The overwintering spring tube of white orchid

The white orchid is one of the most popular fragrant flowers with soft and green leaves, white flowers and fragrant orchids. It likes warmth and fear of cold, so overwintering and early spring management is the key to the cultivation of white orchids. The main points are as follows:

Third, if there is a stove or unstable temperature in the room, plastic film can be used to cover the tree crown to prevent smoke and dust, and to stabilize the temperature and humidity, but attention should be paid to keeping the tuyere in order to avoid excessive humidity, blocking the air and promoting mold reproduction.

Fourth, the flowerpot had better have a fixed position, do not often move, because the white orchid is quite sensitive to the change of the environment, especially after the bud is pregnant, it is easy to cause the bud to fall off.
