Coelogyne mooreana also called as Moore's Coelogyne, Coelogyne mooreana f. alba, Coelogyne psectrantha, is a species of the genus Coelogyne. This species was described by Robert Allen Rolfe in 1907.
IDENTIFY COELOGYNE MOOREANA
Coelogyne mooreana is native to Vietnam. These plants grow in highland motane cloud forests at an altitude of 1200-1300 m in the Lang Biang mountains near Dalat, about 240 km northeast of Ho Chi Minh City.
It is a medium sized, cool growing species, which reaching a height of 30-45 cm, with clustered, ovoid, bluntly angulate, slightly furrowed pseudobulbs carrying 2, apical, narrowly linear-oblanceolate, plicate, 7 nerved, gradually narrowing below into the petiolate base leaf.
Moore's Coelogyne blooms on an erect, terminal, 37.5 cm long, racemose inflorescence that has from 3 to 8, fragrant flowers arising in the spring and early summer on a newly emerging pseudobulb growth. The flowers are 7-10 cm in diameter. They open simultaneously and are evenly distributed on the flower stalk. Parts of the flower are snow-white except for the gold-yellow spots on the central lip of the lip.
COELOGYNE MOOREANA 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 mooreana needs a light level of 15000-25000 lux. Strong air movement should be ensured all the time. They need for shading from spring to autumn, but the light should be as much as the plant can bear without burning the leaves.
Temperature:
It is a plant with moderate thermal requirements. The average temperature of the summer day is 25-26 ° C, night 17 ° C, which gives a daily amplitude of 6-8 ° C. In spring, the average daytime temperature is 27-28 ° C. During winter, the average daytime temperature is 25-26 ° C, the night it drops to 12-13 ° C, and the daily amplitude increases to 13-14 ° C.
Humidity:
Moore's Coelogyne needs the humidity of almost 85% in summer and early spring, falling to 60-70% at the beginning of winter.
Substrate, growing media and repotting:
Coelogyne mooreana can grow attached to pieces of tree fern or cork, but during the hot and clear summer days it requires high humidity and several waterings during the day. These plants are usually planted into flat containers or baskets, using a loose, fast-drying substrate. Small or medium bark, tree fern fibers or mixtures with various additives such as charcoal, perlite, or cut sphagnum moss are often used as substrates.
When the plant grows out of the basket, it can be completely repotted to a larger one without disturbing the roots. This is important because this species do not like repotting and after repotting or dividing they need recover for 2-3 years. It is recommended cutting old pseudobulbs instead of repotting, if the substrate is not very spread. If repotting is necessary, make sure that new roots are already beginning to grow. This allows the plant to rooting as quickly as possible.
Watering:
In the summer monsoon season, which lasts 4-6 months in this part of the world, there is a very large amount of precipitation. Then comes the cold, very dry period of the winter monsoon, which also lasts for several months. In cultivation, Coelogyne mooreana need to be watered abundantly during the period of active growth with easy drying between waterings. When new growths reach maturity in autumn, the amount of water gradually decreases.
Fertilizer:
During the period of strong growth, the plants should be fertilized every week with 1/4-1/2 of the recommended dose of fertilizer for orchids. You can use of fertilizers with reduced nitrogen content in the late summer and autumn period, and increased phosphorus to improve flowering in the next season and strengthen new growth before winter.
To avoid the accumulation of mineral deposits during periods of strong fertilization, it is recommended to rinse the containers approximately every month. Rinsing is particularly important where the water is highly mineralized. First the plant is normally watered. After about an hour, when the accumulated salts are dissolved, the substrate should be rinsed with water equal to twice the volume of the container.
Rest period:
When new growths reach maturity in autumn, the amount of water supplied decreases gradually, and in the winter only small occasional watering or morning spraying is enough. The amount of water can be increased when we notice the drying of the tips of the youngest leaves or when the pseudobulbs become wrinkled excessively. Leaves on older pseudobulbs may naturally die in this period, but the ends of the youngest should remain green. A small wrinkle can also occur on the newest pseudobulbs. Over wrinkles indicate a shortage of water, while its lack, i.e. excess water, may cause the Coelogyne mooreana to not bloom. Fertilizers also reduce or completely stop before the beginning of abundant watering in the spring. When new roots begin to grow in spring, this is a sign to gradually increase the amount of water supplied.
