How to care for orchids in winter
The editor brings you the introduction of orchids, a member of the Orchidaceae family. Let's see how to care for orchids in winter!
Winter is approaching, and some novice orchid enthusiasts don't know how to care for orchids in winter. Orchids are relatively cold-sensitive, so we need to focus on surviving the winter first, and then consider how to grow orchids. First, let's understand the cold tolerance of different orchid varieties.
Generally speaking, Cymbidium is the most cold-tolerant, with no issues at temperatures as low as -7 degrees Celsius. Cypripedium is the next, with no harm at -3 to -4 degrees Celsius. Cymbidium ensifolium has slightly lower cold tolerance, usually not having problems at 0 degrees Celsius.
The worst is Cymbidium sinense. It can be damaged by temperatures slightly below 0 degrees Celsius. Therefore, it is considered safe for Cymbidium sinense to be kept above 3 degrees Celsius.
However, there is a big difference between orchids in pots and those in the wild. The cold tolerance of Cypripedium and Cymbidium in the mountains is much lower than what is mentioned here. Some information says that Cymbidium can survive temperatures below -10 degrees Celsius, but that is not possible in a pot.
Temperature: Orchids require a vernalization process to bloom, so it's not enough to just keep them in a heated room. The temperature during vernalization should be balanced and not too high or too low. It's best to keep the temperature between 0 and 10 degrees Celsius. Temperatures below -5 degrees Celsius and above 15 degrees Celsius are not conducive to the normal growth of flower buds, easily leading to僵蕾 (stunted buds) in Cymbidium and affecting the elongation of the scape.
Watering: Orchids need watering in winter, but the frequency should be adjusted according to the actual situation. Remember that the potting soil should not be wet for extended periods, and the interval between waterings should be long.
Light: There's no need to elaborate on this; it's best to provide ample light in winter.
Ventilation: Orchids enjoy ventilation and fresh air, which promote metabolism and photosynthesis.
