Summer pruning is also called growth pruning. Evergreen fruit trees have no dormancy period and can be pruned in all seasons. Summer pruning of deciduous fruit trees is generally carried out from May to September. In summer, because trees store less nutrients, new leaves will be reduced due to pruning, and the same amount of pruning has a greater inhibitory effect on the growth of trees, so pruning is generally lighter. Used properly, it can play the following roles:

(1) Pruning in summer can improve fruit setting rate, adjust the contradiction between reproductive growth and vegetative growth in time, promote flower bud differentiation and fruit growth, and improve fruit quality.

(2) Pruning in summer can promote the growth of secondary branches, strengthen branches, cultivate fruiting branches, regulate crown and speed up shaping.

(3) Pruning in summer can remove overgrowth and overgrowth in time, and artificially reduce nutrient consumption of trees.

(4) Pruning in summer reduces too many wounds during dormancy, avoids infection caused by difficult healing, and also reduces the outdoor work times of fruit farmers in frozen winter.

In a word, through pruning in summer, we can achieve the purpose of managing prosperity, slowing down the trend, flowering early, bearing fruit early and bearing good fruit while minimizing the loss and injury of branches and leaves.
