The Satucket runs cold and quick through East Bridgewater, and the meadows beside it hold a green that seems to start a week ahead of everyone else's. Goulstons Fertilizer And More works the lawns of that river town — mowing on schedule, trimming tight to fences and foundations, edging so beds and turf keep their separate shapes. Spring begins with the cleanup: winter's litter raked out, the ground opened back up to light. Fall ends with the other one, leaves taken off before the wet weather sets in and mats the crown. It is a long, patient season here, and the reward is a lawn that carries the town's oldest color well.
