Therefore, it is forbidden to spray water on flowers and leaves. It is best to water by soaking. Usually, water should be moderate, too much will easily lead to tuber rot, yellow leaves and even the whole plant death. In the high temperature stage in summer, water it 0 ~ 2 times a day. When the air is dry, water should be sprayed around the plants frequently to increase the humidity of the environment. Water evenly, not too wet, hot and cold. Rain must be avoided during flowering.
