Propagation by sowing usually begins in 15 months. The results are at the end of the year. Although the seeds are mature, it will take April to May to germinate after sowing. If the seeds are harvested in winter, they should be buried in sandy soil, and the seeds should be soaked and germinated in late spring before sowing. It is best to leave the seeds on the tree for overwintering. In May, when the temperature rises to about 30°C, all the seeds germinate on the tree. At this time, the best seeding company is immediately after harvesting, and the germination rate can reach 100%.
The sowing should be shallow, the depth of the nest is 2-3 cm, and the distance between the nests is about 1 square foot. Sow 4 seeds per nest, and cover with sifted household garbage powder after watering, so that the seeds can emerge. When the seedlings are unearthed, it is necessary to plan the soil to make the seedlings unearthed neatly.
