1, prefer the shade to direct sunlight. The optimum growth temperature of orchids is 18-30℃, below 5℃ and above 35℃, and the reproductive growth period is 5- 18℃.
2. Prefer humidity and avoid drying: Except for the period of rooting, germination and rapid growth, the water consumption at other times is less.
3, like fertility, rich in humus.
4. An environment suitable for air circulation: orchids should be kept away from gas and lampblack, and away from dusty places. Oil fume and dust attached to leaves will hinder the breathing of leaves and affect photosynthesis. Poor air circulation will cause bacteria and viruses to attach to leaves and endanger the growth of orchids.
Orchids are epiphytic or overground herbs with several or more leaves, usually located at the base or lower node of pseudobulb, in two rows, banded or rarely oblanceolate to narrowly elliptic, with a broad leaf sheath around the base and a joint. There are several flowers in the raceme, and the colors are white, pure white, white green, yellow-green, yellow-yellow, yellow-brown, yellow, red, cyan and purple.
