Trimming
Trimming is the most common tree maintenance procedure. Trimming trees helps control the height and spread of a tree, which can reduce stress on its base. Thinning the branches is important to open the foliage of the tree, reduce weight on heavy limbs, and help to retain the tree's natural shape.
Tree Pruning
Pruning helps to prevent disease and insect problems. Pruning should be done with an understanding of how the tree responds to each cut. Improper tree pruning could cause damage that lasts for the life of the tree or, worse, could shorten the tree's life
