Tree pruning steps now can prevent storm damage later

Last June’s destructive storm showed that trees can be the victim of heavy wind storms. After that historic storm, lots of homeowners were trimming downed branches, clearing trees off rooflines and even making plans to remove large uprooted trees that fell victim to winds estimated at 80 to 100 mph. But, there’s steps you can take to prevent some of this type of tree damage next time.

This damage is often caused by defects in a tree. One way to minimize these defects is to perform preventative pruning in the first 10 to 15 years of a tree’s life.

According to OPPD foresters, pruning promotes good structure and makes the tree more resistant to storms. This preventative pruning directs the growth of the tree by cutting branches that aren’t growing correctly.

Below are some common defects to look for. Correcting these defects now will help your trees withstand severe weather. More tree planting tips can be found at

Codominant stems with a “V” shape at the joint often have included bark, which is bark pinched between two stems, creating a weak union. Prune to eliminate this defect by leaving the stem that will give the tree a dominant leader.

LARGE LOWER LIMBS: Low branches on large shade trees are temporary and should be removed early in a tree’s life. The lowest permanent branch on many shade trees should be 12 to 15 feet off the ground. Prune these branches early in the tree’s life to prevent larger pruning wounds in the future. If you remove these large limbs later in the tree’s life, it weakens the tree and makes it prone to storm damage.

If a cut is made correctly, the branch collar of the tree (the bulge where the limbs join) should be intact. A proper cut will leave a round wound with the callus tissue forming a “donut” shape.

  1. Wow! You couldn't be more correct! Our company often gets called out for emergency tree services after a big storm has blown through the area and left tons of debris and downed trees. One of the things that we tell home and business owners is to make sure they try to do their preventative work in order to avoid having so much tree debris. Tree pruning, while very important, is often overlooked. If done correctly and on a regular basis, it can really solve a number of problems. We've taken pictures and posted some of what we're talking about here:
    Thanks for helping to spread the message! Best of luck!

  2. Rose of Sharons are best pruned when dormant because the blooms will grow on new wood. It’s also one of the last trees to get its leaves in the spring, so every year I think I’ve killed mine, but they always come back (despite following an incorrect pruning schedule). However, this past spring, part of one of the trees didn’t come back, so when I consulted my manual, I discovered that we shouldn’t be pruning in fall and may have inadvertently killed the tree.

  3. It’s good that you point out that pruning is great for the health of your trees. I want the trees in my yard to be healthy, so I’m considering hiring a professional to prune them. I’m going to look for a good provider of tree pruning services in my area to hire.

  5. I thought it was very interesting how the article said that pruning promotes good structure and makes the tree more resistant to storms. My father has a ton of trees in his backyard that he has trouble keeping properly trimmed and healthy, so he has been thinking about hiring a company to go to his home and help him take care of them. It would be beneficial for him to have the help of professionals to ensure that his trees are healthy enough to survive any storms that may hit his area.

  6. It’s valuable that you point out that having your trees pruned can help make them more structurally sound as they grow. I want the trees in my yard to be strong and healthy, so I’m considering hiring a professional to prune them for me. I’m going to search for a good business in my area that offers tree pruning services to hire.

  7. Great post! Keeping an eye on your trees and attending to potential problems can really save you a giant headache down the road!
