The Nishisakawick Creek slides quietly through Frenchtown on its way to the Delaware, and by July the whole borough smells of warm stone and cut grass. Copper Creek Landscape Management works the long middle of the growing year here, mowing, trimming, edging beds, and handling the cleanups that open spring and close out fall. Out where the old rail line runs north toward Milford the properties widen into Hunterdon hillside, and a lawn out there takes patience and a straight eye. Done right, the stripes hold their shape until evening, when the light comes sideways off the ridge and shows every one of them. That is the part worth doing well: a place that looks tended, not just mowed.
