Pruning strengthens and beautifies trees. Correctly pruning a tree is very important in order to avoid damaging it.

It's both art and science!



Pruning is the most common procedure for tree maintenance. Landscape trees require a greater level of care to maintain structural integrity and aesthetics. Pruning must be done with an understanding of tree biology because improper pruning can create lasting damage or shorten the tree’s life.

Reasons for Pruning

Because every branch cut may have an impact on the tree's growth, no branch should be cut without a reason. In addition to removing dead branches to improve form and safety, pruning may also be done to increase light and air penetration for plants below the tree's crown, as well as corrective and preventive measures.

When to Prune

A light, routine pruning to remove weak, dead, or diseased limbs can be accomplished at any time without detrimental effects on the tree.

Generally, pruning should take place before the spring growth flush to maximize growth and wound closure. Avoid heavy pruning of live tissue just after spring growth flush, especially on weak trees.


Disease-causing agents can penetrate pruning wounds, causing tree diseases, such as coryneum blight, to spread. Susceptible trees should not be pruned during active transmission periods.

Pruning Techniques

A mature tree may require specific types of pruning to remain healthy, safe, and attractive. The art of cleaning a tree involves removing dead, dying, diseased, weakly attached, and low-vigor branches from its crown. Raising removes the lower branches from a tree to provide clearance for buildings, vehicles, pedestrians, and vistas.

The reduction of a tree is often required to clear utility lines. The best way to reduce a tree's height or spread is by pruning the leaders and branch terminals back to secondary branches that are large enough to assume the terminal roles (at least one-third the diameter of the cut stem). Compared to topping, reduction helps maintain the tree’s form and structural integrity.

Pruning Young Trees (Thinning)

A tree's structure and form are influenced by structural pruning. When young trees receive the appropriate pruning, they will require less corrective pruning as they mature. Each cut has the potential to change the tree's growth, so setting an objective for why the tree needs to be pruned is imperative. In young trees, improving structure is the objective. Poor pruning can cause damage the tree must grow over causing the wound to stay within the tree forever.

Don’t Top Trees!

Tree branches are indiscriminately cut to stubs or to lateral branches too small to assume a terminal role by topping. When a tree is topped, its size is reduced. However, topping is perhaps the most harmful method of tree pruning. Trees that have been topped can become stressed, and they can decay. Trees topped are also expensive and do not retain their natural shape. There are alternatives to topping, including removing small branches to their origin or pruning back limbs to a lateral branch large enough to fulfill the terminal role. Sometimes, removing trees and replacing them with species more suited to the site is the best option.
