Root pruning service is another area where the stump grinder is a common means to mitigate migrating root issues on healthy trees. The stump grinder does an effective job, especially on larger roots which can be cut and buried as long as the teeth on the machine are sharp and the cut isn't too close to the tree.

Smaller roots from smaller plants can also be pruned with a stump grinder but will need added attention. Smaller roots will get somewhat mangled in the process of the grinding and will need to be cleaned up by hand to help the plant better seal up the root where the cut was made.
