Noon in Colonial Heights. Retaining walls, terraced yards, hedges holding a slope in place. GreenEdge Solutions mows and trims these properties, edges the walks, and keeps hedges and beds in shape right through the growing months. A terraced lawn is really three lawns, each wanting its own pass, and the wall lines have to be trimmed by hand. From the street the result reads as one clean plane of green — which is exactly the illusion worth the extra half hour.
