1, the cutting time is in late spring and early summer, which can be combined with pruning. The cuttings are mostly 1 year semi-lignified intermediate branches.

2. After cutting, in order to prevent the milk from flowing out too much and affect the survival, the wound should be sealed with cement or plant ash in time. The length of cuttings is based on three buds. Cut off the lower leaves, close the upper two leaves, and tie them with thin plastic ropes to reduce the evaporation of seedling leaves. Then, plant it in a bed based on plain sand or frog stone.

3. Keep the humidity of seedbed high after transplanting, but don't accumulate water. The suitable temperature is 18-25℃. Sprinkle water on the ground frequently, improve the air humidity, and do a good job in shading and ventilation. It will take about 2-3 weeks to take root and sprout. Put a little shade after potted plants, and then gradually increase the light after the new buds germinate.
