Big cherry grows rapidly, with loose branches and developed ducts. It is a tree species that avoids light, but the requirements for light are not too strict. The standard of retaining branches is to form a "flower shade" on the ground under the crown of the tree in the growing season, and the density of retaining branches can be greater than other tree species.

1. Tree shape: Most big cherries are spindle-shaped, with small crown and sparse layers, and are happy. The height of the trunk is about 30-80cm, and the height of the tree is controlled at 3-3.5m, which is convenient for management.

2. Pruning: Pruning of big cherries adopts a combination of winter pruning and summer pruning, with summer pruning as the main method.

The branches of big cherry are easy to be discharged from the cutting mouth, so the pruning of big cherry in dormant period is generally postponed until spring germination. It mainly removes upright branches, competitive branches, concurrent branches, overlapping branches and pest branches. During the crown expansion period, the main branches and extension branches can be appropriately shortened. The branches of big cherries often have 3-4 branches, commonly known as "three-pronged branches" or "four-pronged branches". Generally, the treatment method is to keep 1, cut off 1 and remove 1-2.

Big cherries should also pay special attention to pulling branches. Branching refers to spreading the upright branches and branches with smaller opening angles by means of bracing in the growing season. Another method is thin branches, which means removing branches from the bottom. Big cherry is different from other tree species in thinning large branches, so it is best to "leave branches" for pruning to prevent the glue from losing water and weaken the tree.
