Why are my tree’s roots above ground?

Tree roots normally grow 12-18” below ground. Rain, runoff, and wind can erode the soil around the roots exposing them. If trees are crowded and don’t have enough space for its roots to spread, roots will move to the surface. Also, a lot of foot traffic around the root zone could pack down the soil so that it exposes the tree’s roots.

Exposed tree roots can be damaged by lawn equipment. Knicks and cuts to the root system can expose it to insects and disease. Damaged roots won’t be able to efficiently collect the water and nutrients needed to thrive.

What to do about exposed tree roots?

Don’t rebury them with more soil. Packed soil could hinder the feeder roots from getting needed oxygen.



A much better option would be to spread mulch over the exposed roots. The mulch will help cushion and insulate the roots and keep foot traffic and mowing equipment from the area.

Suggested mulch to use is organic such as wood chips or shredded wood. Spread the mulch evenly, 3 to 4 inches deep. Be sure to spread it to cover the area of exposed roots including the lawn, if needed. Mulch surrounding the tree makes for a healthier environment than grass.

Be sure to keep mulch away from the trunk’s bark. Piled mulch against tree bark can lead to rot or disease. Be sure to spread the mulch evenly and watch for mulch decay and thinning. If you see the mulch thinning, spread more and make sure it isn’t more than 3” to 4” deep.
