Luan trees can be pruned by trunk method. The vertical height is more than 2 meters, and the height of the lateral branches is 30 cm from the ground. In summer, the vigorous trunk should be sprouted in time, and 6 ~ 9 buds with reasonable distribution direction should be reserved. In winter, excessively long branches should be pruned once every three years.

Pruning steps of Luan tree 1, trunk pruning

Trunk pruning can be used for shaping and pruning Luan trees. Because Luan tree itself is difficult to grow into a straight state, trunk pruning is better. For the main vines with a vertical height of more than 2 meters, all branches exceeding this length should be trimmed, and no side branches should be left at a height of 30 cm from the ground.

2, summer pruning

In summer, it is necessary to shorten the length of reserved branches by 45 cm. For the main branches with vigorous growth, you can choose to keep about 6 ~ 9 bud points according to the distribution direction of bud points. There can be no cross phenomenon, otherwise it will affect the lighting and ventilation effect in the later stage.

3, winter pruning

In winter, you can also prune properly, cut off the long branches, and then thin the branches properly, so as to concentrate nutrients and help plants spend the winter. In summer, you need to smear buds, and leave at most three buds on a branch, so that it will not be chaotic in the later growth process.

4, three years of pruning

Luan trees had better be pruned once every three years. As time goes on, the crown of the plant will gradually grow into a ball. Only by pruning plants regularly can the shape of plants be maintained. In addition to pruning the redundant trunk, it is also necessary to prune the dry branches in time and prune the slender and weak branches.
