The Basics of Tree Trimming

When a tree or shrub in your landscape becomes overgrown, it can cause damage to nearby structures and interfere with power lines. It can also affect a tree’s overall health. Tree trimming is a great way to promote proper growth patterns and remove any dead or unhealthy branches.

When done correctly, it can strengthen the structure of a tree and prevent damage during storms. In addition, it can improve a property’s appearance and help maintain an attractive yard. Whether you’re a homeowner or a professional, it’s important to understand the basics of tree trimming so that you can get the most out of this maintenance practice.

Depending on the type of tree and the extent of its growth, trimming can be performed either manually or with mechanical equipment. For example, hand shears can be used to cut small branches and twigs, while lopping shears are often used to make larger cuts. Regardless of the size of the cutting job, it is important to follow proper safety protocols and use the appropriate tools for each task.

For large trees, a professional tree trimmer can be very helpful to ensure the safety of people and property. This may include removing branches that are too close to power lines, reducing the risk of falling debris or limbs during storms, and maintaining an attractive appearance. A professional can also help ensure the proper health of a tree by addressing issues like nutrient deficiency and insect infestations.

The majority of tree trimming is done by removing dead or diseased branches and thinning the crown. These actions can improve air flow, allow light penetration to the ground and interior leaves, and stimulate new growth. Thinning is also important for preventing the buildup of water and carbon dioxide in the trunk, which can lead to damage or failure.

A common mistake is over-trimming, which can result in unsightly “broccoli” trees that are prone to breaking in storms. Topping is another undesirable pruning technique that should be avoided, as it reduces a tree’s natural shape and forces weak new growth that is more prone to damage.

Before beginning any trimming job, it is important to carefully inspect the tree for safety hazards. Inspect the trunk condition and limb strength, as well as the surrounding vegetation for signs of stress or problems. Be sure to avoid climbing large or tall trees or working near power lines, and don’t prune branches that are too close to the ground.

Once you’ve determined the general scope of the work, it is time to select the correct cutting tool and location. When removing a branch, it’s important to make the cut just outside the branch collar — the wide area that encircles the base of the trunk. This will protect the bark from damage and encourage wound closure. Avoid cutting flush with the trunk, as this can cause rot and insect invasions. Instead, cut at an angular, downward angle where the branch meets the trunk. This will create a callus, which is an effective barrier against insects and diseases.
