West of Edmond the blackjack and post oak of the Cross Timbers close in, and red dirt shows through wherever the grass gives up. Lawngevity mows the yards on the Deer Creek side of town, where wind crosses open ground and pushes cut grass sideways all afternoon. The trimmer runs around the oaks and the culvert stones; the edger cuts a firm line where lawn meets red gravel. A yard out there looks right when the turf is even and the border is honest. Lawn maintenance for Edmond and the section roads running west.
