Pittosporum likes warm and humid maritime climate, likes sunshine, is resistant to shade, salt and alkali, wind and moisture, and has low requirements on soil. It grows best in alkaline or neutral loam. Strong germination and pruning resistance. Potting should use fertile garden soil and a small amount of bone powder as base fertilizer, and mix well to make culture soil. If the cultivated plants are to be cultivated into spheres, they should be pruned from the seedlings. When the plant grows to more than 30 cm, it should be shrunk to about 20 cm to promote the germination of lateral branches. When the lateral branches are elongated, it is necessary to pick the heart in time, remove the sprouting branches at the base, and keep the branches neat and symmetrical.

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.
