Parts of Berkeley Heights are more woods than lawn — Free Acres and the lanes around it keep their oaks close, and the grass underneath has to be coaxed. Santamaria Landscaping Inc mows those shaded yards with care for what they are, edging along drives, trimming around trunks and stone, keeping turf even where light comes through in patches. July afternoons up on the ridge stay cooler than the valley, and the smell of cut grass under big trees is one of the better things about the work. Spring and fall cleanups clear the leaf load these lots produce in earnest. The finished yard is a small, tidy clearing in a green town.
