Bauhinia has strong adaptability. Under normal growth conditions, the main and side branches of trees planted for more than 5 years will become very dense, among which there are many old branches that have begun to lose their regeneration ability. At this time, we must cut off the old branches by heavy cutting, and then we can adjust the space of branches to promote the growth of new branches.
Before germination, prune once a year. According to the age and growth of the main branches, remove the old big branches and Cross branches, so that the remaining main branches are evenly distributed and moderately thick.
When cutting in winter, we should cut off the useless branches at any time, such as dead branches, short branches, Cross branches and so on, so as to promote the better extraction of new branches.
It's mostly used for summer pruning. After entering the flowering stage, it is necessary to cut short or pick the heart in time. When the flowers fall behind, it is necessary to cut off the residual flowers and pods, so as not to consume nutrition and affect plant growth and flower bud differentiation.
Bauhinia natural crown open, because of its germination and tillering power are very strong, branches grow fast, it is easy to be disorderly, often used for shrub cultivation.
Generally, there are 3-5 main trunks left, which need to be reasonably distributed and cut off from the ground to promote branching. In spring, the buds need to be wiped properly, and each trunk has about 3 or 4 branches, which can be used as the first layer of lateral branches. If the branches are rare, they can also be cut short in early spring to promote branching, or they can be plucked and pruned to promote secondary branches to expand the crown.
For arbor pruning, the thickest branch is generally determined as the trunk, and then it is cut at 50-80cm to cultivate secondary and tertiary branches. After 2-3 years of pruning, the arbor skeleton can be determined gradually to form a full and dense crown. After fixed stem, prune in dormancy period. After pruning dead, diseased, juxtaposed, endophytic, Cross branches, etc., retain some thick sprouting branches, which can be used for regeneration and rejuvenation of tree vigor. Prune the rest of sprouting branches at the root. It should be noted that when pruning, the strong old flowering branches should be protected, and the long branches should be retracted.
