A lawn in Darien looks best in the hour after the mower leaves — stripes laid straight down the slope, the edge along the walk cut clean enough to read like a pencil line. That is the work Red Carpet Landscaping keeps at: mowing, trimming, edging, and the seasonal cleanups that carry a yard from first thaw to last leaf. The ground here runs from the tidal shine of the Sound up through oak shade and old stone wall, sandier near the water and heavier inland, so the grass asks for something a little different block by block. They tend lawns across Darien and the neighboring Fairfield County towns, learning each property by the shape of its shade. There is a plain satisfaction in a yard that holds its season, and in the moment someone steps out the door and finds it waiting.
