Cutting is usually used to cultivate rubber trees. Combined with pruning and cutting in summer, the highest temperature during the day is about 30℃, and at night it is about 15℃, which is the easiest to take root. In winter, cuttings can be pruned by new plants that survived that year, and cut indoors around New Year's Day, and the temperature is kept above 65438 08℃. Plain clay or sand is used to cut basin soil. Plain clay is easy to fix short cuttings without lodging, but its air permeability is poor, so the basin bottom needs to be padded with drainage layer, and plain sand can be used as a pillar to prevent lodging.

In summer, it is best to choose biennial semi-lignified cuttings. The survival rate of annual cuttings in winter is low, generally below 60%. Immediately after cutting, seal with frankincense or plant ash. Cutting length is based on three buds. Cut off the bottom 1 leaf, seal the top two leaves, and tie them tightly with plastic rope or iris to reduce leaf evaporation. Keep the soil moist, often sprinkle water on the ground to increase the air humidity, and do a good job of shading. It takes about 20 days to take root in summer and two months in winter. The branches and leaves that survived the cuttings have always been fresh and tender. If the leaves are yellow and withered and the cuttings are black, they should be pulled out immediately.
