Such a genus as Coelogyne is directly related to a fairly large family of orchids. This genus includes more than 120 plant species. Such plants growing in natural conditions can be found in vast areas of the tropical forests of South and Southeast Asia, as well as on the islands of such oceans as the Pacific and Indian. Most of these plants are epiphytes, but lithophytes and terrestrial ones are also found.
Caring for a Coelogyne orchid at home
All year round, such a plant needs bright lighting. So, its level should be equal to at least 4000-6000 lux. The best place to place it is an east or west window. At the same time, there will be little light on the window on the north side of the flower, and on the south – it will need shading from the direct rays of the sun, which it does not tolerate.
At the same time, do not forget that daylight hours should be at least 12-14 hours throughout the year. In this regard, in the winter, he needs additional lighting.
The temperature regime completely depends on the type of orchid. In the warm season, almost all species need moderate temperatures from 20 to 25 degrees. In winter, the heat-loving Coelogyne beautiful should be protected from low temperatures, so the room should not be colder than 10 degrees, while the cold-loving comb Coelogyne needs to be cool at this time (about 5 degrees).
It should be remembered that some species have a dormant period, while others do not. So, for example, the beautiful Coelogyne does not have a dormant period, and therefore flowering can begin in any month, regardless of the time of year. The fringed Coelogyne also does not have a dormant period, but this species blooms at a strictly defined time. A pronounced dormant period is present in comb Coelogyne, it begins at the end of the spring period and has a duration of 2–3 weeks. At this time, the growth of the root system is suspended, and the pseudobulbs become very wrinkled.
How to water
Watering is recommended by immersing the pot in a basin filled with water. Take out the pot after a few minutes. For irrigation, you need to use only soft water, which should be filtered or boiled. The fact is that such a plant reacts very poorly to the salinization of the substrate (a whitish coating forms on the surface).
During the dormant period, this orchid needs to be watered much less and only after the substrate has completely dried.
Requires high humidity. In order to raise it, expanded clay is poured into the pan and a small amount of water is poured. Also, the foliage must be moistened from the sprayer at least a couple of times a day (best in the morning and evening hours).
For planting, a purchased ready-made soil mixture for orchids is quite suitable. It must be necessarily fine-grained and contain a small amount of decomposed leaf compost and small (up to 1 centimeter) pieces of pine bark. It should be noted that the amount of bark from the total volume of the substrate should be about half.
Those species that have long roots (for example, fringed cologina) are recommended to be grown on blocks of pine bark. The roots are fixed on the surface of the block with a wire and covered with a layer of sphagnum. With this method of growing, you need to water more often, as well as spray.
Transplantation is carried out in case of emergency. So, this is when the pot or block becomes too tight, while young growths go far beyond the capacity.
If the bush is large enough, then when replanting it, it should be remembered that it is necessary to put a weighting agent on the bottom (several large pieces of granite or pebbles). Thus, you will secure the flower from tipping over.
Top dressing is carried out during intensive growth 1 time per week. And the plant also needs additional foliar top dressing. To do this, use ready-made fertilizer, specially designed for orchids. When the plant blooms, the number of dressings is reduced to the 1st in 4 weeks.
Propagation of this kind of orchid is the easiest by division. An adult specimen with several mature pseudobulbs is suitable for this. It should be remembered that on each division there should be several pieces of young and old pseudobulbs with a developed root system.
Pests and diseases
Most often, a spider mite settles on a plant. If pests are found, the flower should be given a warm shower, and its foliage should be washed with special care. An identical method of struggle is used when aphids or whiteflies are detected.
Most often, the plant suffers from a variety of fungal diseases. If you start treatment with fungicides at an early stage, you can cure cologin quite quickly.
Types of Coelogyne
All species have common features. So, they have a sympodial growth pattern and oval pseudobulbs with a smooth surface. From the upper part of each pseudobulb grows 1 or 2 leaves of a belt-like shape and green color. Quite long peduncles grow from the base of the pseudobulb, on which there are several pieces of fragrant flowers. Each flower has 5 narrow individual petals and 1 rather wide lip located below.
At home, several different types of such orchids are grown. The most popular among flower growers is:
In nature, it can only be found high in the Himalayas, while it grows almost at the very border of the snows. This plant is cold-loving and has spherical-elongated pseudobulbs, which reach a length of 3 to 5 centimeters and 2 long leaves. On peduncles are placed from 3 to 8 pieces of flowers of white color and fairly large size (diameter up to 10 centimeters). These flowers differ in the shape of the lips. So, it is three-bladed and has 5 well-defined “scallops” – outgrowths. Flowering occurs from winter to early spring.
Fringed cologina (Coelogyne fimbriata)
This orchid is native to India, Vietnam, South China and Thailand. Such a compact plant is thermophilic. In height, the pseudobulbs, bearing a pair of leaves, can reach from 2 to 3 centimeters. Peduncles bear 1-3 not very large flowers (up to 3 centimeters in diameter), painted yellowish-green. The lower lip of the flower has a brownish-burgundy pattern. Blooms from August to October.
They are native to islands such as Sumatra and Java. This species is univalent. On fairly short peduncles are 1-3 large greenish-yellow flowers. The three-lobed lip is painted pale brown, and reddish veins and white specks are clearly visible on its surface.
The above species are considered the most non-capricious and it is they who are advised to grow novice orchidists.
