orchids do well outdoors.
Optimal conditions of detention
In second place - air humidity... Dry air is destructive for gentle tropical exotic. During the heating period, you need a humidifier or a tray with wet pebbles, in no case touching the roots.
A viable plant can survive in temperatures ranging from 3̊ to 42̊ C.
Dendrobium will become a decoration and pride of the house only in optimal conditions for it. Life Cycle Period:
- To build up green mass:
- Day - 24̊С-27̊С
- Night - Not higher than 22̊C-24̊C.
- To stimulate flowering:
- Day - 24̊C-25̊C
- Night - 24̊-25̊, optimally 18̊-20̊.
The difference in day and night temperatures is a must for those who want have a healthy plant in colors. Do not go beyond the optimal temperature range of 16̊C-30̊C.
Transplant and care after purchase in the store
Having bought a blooming orchid, do not rush to transplant it... Transplantation is possible only after the end of flowering and with sufficient grounds, otherwise it will only harm the plant.
Watering and feeding
In the warm season, during the period of active growth of the plant, need more frequent wateringthan in winter and autumn.
Should be given dry the soil completely between waterings, and for each specific room, the frequency of watering should be selected empirically.
The orchid should be well watered, otherwise it will die.
On average, from mid-spring to early 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 the water from the pan, the roots can suffer from rot.
If the plant is green and fresh, the roots are clean and without rot, then watering is optimally matched.
We use special fertilizer for orchids... The main feature of such solutions is that they do not settle on the ground, do not accumulate and do not harm the roots.
|Fertilizer type:||Phase of the year:||Period:|
|Nitric.||Growth of green mass.||With the beginning of active growth, approximately March. Fertilizer is added to water for irrigation, every other time.|
|Potassium phosphorus.||Formation of buds.||When the buds appear.|
How to stimulate flowering?
Dendrobium Nobile lives in accordance with the annual development cycle, so the stimulation will be effective in the spring, directly after a phase of active growth:
- Illumination with phytolamp on cloudy days and additional illumination of additional 4-5 hours every day
- Spraying with succinic acid according to the instructions
- Apply cytokinin paste to visible kidneys in the sinuses.
Cut directly dried inflorescences.
Prevention of diseases and pests
- Quarantine... The new plant should be kept separately for a month. This is enough time for hidden problems to appear - pests or diseases.
- Pests can move on the windowsill from the street with an open window
- Draft... It is necessary to place the pot away from the open window and to protect the roots and leaves from hypothermia in the wind, there is a danger of decay
- Cold windowsill... In nature, cold is unfamiliar to orchids, the roots must be isolated with a stand for winter
- Sufficient time between waterings... 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 blooming and the leaves may crack. From a "hungry" flower, you will not wait for a lush bloom.
A friend bought Dendrobium Nobile five years ago. Then she gave me a couple of bulbs for planting, said to plant in the moss. Now I can say that of all orchids, these have become the most beloved. Very easy care, cool conditions are suitable, rarely gets sick (well, at least for me).I have already bought several hybrids myself, all bloom once a year, magnificently and beautifully.
Nina, Saint Petersburg
I had been eyeing orchids for a long time, but it was scary - whether I could grow such beauty myself. I bought two flowers for the occasion, as it turned out - Phalaenopsis and Dendrobium. The first one did not please me a lot, perhaps my inexperience when leaving was affected. But I have even planted Dendrobium in three pots, picked up the pots for them. Bloomed beautifully - lilac with white and yellowish color. All the shoots are covered with flowers, I have never seen this. I urgently bought literature, found all the information. I want to breed more of these beauties!
Dendrobium Nobile is a luxurious representative of the Orchid family, attracting flower growers with simple care and bright abundant flowering. Providing the plant with the necessary conditions, even a novice amateur will be able to grow an exotic plant at home.
