Chestnut tree pruning

Pruning chestnut trees can reduce the number of large branches, control the tree crown, increase and stabilize the number of fruiting branches, make them bear fruit in three dimensions, that is, full-bore fruit, overcome the phenomenon of alternate years, and achieve high and stable yields.

Chestnut Tree Pruning Time

Chestnut trees are very resistant to pruning and can be pruned all year round. Pruning is done according to the growth conditions, with different pruning focuses in different seasons.

How to prune chestnut trees

The most important thing when pruning chestnut trees is heavy pruning, which is divided into three steps:

Chestnut tree pruning precautions

1. Chestnut trees are mainly pruned during the winter dormancy period. At this time, the plant grows slowly, and nutrients are transported and stored by the branches, leaves, and roots. After entering spring, the tree sap begins to flow. Pruning too early or too late is not suitable, as it will affect its normal growth.

2. Pruning chestnut trees in winter can increase ventilation and light transmittance, enhance photosynthetic intensity, accumulate more nutrients, further enrich the male flower primordium in the bud, help it germinate better, and increase the number of female flowers.
