Longan can cultivate a reasonable tree shape after pruning, so that the tree body can distribute nutrients reasonably, improve the ventilation and light transmission conditions of the tree body, and prolong the fruiting life. Finally, the purpose of early fruiting, high yield, stable yield, high quality and high efficiency in fruit tree cultivation is achieved.

Within 2-3 years after planting, longan trees began to be pruned year by year. Generally, the long spring shoots should be pruned appropriately in spring, and the branches that are too dense, crossed, damaged and withered should be pruned in time. All flowers should be cut off within 3-5 years of planting to reduce nutrient consumption and promote the growth of summer and autumn shoots.

How many times does the longan tree need pruning?

The shaping and pruning of longan trees are generally carried out twice a year. One is pruning in spring, and this time it should be combined with thinning flowers and fruits. The other is autumn pruning. This time, it is necessary to combine the pruning of the crown after fruit picking to shrink the branches that are too dominant.

Pruning method of longan tree

1, young tree pruning: after the young tree of longan tree survives, it is necessary to reasonably prune the branches and leaves with messy growth and slender branches to promote the growth of main branches.

2. Cultivating mother branches: longan trees usually keep new bearing branches on the original bearing branches, which are called mother branches. Results Generally, the last mature autumn shoot was selected as the mother branch, and it was reserved after longan was harvested and cultivated into a strong branch.

3. Pruning in spring: In order to keep the longan tree in a good crown, it is usually pruned once in spring. At this time, the pruning is mainly light cutting to maintain good air permeability between branches.

Matters needing attention in pruning longan trees

Pruning young longan trees should be light rather than heavy, less rather than more. Branches that can be cut or not should be temporarily reserved as auxiliary branches for proper treatment in the future.
