Bauhinia is very adaptable. Under normal growth conditions, the main branches and lateral branches of trees planted for more than 5 years will become very dense, and many of them have lost their regeneration ability. At this time, the old branches must be cut off by re-pruning, and then the branch spacing should be adjusted to promote the growth of new branches.
dilute
Usually, the leaves are pruned once a year after falling and before sprouting. According to the age and growth of the main branches, the aging big branches and cross branches are thinned to make the remaining main branches evenly distributed and moderately thick. When pruning in winter, you should always cut off worthless branches, such as dead branches, short branches and cross branches. Thereby promoting them to grow new branches better.
short cut
Mostly used for summer pruning. After entering the flowering period, it is necessary to shear center or pick the heart in time. If the flower is upside down, it is necessary to cut off the residual flowers and pods to avoid consuming nutrients and affecting plant growth and flower bud differentiation.
Plastic stage design method
Tree selection
The natural crown of Bauhinia is open. Because of its strong ability of budding and tillering, fast growth of branches and easy disorder, it is often used for shrub cultivation.
Shrub plastic surgery
Generally, there are 3-5 trunks, which need to be allocated reasonably. The trunking shall be carried out in an isolated place to facilitate branching. In spring, the buds are properly smeared, and about 3-4 branches are left for each trunk as the first layer of lateral branches. Pruning during hibernation can form a basic skeleton. If there are few branches, short cutting can be carried out in early spring to promote branches, or secondary branches can be promoted by coring and pruning to expand the crown.
Arbuscular plastic surgery
Arboreal pruning, generally, first determine the thickest branches as the main trunk, and then prune at 50-80cm to cultivate secondary and tertiary main branches. After 2-3 years of pruning, the tree skeleton can be gradually determined to form a plump and dense crown. After drying, pruning during dormancy. After cutting off dead branches and diseased branches, juxtapose, endogenous and cross branches. Keep some stout sprouting branches, which can be used to renew and restore the tree potential and cut off the remaining sprouting branches at the roots. It should be noted that when pruning, the old branches with strong flowers should be protected, and some long branches should be retracted.
