Shaping and pruning sequence of courtyard flowers and matters needing attention

The sequence of garden flower shaping and pruning and matters needing attention (1) the order of independent branch pruning should grasp the principles of first look, second pruning and three inspection, and check the plant growth potential, branch distribution and crown shape before pruning, especially perennial branches should be carefully considered before cutting. Cut from top to bottom and from string to string. And outside, first rough cut and then fine cut. Starting with thinning, cut off the dead branches, dense branches, overlapping branches and other branches first, and then cut the remaining branches short, leaving the cut buds in the direction in which the branches are expected to grow. When you need to retract and prune, you should first deal with the big branch, then the middle branch, and finally the twig. After pruning, check whether the treatment is reasonable, whether there are missing cuts and wrong cuts, so as to correct or repair them.

(2) pruning precautions when trimming, all appliances and machinery must be flexible and firm to prevent accidents. Pay attention to high-voltage lines when pruning street trees and prevent sawed branches from hurting pedestrians and vehicles.

Do not tear the bark when wiping buds and removing tillers, so as not to affect the growth of the tree.

The cutting edge of the pruning tool should be sharp. After pruning diseased branches, apply fungicides (10% bromogeramine or 2% copper sulfate, etc.), and then trim other branches to prevent cross-infection. The pruned branches of diseases and insect pests are collected and burned in time.
