Winter is a time when trees are vulnerable, and there are several simple but effective ways to kill a large tree. First, by applying high-concentration salt water to the roots of trees, the salt will take away water from the plant cells, causing dehydration and death. Herbicides can even be added to enhance the effect. Secondly, circumferential cutting of tree trunks is also a common method. By peeling off the bark in the center of the trunk, it blocks the transmission of nutrients and prevents the tree from growing normally. Furthermore, chemicals, such as hot solutions of lime powder, caustic soda or washing powder, can be used and injected directly into the roots to cause thermal damage and death.

However, for tree maintenance, pruning and shaping are completely different concepts. Proper pruning helps trees grow healthily. Trees should be reshaped and diseased branches, cross branches, etc. should be removed. Shrubs should maintain a full distribution of branches and leaves. Hedges should be pruned regularly to promote branching. Ground covers and climbing plants should be promoted to cover and entangle. When pruning, the incisions should be located at the nodes and smooth, and large branches should be cut in sections to ensure safe operation. During the dormant period, pruning focuses on shaping, while during the growing period, the main focus is on adjusting the tree's vigor to avoid damage during the flow season.

In general, although there are these methods of quickly killing trees, in actual operations, we should pay more attention to the health maintenance of trees. Through pruning and proper management, the trees can also survive in winter. Thrive.
