Long branches, diseased branches and weak branches of rich trees should be pruned in time to prevent excessive competition for nutrients. All branches that grow too badly should be subtracted. Strong branches only need 3~4 buds per branch. In addition, if you want to make the shape look better, you can also transform it into the shape you want with iron wire, or simply cut the stem short and replace it with a new shape with sprouted new branches.

After each pruning, apply carbendazim solution to the wound to prevent bacterial infection, or don't touch water to reduce the amount of watering. As long as you pay attention to the time and method of pruning, choose spring pruning, don't get wet after pruning, and take good care, the rich trees will grow more vigorously.
