In what month does Yang Shulin prune branches?

Summer is the best season for poplar pruning. There are several reasons:

First, pruning in summer will inhibit the growth and development of poplar lateral branches and reduce the germination of lateral branches.

Second, summer is conducive to the early healing of trimmed wounds. In order to keep the poplar tree straight, it is necessary to remove the competing branches and side branches and dry them, and at the same time, the lowest branch point of the crown must be ensured (according to the growth years of the tree, the branch point should be between 2 and 2.5 meters), so it is not appropriate to over-prune, otherwise it will affect the growth of poplar. Newly planted poplar trees should sprout in time, remove the competitive branches and auxiliary branches that affect the top growth, and ensure that the trunk is straight and complete without side branches. For young trees, pruning is not suitable in rainy season to avoid wound healing and infection.
