Down at Branchville the land drops toward the Norwalk River, and the light in that valley is the same light painters came out from the city to work in at Weir Farm a century ago. Moore Lawn Maintenance LLC. mows there and up the hill behind it — weekly cuts, trimmed edges, clean lines around beds and walks, seed and fertilizer to keep the green honest. A lawn catches evening sun better than almost anything else in a yard, and a good cut is what makes that visible. Spring and fall cleanups bracket the season on either end. Ridgefield and the towns around it are their working map.
