How to prune Castanea henryi

When Acer truncatum is pruned in the early growth stage, the trunk climbs and reshapes, and the lateral branches are shortened. When pruning in the growth period, only the branches with a length of more than 30 ~ 50 cm are kept, and all other branches and tillers are cut off. When pruning during dormancy, all the dead branches, overlapping branches and forked branches growing on the plant are cut off.

Pruning method of Castanea henryi

In the early stage of Acer truncatum growth, the plants can be climbed and pruned to keep the crown straight. When climbing, the trunk is mainly fixed with thin wire to climb out of the required shape. Cut off the small branches by 3 ~ 5 cm, and remove other side branches and leaves to ensure the new branches grow in a Y shape.

When Acer truncatum grows vigorously, it is only necessary to keep the branches with a length of more than 30 ~ 50 cm and prune other branches and newly grown tillers. This can ensure that the whole crown is neat, the branches are evenly distributed, and the ventilation and light transmission are enhanced.

When Acer truncatum is dormant, all dead branches, diseased branches, overlapping branches and branches growing on the plant should be cut off, and the branches that have grown and germinated should also be cut off or cut off to reduce the loss of water and nutrients and ensure that the plant can store enough nutrients and grow normally.

Professional pruning tools should be used when pruning Acer truncatum Bunge, and the tools should be disinfected before pruning, generally using potassium permanganate for disinfection. The pruned branches need to be coated with carbendazim to avoid bacterial infection, and the temperature should be controlled when pruning. Too high or too high temperature is not conducive to the growth of new branches.
