The Basics of Tree Trimming

Tree Trimming is a common landscaping practice that can help prevent trees and shrubs from overgrowing their spaces, obstructing views or interfering with power lines. It is also performed to promote plant health, reduce the risk of damage and disease, and enhance a landscape’s aesthetic appearance.

Most trimming is done to control growth, improve structure and form, remove dead wood and limbs, repair storm damage, and keep clearance for buildings, cars, pedestrians and utilities. Pruning also helps increase energy efficiency and to encourage proper tree development. It is often done on ornamental and fruit trees. Generally, deciduous trees need to be trimmed more often than evergreens.

The type and frequency of pruning depends on the species of tree, its location in a landscape, and climate conditions. Most trimming is done annually on young trees and occasionally on older ones. It is most effective if conducted during the dormant season, when pruning does not interfere with the tree’s ability to grow and repair wounds.

Professional arborists know how to thin a tree for light without removing healthy limbs or creating stubs that can invite pests and diseases. They are also trained to prune in a way that promotes proper branch structure, and they understand the relationship between crown vigor and overall tree health.

Thinning cuts are usually used on younger trees to allow more air to circulate and to help them grow stronger. Thinners also reduce wind resistance and can be used to remove diseased or problem branches, reduce height or width, and promote proper shape and form. Heading cuts are generally used on older or mature trees to promote a more compact, dense canopy, or to reduce a tree’s overall size and weight. This type of cut can also be used to remove dead limbs, and to remove water sprouts, sucker growth or other objectionable new growth.

A tree’s main stem, or leader, should be kept clear of competing branches to avoid structural weakness. Proper pruning should also prevent the formation of rubbing or crossing branches and the growth of large limbs that could fall and cause damage. Water sprouts, or suckers, should be removed as they can detract from the beauty of a tree.

The final step in the pruning process is to close the cuts and seal them with a proper wound dressing. Wounds that are not sealed properly will not heal and can lead to future problems, including insect infestation, decay and other issues. When cutting a branch, make sure to never leave a stub or remove the branch collar. The branch collar is the wide area at the base of a branch where it joins the trunk of a tree.
