By the middle of July the Rouge runs low and slow behind Ford Field, and the grass on either side of it grows like it has somewhere to be. Busch Lawn Care LLC keeps that pace with weekly mowing, trimming along fence lines and beds, and the edging that gives a yard its outline. Cleanups bookend the year — the wet matted mess of April, the deep maple drop of November. A mown lawn in the long evening light of a Michigan summer is a plain thing and a good one, and it is worth doing on schedule rather than when it gets loud. Work runs across Northville and south toward Plymouth and Canton.
