1、 Sowing and propagation

1. Seed selection: the most important step of this breeding method is seed selection. It is better to use plump seeds that have not been harmed by diseases and pests. They not only germinate faster, but also have a high survival rate

2. Treatment: after selecting seeds, it is also very important to carry out germination treatment, because its seeds are very hard and not easy to germinate. Before planting, the selected seed shell shall be removed and soaked in warm water for one day. The germination time does not need to be too long, otherwise it will rot

3. Sowing: prepare flower pots of appropriate size and put loose and breathable soil into the pots. Finally, sprinkle the treated seeds into the soil, sprinkle some thin soil on the seeds, and wait for buds after proper watering

2、 Cutting propagation

1. Time: because it likes a warm growth environment, cutting should be carried out from April to may, which is easier to survive

2. Branch selection: cut a hard branch with a length of about 15-20cm from the mother plant, with 2-3 leaves on the top of the branch

3. Cutting: use rooting powder to treat the incision and then insert it into the soil. After cutting, it needs appropriate shade and keep it slightly wet. It will grow roots in almost two months
