In terms of time selection, it is best to choose June-July. The surrounding humidity is high and the survival rate is high.

Second, the method and process

1. Leaf: It is considered that petiole cannot produce adventitious buds. Hypertrophic leaves or terminal buds with buds at the base can be selected, so that new plants can be formed and new individuals can be developed in the later stage. You can use a whole piece or cut it in half with sharp scissors. 2. Substrate: The substrate required to be used is transparent, which is conducive to drainage and ventilation, and can also ensure nutrition. In order to achieve this effect, garden soil, humus soil and river sand can be used in daily use at the ratio of 5:2: 1. Disinfect before use to effectively avoid bacterial infection in the later stage. 3. Cutting: insert the leaves into the substrate, and the bud tip can be exposed on the substrate, about 3cm. It can be covered with a piece of glass, which can effectively prevent water evaporation. 4. Later stage: After completion, keep the room slightly wet and spray some water on the leaves. Generally, it can take root in 30-40 days.
