As trees grow up and out, maintenance and upkeep is necessary. Weak, dying and dead branches can break off during storms, damaging electrical equipment, power lines and buildings. Weaker branches also stress the tree as it diverts more resources to sustain and repair those parts.
Pruning and trimming done correctly benefit the entire tree, but done incorrectly, can cause significant damage to it. Contrary to what some may think, it’s best to prune during cold weather when the tree is dormant, not when trees are growing. The ideal time for pruning is between mid-November and mid-March. Trees pruned during winter months will have increased growth in the spring.
Keep in mind: Never trim trees that are close to overhead power lines, including the service connection to your home. That is a job for tree trimmers who are certified to work near power lines.
Start with removal of dead or damaged wood. In fact, branches damaged during storms should be removed as soon as possible. When splits in the tree’s wood emerge, they expand as the tree grows. This can result in fallen branches that bring down power lines and damage electrical equipment.
Always make a plan before pruning. Take into consideration the area surrounding the tree so that it will not come in contact with overhead power lines. If you’re using a chainsaw to prune, never reach above your shoulders. Ladders can be especially dangerous, so make sure that you have a firm foundation before you climb. Have someone stationed at the bottom for added stability.
Look up to make sure that you or your equipment does not make contact with an overhead power line as you prune. Start with the largest branches that need pruning before moving to the smaller ones. Trim at the growth points, not in the middle of branches.
While pruning, make sure that you take frequent breaks so that you can remain focused on the task. During these breaks, always look up to assess if pruning can be done safely in the surrounding area. Pruning your trees can be dangerous, so don’t hesitate to hire a professional to do the job.
