In autumn, the decrease of temperature makes the growth potential of seedlings weaker and weaker, and finally enters a dormant state, and deciduous trees begin to shed leaves in this process. Pruning does relatively little harm to the tree at this stage. Cut all or part of the leaves short and remove dead branches and over-dense branches. At the same time, the branches damaged by transportation will also be pruned. For flower buds differentiated in early autumn, such as plum and peach, measures such as twisting tips can be taken to control the vegetative growth of their branches and preserve nutrients for flower bud differentiation.

Note: It is best to apply some special wound healing agents to the trimmed wound, such as "Hao Guitian-Yi Shu", which can effectively prevent wound infection and accelerate wound healing.
