In May the carillon at Stanley Park carries a long way on a still evening, and half the city seems to be outside deciding what to do about the grass. Herrins Landscaping LLC answers that question with a mower, a trimmer and a schedule: cut, edge, blow the clippings off the walk, come back next week. Mulch goes down in spring while the beds are still cool, and in November the leaf work runs until the yards are bare and tidy. Westfield turns green early and stays green late, which makes for a long season and a lot of Fridays that end with somebody's lawn looking exactly right. Small thing, but it changes how a house sits on its street.
