April here arrives in pieces: one warm week, one cold one, then the whole hillside greens at once and the mowers start. Three Shades of Green LLC opens the season in Rainbow Lakes by raking off what winter left — grit, twigs, the last flattened leaves — and giving the turf its first cut of the year. From there it is a rhythm: weekly mowing, trimmed edges along drives and walks, and cleanups again when the highlands cool. Denville's lake neighborhoods have short lawns and long memories of hard winters, and turf that comes back thick in spring feels like proof of something. It is plain work, and it makes a street look like itself again.
