2. Coral trees are mainly propagated by cutting, which can be carried out all year round, especially in spring and autumn, with fast rooting and high survival rate. Choose a strong and straight stem, cut it into 8- 10 cm long and insert it in the sand bed. After 8- 10 days, the roots will grow out, and the roots are 2-3 cm long, so you can plant potted plants.
3. Coral trees change pots every spring and add fertile and well-drained humus soil and coarse sand mixed soil. Keep the basin soil slightly dry during the growing period and apply fertilizer 1 time every month. If there is enough fertilizer and water, the stem nodes grow fast, the thickness is uneven, and the plant shape is not good. At the same time, long stems tend to droop and are not straight. In addition to a little shade when the light is too strong in midsummer, you need plenty of sunshine. In this way, the deformed stems are not compact in growth, green in color and good in ornamental effect. The temperature is not lower than 5℃ in winter. Before moving indoors for maintenance, just trim and reshape the plant slightly.
