I have a very large magnolia tree in my front yard. The roots are exposed and there is soil erosion. Can I place soil on the roots and/or plant ground cover around the tree to help eliminate the erosion? Thanks Chris Cheverly, Md.

Expert Response

It is common for magnolia to have surface roots. It will be difficult to plant around and among the root system of the tree roots. Also, the roots are always seeking moisture and there will be a lot of competition for moisture and nutrients.
At this point, it is recommended to mulch the area under the tree with no more than three inches of mulch. This will help keep weeds down, retain moisture, and prevent any lawn mower damage to the trunk. Keep the mulch away from the trunk.
