North of Alpha the Musconetcong valley cuts down toward the Delaware, and in June the whole corridor is a wall of green with river light flickering through it. Dilts Landscaping LLC works the lawns of the borough in that season, mowing on a steady rotation, cutting edges tight to walks and drives, and trimming the corners a mower will never reach. Warren County soil over limestone can go from lush to thirsty in a fortnight, so the height of the cut matters as much as the frequency. Cleanups bookend the year — the winter debris raked out in spring, the leaves cleared once the maples let go in the fall. What stays with you is the look of a finished yard at dusk: even, clean-edged, and quiet.
