Hawthorne Brook keeps its corner of Townsend shaded and cool, and lawns in that kind of light want a lighter hand. Sato Solution Tree Services mows, trims and edges yards across town, with a clearing-out in spring and a full leaf cleanup come fall. On a late-summer afternoon the shade moves slowly across a fresh-cut lawn and the whole yard looks settled. Growth slows in September but the schedule does not, right up to the last mow of the year. The work is plain and the result speaks for it: a yard that looks cared for from the road.
