Pruning is usually carried out in early winter or early spring 1 1 to 12. If the branches are too long, prune them in June and July 1 time. Pruning in spring (or in winter) should remove dead branches and diseased branches in the crown, while pruning dense branches and weak branches to maintain perfect plant shape and promote the growth of new buds in that year. If pruning is to make the whole tree feel soft, it is limited to cutting off the branches of 1/3.
