Late August on the south end of town, the lawns have come through a dry spell and everyone is watching for the first cool night. Kozy Cares Lawn Service is on those streets the whole season — mowing, trimming, edging walks and drives, tidying up and carrying off what's cut. The compact yards on the south-side blocks reward attention more than horsepower, right down to the last inch behind the porch steps. Cutting a little higher through the hot weeks keeps the roots shaded and the color holding. When the rain comes back in September the grass turns deep green almost overnight, and the whole route looks like it's exhaling.
