A yard reads the way a drawing does — the borders decide it, and everything inside falls into place behind them. Four Sons Hardscape & Landscape Designs brings that eye to the lawn work in Ocean Acres: mowing in even passes, trimming so nothing shaggy is left at the corners, and edging until the curve of the walk is a line you could follow with your finger. On the wide corner lots out here, where the pines close in behind the fence, that definition is what separates a mowed lawn from a designed one. Late spring is the season for it, when the grass is thick enough to hold a crisp border all week. The work carries across Ocean Acres and the Stafford Township streets nearby.
