Stump grinding is one of the many tree removal services offered by the Georgia Tree Company. Stump grinding is the process of grinding a stump that's been left after a tree is cut, and most stumps are cut into small pieces so there's nothing left except a few inches of stump resting below the earth. The remaining part of the stump is covered with soil and dirt, and then it's up to mother nature to take care of the rest; the ground stump could also be used as mulch.
