Late August, and the sunflowers along the fence lines stand taller than the mailbox while the shadows stretch halfway across the yard by seven in the evening. Tom Swagerty Plumbing mows Clayton lawns through that long-shadow stretch of the year, cutting even and holding the grass at a height that survives the afternoon. Edges are run along the drive and the walk; the trimmer takes the corners, the posts and the meter. Every clipping gets cleared so the finish actually holds. Nothing complicated about it — a yard that looks looked-after, week after week, right through the end of the season.
