What kind of climate environment is best for growing Chinese orchids (Cymbidium)?
The best climate environment for growing Chinese orchids (Cymbidium)
Any plant can only survive and grow under certain climate conditions, and the climate conditions for the survival and growth of various plants differ from one another. The best climate conditions for growing Chinese orchids (Cymbidium) are:
(1) Temperature.Cymbidium sinense、Cymbidium ensifolium25-30℃;Cymbidium goeringii、Cymbidium faberi。Cymbidium kanran18-24°C.
(2) Light. In summer and autumn, shade 75% on sunny days; in winter and spring, shade 50% on sunny days; a UV index of 5 or above will scorch the leaves.Cymbidium ensifolium、Cymbidium kanranare relatively sun-loving, while other orchids are relatively shade-loving. But if there is no exposure to a small amount of sunlight, then all orchids will have low flowering and sprouting rates.
(3) Relative air humidity 80%-100%.
(4) Absolute soil humidity 80%-100%.
(5) Day-night temperature difference of 6-12°C. That is, it is best to have warm days and cool nights.
(6) Wind. Southeast wind, force 1-2.
Variousorchidsdiffer slightly in their original growing environment and growth habits, so their optimal climate conditions for growth also differ slightly.
Cymbidium sinenseoriginally grows south of 26 degrees north latitude (at higher altitudes the latitude is lower, and at lower altitudes the latitude will be somewhat higher); for example, in southern Fujian at 27 degrees north latitude, some lower-altitude places also haveCymbidium sinensegrowing there. Therefore, Cymbidium sinense likes relatively higher temperatures, and even 30°C is still a fairly good growing temperature for it. Its light requirements are relatively low, and it does not need overly intense light.Cymbidium ensifoliumsuch as Daqinglan, likes relatively strong light, and scorching under direct sunlight is not as severe as with Cymbidium sinense; some can be placed on a balcony for a long time and still grow well.Cymbidium kanrangenerally grows in higher-altitude places and is relatively tolerant of severe cold; Cymbidium kanran still grows at 32 degrees north latitude.Cymbidium goeringiigrows at altitudes from above 400 m to 1000 m, and at 32 degrees north latitude there is stillCymbidium goeringiigrowing, so Cymbidium goeringii is also relatively cold-tolerant. Cymbidium goeringii and Cymbidium kanran both like a large day-night temperature difference and also need relatively strong light. Cymbidium sinense, on the other hand, fears strong light the most; when exposed to direct sunlight, its leaves will be scorched within a few hours, and after a few days scorched reddish patches appear, with no way to recover. For various orchids, if the leaves temporarily turn yellow due to lack of water or poor ventilation and it is not too serious, once the climate conditions are good they can slowly recover and turn green again and continue to grow, so there is no need to worry.
