Evening settles over East Taunton, the sun drops behind the Segreganset, and the last pass of the mower lays long stripes across the yard. Superior Lawn Care runs the ordinary rhythm of a growing season here — cut, trim, edge, blow the walks clean, come back in a week. The year opens with cleanups and whatever winter left behind in the shrub beds, and closes with leaves, which the old street maples make a full project out of. A lawn is one of the few things a person can finish completely in an afternoon. That is the appeal of it. Doing it again seven days later is the trade.
