In addition to the tree potential, the growth of branch potential should be a shortcut renewal, and generally it should be based on thinning branches. For plants with too dense branches, the internal branches, twigs and insect branches can be appropriately cut off to make them ventilated and well-distributed; Plants that grow too high and lack branches at the lower part can cut off the top of the trunk to promote the germination of new branches at the lower part of the trunk; Pruning of young trees should start from seedlings, select a trunk, and when the trunk reaches a predetermined height, carry out top grafting to make it sprout 3-5 lateral branches to form a single trunk crown.

After the flowers wither every year, all the long branches born in summer and autumn can be cut off, keeping the strong spring branches; Before sprouting in spring, all dead branches, diseased branches and dense twigs should be cut off, so that nutrients can be concentrated on the reserved branches, which can promote them to blossom more and make the trees neat and beautiful.

If the plant appears strong on the top and weak on the bottom, and the tree shape is not good, it can be appropriately shortened to promote the germination of adventitious buds and grow new branches. However, there should not be too many short nodes, otherwise it will easily sprout long branches and affect the number of flowers. After pruning and shaping, water and fertilizer management should be strengthened, and the sprouting branches at the base of the trunk should be pulled out in time to avoid consuming nutrients and disturbing the tree shape.
