Rockland's North End is full of granite — walls, steps, foundations — and the lawns around them have to be cut to fit. Mid Coast Landscape and Masonry keeps those yards through the season with cutting, trimming, close edge work and the cleanups that open and close the summer. Grass on this coast grows in a cool green way, slow and dense, and it holds a line beautifully once it has been cut. The satisfaction is in the detail: a border trimmed tight against old stone, a lawn even from the sidewalk to the back fence. In July, with the harbor light coming up the street, that is a fine thing to leave behind you.
