Best handled in late winter, tree trimming keeps your trees healthy and your landscape in top shape. Learn how to safely and effectively prune your trees and implement the best tree trimming practices.
Is tree trimming necessary?
Tree trimming is necessary to prevent old or weak branches from falling and causing injury or damaging property. Here are a few reasons why you should trim your trees each winter.
Safety—By removing broken and dead tree limbs before they fall, you avoid the potential for injury—either to yourself or a passerby. You also prevent tree limbs from falling and damaging your car or house. If you notice a dead tree branch at any time of year, cut it down or have it removed.
Appearance—Another reason to trim your trees is to keep them looking beautiful. A good rule of thumb is to trim trees according to their natural shape rather than trimming them to grow in an unnatural shape or form.
Tree Health—When done right, trimming a tree to remove diseased or dead limbs is an effective way to keep your trees healthy. Annual tree trimming encourages proper growth and allows trees to maintain a strong structure. Even removing a few leaves and smaller branches can improve tree health by allowing more air and sunlight to filter through.
When is the best time for tree trimming?
The best time to take on this task is in the late winter or early spring, after the coldest days have passed and just before new buds are about to form. However, you don’t want to trim your trees when the weather is extremely cold.
Additionally, it’s not a great idea to prune your trees when it’s raining or damp since moisture can breed bacteria and disease. For the best results, wait until the sun is shining and tree branches are dry.
What to remove during the tree trimming process
When pruning or trimming a tree, it’s safe to remove the following branches:
Branches that cross and intersect
Low branches that get in the way of walking
Branches that block windows and light
Branches that block intersections or interfere with street signs
Branches that block or obscure your home’s entryway
Tree trimming safety tips
Since tree trimming can be dangerous, here are a few safety tips to keep you out of harm’s way during the process.
If branches have fallen on a power line or if your pruning requires you to work in close proximity to power lines, call in professional help.
If a tree branch is greater than 4 inches in diameter, it may be more difficult to remove. Call in an expert if this is the case.
Any time you feel uncomfortable when trimming a tree, call in an arborist or other tree trimming professional. Ask neighbors and other locals for a recommendation and research different tree trimming services online. Many companies will offer free estimates before helping you out.
How to: tree trimming
Before trimming a tree, gather the necessary tools and make sure all supplies are clean and sharp. Rinsing them with warm water and soap and rubbing them with a good oil stone (for sharpness) should do the trick.
Pruning or lopping shears
Chisel or sharp knife
Single-pole ladder or extension ladder
Before beginning the tree trimming process, put on gloves and protective eyewear to prevent injury.
Climb up a single-pole ladder or extension ladder to begin visual inspection of the tree limbs from the top of the tree. Make sure it’s planted firmly on the ground and stable against the tree. When trimming limbs, always work your way downward and make sure there’s nobody beneath you that could get hurt from falling debris.
Before sawing off an entire tree limb, make a ¼-inchnotch cut with a hand saw two to three feet away from the trunk (this keeps the bark from splitting during the next cut).
Just outside the notch cut, use a hand saw or small chainsaw to make a relief cut completely through the branch. This removes the weight of the branch and helps you make the final cut without the branch splitting and falling.
Next, identify the branch collar, or the area that grows from the stem tissue at the bottom base of the branch. Never cut into the branch collar—this part is responsible for forming scar tissue and healing the tree after the cut.
