How to prune Bauhinia

Heavy Cut

Bauhinia has strong adaptability. Under normal growth conditions, the main and side branches of a tree that has been planted for more than 5 years will become very dense, many of which are old branches that have begun to lose their ability to regenerate. At this time, the old branches must be removed through heavy pruning, and then the branch space can be adjusted to promote the growth of new branches.

Thinning

Pruning is usually done once a year after the leaves fall and before the buds sprout. Depending on the age and growth conditions of the main branches, remove the old large branches and cross branches so that the remaining main branches are evenly distributed with appropriate density.

During winter pruning, worthless branches should be thinned out at any time, such as dead branches, short branches, crossed branches, etc., to promote better growth of new branches.

Short

It is mostly used for pruning in summer. After entering the flowering period, it is necessary to prune or pinch off the top in time. After the flowers fall, the remaining flowers and pods should be cut off to avoid consuming nutrients and affecting plant growth and flower bud differentiation.

Tree Selection

The crown of Bauhinia is naturally open. Because it has strong germination and tillering ability, its branches grow fast and it is easy to grow in a tangled mass. It is often cultivated as a shrub.

Shrub-like shaping

Generally, 3-5 main trunks are left, which are required to be reasonably distributed, and the trunks are cut off the ground to promote branching. In spring, it is necessary to remove buds appropriately, and retain about 3 or 4 branches on each main trunk as the first layer of side branches. By shortening them during pruning during the dormant period, the basic skeleton can be formed. If the branches are sparse, you can also prune them in early spring to promote branching, or promote secondary branches by pinching and pruning to expand the crown.

Arborization

For tree-like pruning, generally the thickest branches are determined as the main trunk first, and then they are cut back at 50-80cm to cultivate secondary and tertiary main branches. After 2-3 years of pruning, the skeleton of the tree shape can be gradually determined, forming a full and dense crown. After the trunk is fixed, prune during the dormant period. After cutting off dead, diseased branches, parallel, endophytic, and crossing branches, some thick suckers are retained, which can be used to renew and strengthen the tree. The rest of the root suckers are cut off. It should be noted that when pruning, the strong flowering old branches should be protected, and some branches that are too long should be shortened.
