Understanding the importance of tree root care
The majority of a tree's roots are found in the top 12 inches of soil, with the fine roots that absorb water and nutrients located in the top 3 to 5 inches. Because these critical roots are so shallow, they're vulnerable to disturbance from everyday landscape activity and construction work.
Common causes of tree root problems
Trees may suffer from excessive or insufficient water, poor drainage, extreme soil pH, improper planting depth, de-icing salt damage, herbicides, and construction disruption. When roots are neglected, a variety of problems can develop, including root rot, stunted growth, and even tree death.
Warning signs to watch for
Several visible signs can indicate a root problem: lack of a visible root flare at the base of the tree, fungal growths on roots or the trunk, yellow, light green, or undersized foliage, unusually large crops of berries, cones, or acorns, and stunted twig growth.
