Pruning of Japanese maple

The purpose of pruning Japanese maple trees is to prevent virus damage by removing dead branches, broken branches and branches affected by diseases and insect pests, and it can also cut off weak and useless branches.

Methods and key points of pruning Japanese maple

1. During the vigorous growth period of the Japanese maple, only branches with a length of more than 30 to 50 cm need to be retained, and other branches and newly grown branches can be trimmed. This can ensure the overall length of the crown, and the evenly distributed branches can enhance its ventilation and light transmission.

2. When pruning the Acer palmatum, it is best to use professional pruning tools. Use potassium permanganate to disinfect the tools before pruning. The pruned branches can be coated with agents such as carbendazim to avoid infection by pathogens. The temperature must be controlled during pruning. When the temperature is too high or excessive, it will be detrimental to the growth of new branches.
