September along West Main is all oak shade and slow light, the Millikin blocks turning gold at the crowns while everything underneath stays green. Clark's Lawn and Landscape Services keeps the older Decatur streets where the trees are wide, the lots are deep, and the grass runs right up to a hundred-year-old curb. Mowing comes first, then the trimming and edging that make a big shaded lawn read as one clean shape, then the leaf work once the oaks finally let go in November. Shade lawns and sun lawns behave nothing alike here, and the cut height moves accordingly. Pulling away from a yard where the beds are tidy, the walk is swept and the edge is true — that is the point of the whole day.
