On a hazy July morning off Old Town House Road you can smell the Sound long before you see any of it, and the lawns hold their dew until nearly nine. NewGrass Landscaping LLC uses that window — mowing, edging, trimming, weeding and mulching early, with overseeding and feeding worked in to thicken the sandy spots that thin out every summer. Cleanups bracket the year and haul off whatever the wind and the oaks leave behind. When the season flips, the same trucks go out with plows: driveways and walks cleared, sand down on the ice at the step. New grass in May, clean pavement in January — that is the whole year in this town.
