Question:

I’m noticing that my tree’s roots are growing at the surface of my lawn. What should I do?

Answer:

Some tree species are more prone to doing this, but it can happen with almost any tree. It’s important to remember that the majority of the tree roots are within the top 8” of soil. As the tree grows, roots can be more visible at the surface as they get bigger, or if there is erosion of the surface soil, or if the soil is compacted and doesn’t drain well.

Do NOT prune these roots as that can cause serious damage to your tree. Instead, you can apply a shallow, 1 – 2 inch layer of good-quality soil mix and then replant the grass. However, it won’t be long before tree roots will reappear again. Even better, replant the affected surface area with a taller ground-cover type plant and other flowering plants that will not need mowing, being careful to avoid injury to the major tree roots at planting.
