By six on a June morning the grass out toward the Segreganset holds so much dew that a single pass turns a whole lawn two shades darker. Sustainable Lawncare works that early window, when the air is still cool off the low ground and the cut sits kindest on the blade. Mowing on a steady rhythm, trimming close along fence lines, edging where turf meets walk — the ordinary upkeep that carries a Taunton yard from the first April flush to the last stubborn growth of October. The Silver City has no shortage of old lots with thin corners and long shade, and coaxing those back to an even green is an argument you win a week at a time. Taunton is home ground, with Raynham, Berkley, Dighton and Norton close behind.
