Not only will it bring insects, but the slimy, black mess oozing ...
Stump Grinding in Orlando, FL
Stump grinding is a method used to quickly remove tree stumps from the ground. Using advanced equipment with fixed carbide teeth and a highspeed cutting wheel, the grinding process removes stumps and tree roots by cutting them into small chips, similar to mulch. The mulch can then be collected and removed from the property.

What To Do About Exposed Tree Roots
Tree roots are not motile. Some trees, like maple, have extremely shallow roots. If a tree root is exposed to the air, it's generally because the soil left. And why did the soil erode from around the tree root? Well, typically, it's because there was nothing holding it there. We're all familiar with the problem of grass dying under trees.
