On a June evening in Pennington the ball fields at Kunkel Park fill with long shadows, and the smell of cut grass carries three streets over. Del Lawn & Landscape LLC makes a fair share of that smell — mowing yards across the borough and out into the township, edging the walks, trimming the fence lines and tree rings until a property reads as one whole piece. Spring cleanups pull the winter out of the beds; fall cleanups take the leaves off before they mat down and smother the turf. A lawn answers to attention faster than almost anything else people own, which is what makes the work worth doing well. Come back a week later and it has met you halfway.
