Peach or apricot trees planted in the courtyard can be pruned naturally and happily, but the trunk height should be increased appropriately (1 m is appropriate).
The key points of pruning peach trees and apricot trees in winter are: thinning the upright vigorous branches, over-dense branches, thin weak branches, overlapping branches, cross branches and back branches, so as to improve the illumination in the inner hall of the crown; Young flourishing trees should open main branch angles to ease tree vigor and promote flowering; Adult trees with excessive flowers should cut off some buds properly, control the yield, improve the fruit quality and stabilize the tree.
2-3 times of summer pruning are needed from June to September to improve canopy illumination.
