The Mystic slides past Rivergreen Park twice a day in each direction, and the strip of Everett along it grows greener every year somebody bothers with it. Lawn Care Landscaping & construction keeps that bother going on the yards behind those riverside streets — regular mowing, crisp edges along walks and drives, string trimming into the corners where fences meet. Spring cleanups pull off whatever the winter left behind; fall cleanups take the leaves before they mat down and smother the crown of the grass. Where a lawn might be twenty feet square, precision isn't fussiness, it's the entire point. The measure of a stop here is the edge: one clean line where grass meets concrete.
