How and when to prune Castanea henryi

Pruning of Acer truncatum was carried out after the leaves fell, when the growth almost stopped. Pruning can reduce the damage to it, save a lot of nutrients, and make it better through the dormant period. Pay attention to pruning to avoid the growing period, otherwise it will easily affect the overall tree potential.

Second, the pruning method

1. Seedling pruning: when the seedlings grow to 30-50 cm high, they should be pruned. It is enough to leave a trunk at ordinary times, and cut off the side branches and sprouting branches with low branching points from the base. For each main branch and lateral branch, short branches should be selected to make their overall distribution more reasonable. 2. Pruning during dormancy: when pruning Castanea henryi during dormancy, weak branches, overlapping branches and cross branches are mainly pruned. Some overgrown branches germinated during the growth process should be cut short to make the overall plant type consistent, so that they can recover faster.

Third, the pruning precautions

When pruning Acer truncatum Bunge, special pruning tools should be used. Gardening scissors are the best and sharper, which can promote the wound to be smoother and conducive to recovery. Management should be strengthened after pruning, and the wound should not be soaked in water, otherwise the wound will rot easily and affect the recovery. In addition, proper heat preservation should be done after pruning during hibernation, especially potted plants to avoid frostbite.
