Starting from young trees, through annual pruning, the backbone skeleton with vigorous growth, uniform distribution and similar thickness is gradually cultivated. In the first and second years of planting, the crown is shaped as soon as possible by coring and cutting short, leading the way with strong branches and accelerating the growth of branches with strong buds. You can trim it at any time. However, in order to avoid damaging mulberry and affecting its yield and quality, the best pruning time is in winter and spring and before the bud leaves germinate in early spring. Winter is more suitable for large-scale comprehensive pruning, and the main reason for early spring is to supplement and prune unused leaves in winter.

The first method is summer cutting, which generally cuts off all the above-ground parts of mulberry trees after harvest. This is a method to cultivate new fruiting branches. The second method is thinning and accelerating germination, mainly in early spring. New buds will be erased from the seedlings, and new buds that grow too close will become thinner. Mulberry pruning can make branches less slender, and it is also convenient for farmers to pick mulberry leaves and fruits. They can easily pick them on the ground without climbing trees. I think this is one of the benefits of mulberry pruning.

When pruning, it is mainly to remove some dense branches and excessive inflorescences on branches. It is also necessary to cut off some branches that grow too long to prevent them from consuming too much nutrition. Concentrate nutrition on branches with strong fruiting ability to provide sufficient nutrition for branches to blossom and bear fruit. The length of pruning depends on mulberry varieties and branch lengths. For varieties with short branches, dense internodes and high germination rate, pruning should be short, and vice versa. Generally, 1/3, 1.5m-5m branches with a length greater than 1/6 are cut off, and the non-lignified parts are subtracted from lm.

Wait until the next spring to germinate, and then prune. At this time, the main object of pruning is the top of plant branches, that is, the head. The purpose of this is to suppress the apical dominance of plants and let more leaves and buds be suppressed on the branches of plants.
