Propagation is generally carried out by seeding. After flowering, it is easy for pollination to bear fruit. The fruit matures from October to November, and is sown immediately after harvesting or sown in April of the following year, and sown with large seeds. Sow in pots, keep the pot soil moist, and seedlings can emerge in 2 to 3 months. In the spring of the second year, the seedlings can be divided and planted in small pots.
