Coelogyne fimbriata orchid plant care and culture

 Coelogyne fimbriata also called as The Fringed Coelogyne, Broughtonia linearis, Broughtonia linearis, Coelogyne arunachalensis, Coelogyne laotica, Coelogyne longiciliata, Coelogyne ovalis, Coelogyne padangensis, Coelogyne primulina, Coelogyne xerophyta, Pleione chinense, Pleione fimbriata, is a species of the genus Coelogyne. This species was described by John Lindley in 1825.

 Coelogyne fimbriata occurs in the Himalayas, Myanmar, Malaysia, Thailand, Laos, Cambodia, Vietnam and China. It grows epiphytic on trees or lithophyte on rocks in primary, broadleaf, evergreen lowland forests or primary montane forests at an altitude of 640 to 2300 meters above sea level.

 It is a medium sized, cool to hot growing epiphytic or lithophytic orchid with 3 to 4 cm between each, ovoid to ellipsoid, 2 to 4 cm in length and 1.5 cm in width pseudobulb that carry 2 apical, oblong-elliptic, acute, plicate, 5 nerved, gradually narrowing below into the petiolate base, 9 cm in length and 1.5 cm in width leaves.

 The Fringed Coelogyne blooms in the fall arising on the newest mature pseudobulb with a terminal, slender, 4 to 5 cm long, erect, fractiflex rachis, 1 to 3 flowered, racemose inflorescence subtended with a narrow basal sheath and carrying 1 to 3, fragrant, long-lived flowers held just above the leaves. The flowers are greenish with brown veins on the lip, about 3 cm in diameter. Tepals narrowed, lanceolate, with pointed tips, about 2 cm in length and 0.8 cm in width, on the reverse side have veins. Petals are somewhat narrower than sepals. The lip is threefold, 2-3 cm long, its lateral parts long, rounded in front and slightly covered with fringe, and the anterior part round and very much rugged with fringe, from the base of the lip there are three wavy longitudinal protuberances (outgrowth), the middle of which is the shortest and very quickly turns into a simple brown line. The column is arched.

COELOGYNE FIMBRIATA ORCHID PLANT CARE AND CULTURE

 Cultural information should only be used as a guide, and should be to be adapted to suit you. Your physical location; where you grow your plants, how much time you have to devote to their care, and many other factors, will need to be taken into account. Only then can you decide on the cultural methods that best suit you and your plants.

Light:

 Coelogyne fimbriata loves bright sunlight and is able to tolerate direct morning and evening sunshine (25000-35000 lux), however, in hot summer noon on windows of southern orientation and in the afternoon on western windows it should be protected from direct sunlight, or in the shadow of other plants, otherwise the orchid leaves can get sunburn, and the plant itself is severely stressed by regular overheating (yellowing and premature falling of the leaves). Bright sunlight is one of the main prerequisites for the flowering of orchids of this species, and if the lighting is insufficient (especially at a time when new shoots reach 1/2 of their usual size), then the orchid will simply not bloom, as new pseudobulbs grow underdeveloped, i.e. incapable of flowering. During the whole year, the duration of the light day should be at least 10 hours, ideally 16 hours. An ideal place for keeping a plant is a combination of windows, for example, in the autumn and winter - these are the southern and western windows, and in the spring and summer - the eastern and south-eastern. When growing a plant all year round in the conditions of the north or east window in the autumn-winter period, in addition to natural lighting, it is strongly recommended to use artificial light and in spring and summer - east and south-east.

Temperature:

 The cultivated plants should be kept under the following temperature regime which are better regularly flowering: Summer temperature of about 20 ° C in day and night at 12 ° C at night. Winter temperature for day and night not higher than 10 ° C. For the successful cultivation at home, it is necessary that the night temperature of the content is always at least 8-10 ° C lower than the daytime temperature.

Humidity:

 In their natural habitats, the relative humidity of the air rarely falls below 70%. In conditions of high humidity, it is necessary to regularly ventilate the room where the plants are kept, since wet, stale air is an ideal medium for the mass reproduction of various fungal and bacterial diseases.

Substrate, growing media and repotting:

 Coelogyne fimbriata can be grow in bare root system on blocks, or in low plastic or clay pots (in the manner of pots). The substrate must be both very breathable and moisture-consuming at the same time, so the mixture of the bark of coniferous trees with charcoal, roots of ferns, humus and sphagnum moss (up to 50%) is best in its quality. When growing orchids on blocks to prevent rapid drying of the root system of the plant, it is recommended to make a small interlayer of moss between it and the block. Above the roots, you can also put live or dry sphagnum.

 At the transplant, this species reacts negatively enough and may subsequently miss 2-3 flowering, i.e. to form pseudobulbs that do not give flowers, so transplanting an orchid is desirable only when it is really necessary, for example, in cases of severe salinization or condensation of the substrate, at its critically high or low pH (a rate of 5.5 to 6.5) when the plant grows very much and the pot will become too small for it (pseudobulbs will begin to hang from the edges of the pot). The best time for transplant is the spring period.

Watering:

 Watering this kind of orchids directly depends on the overall temperature of the content, the higher it is, the more often and abundant it is necessary to water. Plants growing on blocks, it is desirable to water daily in the morning, so that by evening their roots could dry out relatively well. When watering orchids in pots, it is necessary to remember that excess water during watering should flow freely out of the pot, as the stagnation of water both inside the pot and in its pallet can very quickly lead to rotting of the roots and the lower part of the plant. The substrate between the irrigations should dry relatively well, but do not dry out completely, i.e. is always in a slightly moistened, but not wet state.

Fertilizer:

 During the new growth period, this type of orchids is fertilized every 1-2 weeks in the usual fertilizer concentration indicated on the package. In addition to root top dressing, it is also recommended to produce a foliar dressing when the outer part of the plant is sprayed with a very diluted fertilizer. It is best to feed the orchid, alternating both these methods.

Rest period:

 In winter, Coelogyne fimbriata undergoes a rather strict and distinct period of rest. Since mid-November, these orchids are placed in a medium-lit area (north or east window) and contain a few drier and colder than usual, and do not fertilize. The ideal temperature of the content is a constant temperature of 10 ° C, i.e. the same day and night - without changes. Watering should be arranged in such a way that between the waterings the substrate does not just dry very well, but about 15-20 days it was completely dry, as a rule, in the amount of the whole winter it is necessary to water 2-3 times. With the advent of new shoots, the rest period ends: the total temperature of the content increases, and the watering of the orchid resumes in the usual volume. The refusal of the flowering can be caused by too hot content, a non-observance of the rest period, the absence of sufficient differences between day and night temperatures, insufficient lighting or the general stress state of the plant (for example, a bad root system).
