August in Robbinsville Township lays a shimmer over the wide lawns that took the place of tomato and corn ground, and the grass tells you right away how the week has gone. Green Lawn Irrigation, Inc. mows and maintains those properties — weekly cutting at summer height, edges run clean along drives and walks, trimming at the posts, and cleanups when the season flips. Mercer County's old farm soil grows a big lawn well, which also means a big lawn to keep up with. There is real pride in a broad open yard cut straight, the lines running the full length without a wobble. Late summer evenings out here are long, and the finished lawns hold the last of the light.
