Pomona sits in the lap of the Ramapos, where Rockland's ridgelines come down into orchard country and the mountain shadow reaches the yards early in the evening. Christopher Meredith Landscaping mows in that shadow and in the long morning light before it — cutting, trimming, edging along walks and drives, and cleanups when spring opens and again when the oaks let go all at once in November. The ground here is rocky and rolling, so a lawn is something you earn rather than something you inherit. All the more reason to leave it striped even and edged clean. Under those hills, a well-kept yard looks exactly right.
