Removing Girdling Roots: A Key to Tree Health and Longevity in North Street, MI

Girdling roots are tree roots which encircle or press against a tree’s trunk, essentially strangling the tree. These roots can significantly harm a tree's health by restricting the flow of water and nutrients. If left untreated, they can lead to poor growth, stress, and even tree death. Proper removal of girdling roots is essential to ensure the long-term health and stability of your trees.

Identifying Girdling Roots

Consult one of our ISA Certified Arborists at Owen Tree Service to help identify girdling roots. These roots are often found near the base of the trunk, where the root flare should be visible. The root flare should swell out at ground level vs. looking like a telephone pole.

Trees planted too deeply or mulched excessively are more prone to developing girdling roots. Symptoms include a lack of visible root flare, stunted growth, trunk swelling, and dieback in the canopy, typically on the same side of the girdling root.

Steps for Safe Removal of Girdling Roots

1. Expose the Root System: Utilizing tools like an AirSpade to carefully remove soil around the base of the tree and expose the girdling roots without damaging other parts of the root system. An AirSpade is a soil excavation tool powered by a large air compressor that safely removes the soil around the base of the tree without causing any harm to the plant.
2. Assess Root Size: Roots 2 inches in diameter and smaller can usually be safely removed using hand pruners or saws.
3. Make Clean Cuts: Use sharp tools to cut the root cleanly at a point 6-12 inches from the trunk. Avoid pulling out deeply embedded roots to prevent damage to the cambium layer of the tree.
4. Monitor Tree Health: After removal, ensure proper mulching, which is no more than 4’ of mulch; and keep mulch away from the tree trunk. Proper watering and fertilizing should also follow girdling root removal.

By addressing girdling roots when the tree is young, you can improve your tree’s health and longevity while adding value to your property.
