Will Cutting Tree Roots Kill The Tree?

Reaching far and wide, roots are vital to creating a tree’s foundation. If the tree roots grow too far for your liking, though, you may want to remove them. Yes, you can cut roots without killing a tree, but it’s crucial to follow the specifications outlined below.

If You Cut Roots, Will It Kill The Tree?

Killing the tree by simply cutting a few roots will all depend on the size and location of the roots. It’s suggested to always avoid pruning roots that are more than two inches wide. The removal of larger tree roots can make the tree unstable and/or unhealthy.

If larger tree roots are ultimately removed, the tree may not be able to get enough water and nutrients. Additionally, make sure not to remove roots close or fused to the trunk because these are crucial to the overall structure of the tree.

How Can You Cut Roots Without Killing The Tree?

As mentioned, if you end up cutting tree roots, there is no guarantee that it won’t hurt or eventually kill the tree. It’s only suggested to remove roots when they are either damaging or infringing on surrounding structures. Refrain from cutting roots simply for aesthetic purposes.

Never remove more than 15 percent of above-ground roots at one time. Try to wait another two to three years before making any additional cuts, as this will give the tree the chance to fully recover. Contact your local arborist before attempting this task to ensure the best chance of your tree surviving.

When Is The Best Time To Cut Tree Roots?

Cutting roots during the winter or early spring is suggested. These are seen as the best times of the year to remove roots. However, there are a few meticulous steps you must take to cut the roots properly.

How To Cut Tree Roots

Use this step-by-step guide to complete this DIY task safely and efficiently.

Step 1.

• Locate the root posing an issue and begin by measuring its diameter.
• If the root is less than 2″ and does not add up to more than 15 percent of the surface roots, it is safe to remove.

Step 2.

• Measure the diameter of the tree with a measuring tape.
• Wrap the tape around the tree, four feet from the base of the tree.
• Divide that number by 3.14, then you can safely prune roots that are 5 times the diameter away from the tree.
• If your tree only has a diameter of three feet, only cut roots 15 feet away from the tree.

Step 3.

• Mark the area that you are about to cut.
• Dig a hole all the way around the root until it is exposed completely.

Step 4.

• Cut the root cleanly with a pruning saw.
• Carefully pull the cut root up and away from the tree until it is completely removed.
• Refill the new hole that’s been created with soil from the same area.

Step 5.

• Keep a close eye on your tree after the pruning process for a few weeks.
• Call an arborist immediately if you notice any signs of decline, such as yellowing leaves.
