Breeding mode

Sowing, cutting and grafting are the main breeding methods. Cherry blossoms are cultivated by sowing. Be careful not to dry the seeds. They should be sown at harvest or in the spring after wet sand accumulates. Grafting cultivation 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.

Sowing: sow cherry seeds after harvest, don't dry them. Because the seeds are dormant or stored in the sand in the spring of the following year, the seedlings are cultivated for grafting.

Cutting: use one-year stiff branches in spring and young branches in summer. Cutting can be treated with NAA, and the seedbed needs shading, moisturizing and ventilated substrate, so the survival rate is high.
