In April the alewives push up Stony Brook and the marsh grass along Cape Cod Bay goes a raw, hopeful green — the week Brewster yards wake up and ask to be tended. Estates Landscape-Maintenance Tree Service works those sandy lots and Route 6A dooryards under their old oaks: mowing and lawn care through the long bright summer, landscape maintenance that keeps a bed reading crisp against the pitch pine, tree work when a limb leans too far over a drive. Come winter, when a nor'easter blows in off the water and lays wet snow across the flats-side lanes, the plowing starts before the light, opening driveways back down to pavement. It is plain, physical satisfaction: an edge held clean, a path made passable, a Cape yard that looks cared for all the way from the road.
