The bike path through Amherst follows an old rail bed, straight as a drawn line, and every April the green comes up along it in about a week. Naccarato Landscaping & Design, LLC likes a line like that — mowing in parallel passes, edging walks and drives to a firm border, trimming the corners a mower cannot reach, mulch set to hold the shape of a bed. Cleanups open the spring and close the fall. When the weather turns, the same equipment plows the drives, clears the walks and puts salt where ice keeps coming back. Design is only the summer word for what the plow does in January: making ground usable again.
