A bed edged clean along a Powow Hill driveway holds its line all summer — dark mulch, a blade's-width of shadow, grass stopping exactly where it was told to stop. That is the kind of result Green World is after in Amesbury, whether the day calls for mowing and edging, fertilization and aeration, a patio or retaining wall set level into the slope, an irrigation line laid and later drained for the cold, or plow work that opens a driveway while the mill windows down by the Powwow River are still dark. There is real pleasure in it: shrubs planted where they will look intentional in ten years, tick protection walked across a yard that borders the woods, a fall cleanup that leaves the lawn breathing again after the maples let go over Lake Gardner. Landscape lighting comes on at dusk, a small pond moves water in the corner of a yard, and the whole place looks like someone loves it — because someone does. From Amesbury out across northern Massachusetts and southern New Hampshire, the work is simple to describe and satisfying to stand in front of.
