How to prune pear trees in autumn?
Autumn pear trees are mainly divided into winter scissors and spring scissors. Winter pruning is to cut off residual branches, useless branches, repeated branches and cross branches, so that they can store more nutrients in winter; Pruning in spring is mainly about pruning branches and leaves, shortening the branches that are too strong and cutting off the weak branches, so as to promote the growth and flowering of defective buds in the later stage and improve the quality and yield of fruits.
