Pine Banks Park stands on Malden's northern edge, all ballfield and pine, where the city hands itself off to Melrose. Lawn and Fields of Boston LLC mows and maintains the yards down along that boundary — regular cutting, trimming out the corners, edging the drive lines, and clearing the ground when the season turns over. Pine needles and oak leaves come down together here, and a lawn left under them will go yellow inside a week if nobody moves. So the ground gets cleared, the cut stays even, and the border stays where it was drawn. It is a plain promise kept: come back on the day, cut it right, leave nothing behind.
