What are the pruning sequence and precautions for shaping and pruning garden flowers?

Pruning sequence and precautions for shaping and pruning garden flowers (1) Pruning sequence For pruning individual branches, follow the principle of "look first, cut second, check third." Before pruning, first observe the plant's growth vigor, branch distribution and crown shape, and especially consider perennial branches carefully before making a cut. When cutting, work from top to bottom, from the inside out, first rough pruning and then fine pruning. Begin with thinning: first remove dead branches, densely growing branches, overlapping branches and other such branches, then shorten the remaining branches, leaving the bud at the cut in the direction where you want new growth. When renewal pruning is needed, first deal with large branches, then medium branches, and finally small branches. After pruning, check whether the work was reasonable and whether any cuts were missed or made incorrectly, so they can be corrected or supplemented.

(2) Pruning precautions When pruning, all tools and machinery must be flexible and secure to prevent accidents. When pruning street trees, pay attention to high-voltage lines, and prevent large sawn-off branches from injuring pedestrians and vehicles.

When removing buds and suckers, do not tear the bark, so as not to affect the growth of the tree.

The cutting edges of pruning tools must be sharp. After pruning diseased branches, treat them with a sterilizing agent (10% benzalkonium bromide or 2% copper sulfate, etc.), and then prune other branches to prevent cross-infection. Collect and burn diseased and pest-infested branches that have been pruned off in a timely manner.
