High temperature in summer and low temperature in winter are not suitable for fertilization. Fertilization should not be excessive and not out of date. Watering should be neither dry nor watered, once watered thoroughly when dry, and no waterlogging is left on the basin. Spray water regularly to remove dust from the foliar surface. 3.

From September to November, the plant is removed from under the tree and placed directly on the platform. The pot is transferred once a week, and the management of fertilizer and water is the same as that of spring conservation.
