1. Light: in spring and autumn, it should be placed in a sunny and ventilated place. In summer, if the seedlings need to be shaded in time, they can't accept the strong light at noon. They can be exposed to the sun at other times. Timely move to indoor maintenance in winter

2. Watering: it likes to be dry and afraid of being wet. It must not be watered too much. It can often spray water on the leaf surface. Once every two days in spring and autumn. Due to the high temperature in summer, water should be poured every morning and sprayed once in the evening. In winter, reduce the amount of water, just once a week, and spray more water

3. Fertilization: it almost does not need fertilization for its growth. Generally, it is OK to apply fertilizer 2-3 times a year. Among them, cake fertilizer should be applied once before germination in early spring. If the temperature is too high in summer, stop fertilization. When autumn comes, apply cake fertilizer once from September to October, and stop after October

2、 Common diseases and insect pests
