A chipper humming on a back road off Amity, a chain slowing to nothing, a stump ground flat and the sawdust raked away — Capasso Landscaping & Tree Removal works in that steady sequence of engine and hand, and Bethany's wooded ridges give it plenty to answer for. Up on this traprock hill town above the New Haven basin, where stone walls run off into the oaks and driveways bend long through the trees, the work runs to mowing, aeration and overseeding, landscape design and installation for homes and businesses, hardscape set into the slope, excavation and drainage cut where the ground wants to hold water, and trees taken down when a storm has finished with them. Winter makes the same roads a different problem, and the plows go out ahead of the light so a snow-club driveway or a commercial lot is open before anyone needs it. What stays behind is the plain pleasure of the thing — an edge you could draw a line by, a yard that sheds its rain, a stretch of Bethany, Naugatuck, Prospect and Seymour that looks like someone tended it.
