Watering should be dry and wet during the growth period, and it is appropriate to topdressing with fermented and decomposed dilute fertilizer water, and apply it 1~3 times in spring and autumn respectively. In summer, you should always spray water on the leaves to keep their luster. When the temperature is low in winter, watering should be strictly controlled and fertilization should be stopped. The northern area should be moved indoors in winter and the room temperature should be kept above 5℃.
Potted seedlings need to change pots 1 time every spring, and adult plants need to change pots 1 time every two years. When changing pots, add new culture soil, trim dead branches and replace slightly larger containers. At the same time, we should actively control the harm of scale insects.
