June mornings at Devir Park start with sprinklers and end with a ball game, and the streets around it fill with the sound of mowers. Moise's lawn care is one of them, cutting on a weekly rhythm, edging drives and walkways, trimming close to fences, posts, and the small front-yard trees. Grass in Malden runs hard in early summer, and a lawn that skips a week takes three to look right again. Cleanups bracket the season, opening the yard in spring and clearing it out in the fall. A short, even lawn on a hot day is one of the plainest pleasures a city block has to offer.
