1. When pruning greenery and seedling stock, avoid haphazard, thoughtless trimming. Instead, follow the sequence of "from the base to the tip, from the inside out." First, determine the overall pruning form of the greenery stock, and then trim from the base of the main branches, gradually upwards, starting from the inside and moving outward.

2. Trees lining the same road should have a consistent value in height, and the branching heights of adjacent plants of greenery should be approximately the same.

3. For excessively thick branches, employ the segmented pruning method to prevent cracking.

4. Due to the influence of street alignment, high-rise buildings, and underground pipelines, greenery trees often suffer from phenomena such as crooked or tilted crowns. It is advisable to adjust the center of gravity early on by pruning. For branches on the weaker growth side, as long as there is no conflict with overhead wires or buildings, light pruning should be performed to achieve the purpose of softening the tree's growth and balancing its development.

5. Pruning of greenery trees and shrubs must adhere to safety operation standards to prevent accidents. At the same time, be mindful of the safety of pedestrians and nearby buildings.
