In Northwest Woods the oaks leaf out late, and until they do, May pours all the way down through the branches to the grass. Arbortech Tree & Lawn Care works that stretch of East Hampton where lawn gives way to pitch pine and sand, mowing, edging, and keeping trees and shrubs shaped so the light lands where a yard wants it. There is a real satisfaction in the last pass of the morning: the striping laid straight, the beds trimmed back to a firm line. Come autumn the same yards are raked open again, leaves lifted off the turf before the wet weather sets in. It is ordinary work, and it makes a place look loved.
