Rockmart got its name from slate — a rock market, quarried out of these hills — and the ground still shows it, gray ledges under thin red soil. Dumey Lawn Care LLC cuts on top of all that, late in the afternoon when the shadows of the pines start crossing the yards. Mowing, edging, trimming and yard cleanup, done on a steady rotation so a lawn never gets away from its owner. A hillside lot in Polk County takes some patience and some throttle, and the reward is a slope cut even from the road to the top of it. Nothing fancy — just a yard that looks right when the light goes gold.
