Coelogyne parishii, also called as Parrish's Coelogyne, Pleione parishii, is a species of the genus Coelogyne. This species was described by Joseph Dalton Hooker in 1862.
IDENTIFY COELOGYNE PARISHII - PARRISH'S COELOGYNE
Coelogyne parishii is native to Indo-China. It is found growing in the lowland forest of Cambodia, Laos, Myanmar, Thailand, Vietnam at elevations of around 120 meters above sea level.
It is a small medium sized, warm to hot growing epiphytic orchid which reaching 5-10 cm in height with very narrowly conical, yellowish, angled pseudobulbs. The leaves are 2, apical, elliptic or lanceolate, subacute.
Parrish's Coelogyne blooms in spring from the terminal, pendant or erect, 10 cm long, racemose, 3-5-flowered inflorescence. The brilliant yellow green flowers are large, simultaneously opening, fragrant.
COELOGYNE PARISHII - PARRISH'S COELOGYNE 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 parishii needs the light level of 15000-50000 lux. Strong air movement should be ensured all the time. Cloud cover in combination with summer monsoons indicates that plants require shading from spring to autumn end, this light should be filtered and dispersed. Plants should not be exposed directly to the sun, especially in the middle of the day. In nature, during the dry winter season, when the sky is clear for more than half the days of each month, the sun is strong.
Temperature:
In summer, the average day temperature is 18-23 ° C, night 13-14 ° C, with a daily amplitude of approx. 5 ° C. Plants can be adapted to warm afternoons if high humidity is maintained, air movement is strong and cooling down in the evening. The average winter temperature is 8-9 ° C during the day and 2-3 ° C at night, with a daily amplitude of 7 ° C.
Humidity:
Parrish's Coelogyne needs the humidity of 85-95% for most of the year, from late autumn to spring falls to 75-80%.
Too dry air has a negative effect on the development of the plant: its growth is inhibited, and the leaves begin to turn yellow and dry out. The higher temperature, the higher the humidity should be, and the higher the humidity, the more often and longer it is necessary to ventilate the room where the plants are contained, otherwise the probability of rotting and various kinds of fungal diseases.
Substrate, growing media and repotting:
Coelogyne parishii grows best attached to pieces of tree fern or cork, but during the summer hot and sunny days it requires high humidity and several waterings during the day. The plants, however, are usually planted in shallow containers or baskets which allow the drooping racemes to hang over the sides (but they do well enough in pots), because for most growers it is difficult to maintain high humidity in the summer planted on rootstocks. The substrate should be loose, quickly draining water, but at the same time it must stop a large part of it, not soaking excessively and not decomposing too quickly. A mixture of chopped tree fern fibers mixed with 10% perlite, 10% cut sphagnum moss and 10% charcoal gives great results for most growers and this medium undergoes very slow decomposition. It is also possible to use a fir bark, if humectants are added, but the constantly moistened bark decomposes quickly and the plants need to be replanted more often.
The plant should be replanted as little as possible, because this shock may even stop flowering for the next three years, which is why slowly decomposing substrates are so desirable. Some believe that as long as the substrate is still loose and well-aerated, it is better to simply cut old, drying pseudobulbs than to replant the plant. However, if replanting is necessary, it is best to do it when new roots begin to grow. This will allow the plant to adapt to the new substrate in the shortest possible time.
Watering:
From late spring to autumn rainfall is very abundant, but in autumn they disappear and the 3-5 month period of drought begins. During intensive growth, the plants should be watered profusely, but the substrate should not be allowed to spread or become damp. When new growths reach maturity in the autumn, the amount of water should be slightly reduced.
Watering is directly dependent on the temperature of the content, the higher it is, the more often it needs to be watered. When watering, excess water should flow freely from the pot, since stagnation of water both inside the pot and in its pan can very quickly lead to rotting of the roots and the lower part of the plant.
Fertilizer:
During the active growth, the plant should be fertilized every week 1/4-1/2 of the recommended dose of fertilizer for orchids. Many breeders prefer to use sustainable fertilizer throughout the year, but there are also those who use fertilizer with increased nitrogen content from spring to mid summer, and then, in late summer and autumn, begin using a fertilizer with a higher content of phosphorus.
In order to avoid the accumulation of mineral deposits during the period of strong fertilization, it is recommended to rinse the containers approximately every month. Flushing is especially important where the water is highly mineralized. First, normally, the plant should be watered to dissolve the accumulated salts, and after about an hour, rinse the substrate with water equal to twice the volume of the container.
Rest period:
In nature, rains are weak for about 3 months during late autumn and early winter, but additional moisture is available in the form of frequent mists, dew and drizzle. Therefore, watering plants in breeding should be limited, but they should not be allowed to stay dry for a long time. In most cases, poor watering every 3 weeks with occasional fogging will meet the requirements of plants. A cool and dry resting period is necessary for healthy growth and flowering, but it does not have to be as long and severe as the rest period occurring in nature. Low temperatures (about 9-10 ° C) along with the restriction of watering for about 3 months are enough to meet the rest requirements.
