Castanea mollissima can be pruned all the year round, and the pruned branches can be propagated by cutting, but special technical measures are needed, and the technology content is high, which is difficult for ordinary farmers to master.

How to prune the branches and leaves of chestnut trees

In order to promote the growth and branching of chestnut trees, three dominant branches in the first layer can be pruned in winter, the extended branches can be pruned in the second winter, and two dominant branches can be selected as the main branches in the second layer. In the winter of the third year, chestnut trees need pruning and shaping, and the main branches need to be shortened, mainly by thinning out competitive branches and twigs. If the angle is unreasonable, adjust the angle of the main branch.

Matters needing attention in pruning chestnut trees

1. Pruning of chestnut trees is mainly carried out in winter. During dormancy, nutrients are transported and stored by leaves, branches and roots. After spring, the body fluids of trees begin to flow, and the nutrients stored in roots and stems are transported to branches from opposite directions. Pruning should not be too early or too late. 2. Pruning chestnut trees in winter can improve ventilation and light transmission conditions, thus enhancing photosynthetic intensity, which is beneficial to the accumulation of photosynthetic products and the further enrichment of male flower primordia in buds, laying a good foundation for the differentiation of female flowers in bud stage and increasing the number of female flowers.
