Above the Norwichtown Green the land tips down toward the harbor, and late in the day the light comes off the Thames long and gold. V&M Luxe Landscaping LLC keeps Norwich lawns on a rhythm through the growing months — mowing, trimming, edging, and the cleanup that follows a windy night. It is simple work done attentively: a straight line held along the walk, a clean sweep where clippings would otherwise drift, grass kept at an even height week after week. The hills here are steep and the lots are small and awkward, which is exactly the kind of ground that rewards someone who keeps coming back. Street by street, the reward is a row of houses that all look looked-after.
