Sowing, cutting and grafting are the main breeding methods. Cherry blossoms are propagated by sowing. Be careful not to dry the seeds. They should be planted in the harvest season or the following spring after wet sand accumulates. Grafting propagation can use cherry and mountain cherry seedlings as rootstocks. Cutting in late March or budding in late August can be cultivated for 3-4 years after grafting, and can be planted after leaving the nursery. When planting, apply decomposed compost 1.5 kg -25 kg to each pit, and apply ammonium sulfate 1 kg -2 kg to each plant in July. After flowering in early spring and before germination, cut off dead branches, weak branches and long branches, try to avoid pruning thick branches and keep the crown intact.
