What Is Tree Pruning and Why Is It Important?

What is tree pruning? Tree pruning — or tree trimming as it is known — can be a somewhat confusing term for many homeowners. Tree pruning is an essential part of overall tree health.

This post from Knoxville’s tree trimming experts provides an informative outline of tree pruning, including what it is, why we do it, and how to correctly prune your trees.

What Is Tree Pruning?

Tree pruning is trimming or removing tree branches or roots to maintain or improve a tree’s health and is an essential part of tree care. Experts usually trim trees in late winter or early spring to avoid damaging new growth.

Different Types of Tree Trimming Techniques

When considering “What is tree pruning?” we must consider the various trimming techniques arborists use. These include:


This type of trimming involves cutting branches back to the branch collar (where they meet other branches) to reduce the overall weight of the tree.


Thinning involves cutting branches all the way down to the trunk of a tree. This approach is ideal for young trees that are too dense with branches.


This trimming involves cutting branches into specific shapes for aesthetic purposes to ensure an even shape or appearance.

Crown Raising

Read on for those wondering, “What is tree pruning?” and how crowning fits into the technique. When a tree’s crown (the top part) grows too low and blocks sunlight from reaching lower portions below it, arborists use crown raising to raise those areas by removing some of the upper sections.

Why Is Tree Pruning Important?

Improve a Tree’s Shape and Size

Tree pruning is essential because it improves a tree’s size and shape. When a tree grows, its branches can become too long, which can cause stress and damage. However, it’s crucial to avoid bad practices, such as overpruning an apple tree, as this can lead to a decrease in fruit yield and negatively impact the tree’s health.

Prevents Disease and Pest Infestation

Another reason why pruning is essential is it removes diseased branches. This helps to keep trees healthy by increasing their natural defenses against insects and disease.

Manages Tree Growth 

Tree pruning can help manage the growth of trees and prevent them from becoming top-heavy, which can cause them to fall over.

Removes Dead Wood, Reducing Fire Hazards

Dead branches and leaves provide fuel for fires. Removing dead branches and leaves will reduce the risk of a wildfire spreading to your property and your family.

Opens Up Views and Air Circulation

Another advantage of tree trimming is that it opens up a tree’s canopy, bringing in light, air circulation, and room for leaves and lateral branches to grow.
