1. The growth of drooping branches is more likely to weaken after lemon fruit picking. You can retract and cut off the drooping parts year by year to raise the position of the branch group to continue bearing fruit. Large upright branches with many tops can be treated according to the principle of sparing strong branches on strong trees and sparse upright branches on mediocre trees. Strong ones should be thinned out and weak ones should be shortened. Through pruning, the fruit-bearing tree is always in a balanced state of vegetative growth and reproductive growth, and always maintains a certain high-yielding tree shape, thereby extending the economic life of the tree. For adult trees that were neglected in shaping and pruning in the early stage, or where the upper part of the crown is strong and the lower part is weak, resulting in closed canopy, pruning methods such as thinning branches, sawing large branches, severe retraction, opening skylights, and cutting off riding branches will be used as appropriate to reduce the canopy of the tree. , restore tree vigor as soon as possible and generate yield.

2. Lemon trees are pruned at different times. In my country's lemon-producing areas, lemon pruning can be carried out all year round, but the focus and purpose of pruning are different. Pruning in winter and spring is carried out after the lemons are harvested and before the spring shoots germinate in the second spring. In areas without frost damage, pruning can be done after harvesting in conjunction with orchard clearing, and pruning should be early; in areas with frost damage, pruning can be done after the temperature rises in spring and before spring shoots germinate. Old trees, weakened trees, and trees that need to be re-pruned to promote their shoots can also be pruned back during shoot growth in spring and summer.
