West of the Norwalk River the land goes quiet and rolling — old fieldstone walls, and the meadow grass at Cranbury Park leaning gold through a late-August afternoon. A Cut Above Landscaping keeps lawns in this part of town, mowing and tending turf so a yard reads as cared-for from the curb. The reward is plain and visible: a clean line where grass meets bed, stripes running true across a slope, color holding into the long light of evening. Norwalk summers come up humid off the water and its Septembers arrive suddenly cool, and a lawn here has to answer to both. It is steady, repeating work for homes around Norwalk and the towns beside it.
