By late September the maples around Kennedy Park have started turning at the tips, and the grass — rested from August — comes back thick and deep green. Costa's Landscaping LLC works Sayreville lawns through that best stretch of the year and every stretch besides: weekly mowing, string trimming around posts and beds, a clean line cut where the turf meets the driveway. Fall cleanups follow, taking the season off the lawn before it mats down and smothers what is underneath. Come spring the same yards wake up open and breathing, ready for a first cut. A lawn kept on schedule tells on itself — you can read it from the street.
