When is the best time to prune longan trees? Pruning time and technical tips

Longan tree pruning time

Longan trees are suitable for pruning in spring and autumn. The temperature at this time is suitable and has little impact on the wounds of the longan trees. If they are pruned in summer and winter, the recovery and growth will be affected due to temperature and light problems.

Longan tree pruning method

1. Pruning young trees

After the longan tree saplings survive, they will grow many new branches and leaves. At this time, the excessively long branches and leaves should be cut off, and the messy and thin branches and leaves should be cut off in time. This can promote the growth of the main branches. After they grow to a certain extent, the saplings can be shaped and pruned to promote the growth of branches and preparatory branches.

2. Spring pruning

Longan trees need to be pruned once in spring, which can be done in early spring. Spring pruning is mainly light pruning, so that the trees can maintain a relatively good crown and cut off useless branches and leaves. It can be combined with flower and fruit thinning to promote growth and ensure good yield and quality.

3. Autumn pruning

Longan trees also need to be pruned in autumn. Branches with growth problems on the tree should be cut off, and branches and leaves that grow too weak should also be cut off. This can reduce nutrient consumption and increase ventilation and air permeability. After the fruit is picked, diseased and insect-infested branches, messy branches, overly dense branches, and old branches can be cut off together to adjust the growth condition.

Precautions for pruning longan trees

After pruning the longan tree, it is necessary to disinfect it, which can speed up the healing of the wound. In addition, maintenance and management should be done to provide a cool, well-ventilated environment and avoid exposure to strong light. It can be moved to bright light only after it resumes growth.
