Under every lawn in Roswell there is red clay, and anyone who has put a shovel into it in August knows it gives nothing away for free. Grass Roots Landscaping takes the name at its word — the good-looking part starts below, with turf held at the right height, edges kept to their line, and clippings handled so they feed the ground instead of smothering it. Out along Hardscrabble and Cox Road the hickories and sweetgums drop hard in November, and clearing leaves becomes the entire afternoon. The reward arrives months later, in a yard that comes out of winter thick rather than thin. They keep lawns across Roswell, Milton, Woodstock and Mountain Park.
