Midday in Nockamixon: sun straight overhead, Tohickon Creek loud in the rocks below, and the lawns of the river hills tilted toward the water. D&K Property Maintenance mows those slopes and the flat stretches alike, keeping the turf even where the ground never is. The trimmer runs along stone walls and old post fences, then the drives are cleared so nothing gets tracked back into the house. Growth is heavy in a wet Bucks County June, so service comes weekly and the cut stays healthy instead of scalped. The finish is what carries — a lawn lying smooth against the hillside, with edges you notice without knowing why.
