How to grow orchids? Linghai Lanyan summarizes the orchid-growing experience of Lingnan, Guangdong

"Linghai Lanyan" is the orchid-growing experience from the Lingnan region of Guangdong. It proposes a watering method of 6 cases for exemption, 4 cases for increasing, and 5 cases for reducing:

6 cases for exemption: exempt when it rains, exempt when the sky is overcast, exempt when it snows, exempt when about to change the soil, exempt when about to apply tea seed cake or tobacco stems (that is, when about to apply pesticide), exempt when about to repot.

4 cases for increasing: increase when the heat is too intense, increase when the north wind is too strong, increase when in a location with much sun, increase when the pot is small and the orchids are thriving.

5 cases for reducing: reduce when the weather has frequent rain, reduce when the soil in the pot has broken down, reduce when in a location with much shade, reduce when the pot is large and the orchids are small, reduce when the orchid crowns turn black and spots appear on the leaves.
