How to Trim Tree Branches Over House

Trimming trees and bushes around your house is a crucial aspect of landscape maintenance. If planted too close to the house or not kept in check, shrubs and trees can quickly take over a space and will eventually become too big to prune or control. Here are some whys and how-tos for trimming shrubs and trees away from your house.

Trees especially are notorious for damaging houses if planted too close. Tree roots tend to grow to at least the size of the canopy, if not bigger. This is great for keeping your trees sturdy and healthy but can cause problems if roots start growing into the foundation of your home, which will ultimately damage it. Keep large shrubs and trees at least 10-30 feet away from the foundation of your house. If that’s not possible, then practice good pruning to minimize root growth. There is also the obvious problem you want to avoid: limbs or large branches can break off and damage your house if the trees are too close. Good pruning practice can ensure that heavy limbs aren't at risk of falling onto your home.

Finally, branches and leaves that touch the siding of your house will leave the home susceptible to water damage, pets, rot, mold, and mildew. If you have trees or shrubs that touch your house, be sure to keep them pruned 6-36 inches away from the siding so that nothing is actually touching your house.

You will want to begin with the right tools. Depending on the size of the job, you will want a pair of gardening shears, hedge-cutters, wood-clippers, or even a power trimmer. It is imperative to make sure that your tool of choice is clean to prevent the spread of disease. Wipe down the blades with bleach or vinegar to sterilize before using. Be sure to clean again between plants.

Regular trimming helps maintain the health of your plants by removing dead or diseased branches, promoting healthy growth, and preventing overcrowding. By following proper trimming techniques, you can keep your yard looking clean.

Step 1: Access the Situation

Begin by assessing the situation to identify which branches are too close to the house. Look for branches that are touching the structure, overhanging the roof, or too close to windows.

Step 2: Plan the Cuts

Determine where to make your cuts to encourage healthy regrowth and maintain the tree’s natural shape. Start by making a preliminary cut a few inches away from the final cut location to prevent the bark from tearing.

Step 3: Make the Cuts

To trim a branch properly, first make a notch cut on the underside about a foot from the trunk, cutting one-third through to prevent bark stripping. Next, make a top cut a few inches further out to remove the branch and relieve weight. Finally, make a clean, smooth cut just outside the branch collar to promote healing.

Step 4: Post-Trimming 

After trimming, clear away the cut branches and dispose of them. Sterilize your tools with a disinfectant like bleach or rubbing alcohol, especially if you trimmed diseased branches. Post-pruning, check the tree for signs of stress or disease, water if needed, and apply mulch around the base to help retain moisture.

How to Trim Bushes in Front of Your House

While trimming trees over your house and trimming bushes in front of your house involve different techniques, they accomplish the same goals. One of the main differences between the two is that bushes are generally more accessible, making them easier to trim with basic hand tools like shears, pruners, and hedge trimmers. Trimming trees over your house requires more safety precautions, specialized equipment, and strategic cuts to protect both the tree and your home, while trimming bushes in front of your house is more about maintaining curb-appeal and plant health.
