On a January morning the loop road around the mountain runs silver with frost, and every lawn in sight is the color of a paper bag. Green Mountain Lawn Care keeps working anyway — dormant-season cleanups, leaves and fallen limbs cleared, edges kept honest so that when March warms up there is nothing to undo. Dormancy is not neglect; it is a yard held in place until it is ready to go again. Come the first true cut, you can tell from the street which lawns were tended through the cold and which were left alone. Service covers Stone Mountain and out toward Tucker, Clarkston, Redan and Snellville.
