The trees at Harold King Forest leaf out late, and until they do the light reaches all the way to the ground — a generous few weeks for the shaded lawns of Swampscott. Perez Brothers Landscaping and Tree Service mows and trims those yards where the canopy makes grass a negotiation, edging them clean so the shape stays sharp even where growth runs thin. Through summer the schedule simply holds, week after week, whatever the weather does. Spring and fall cleanups clear the debris the trees let go at both ends of the season. Steady hands, ordinary Tuesdays, and a yard that never gets away from anyone.
