The North Branch of the Raritan runs cold and shallow through Far Hills, and the lawns above it stay green well into a dry August. Todd's Lawn Care keeps them that way — weekly mowing, trimming close to posts and plantings, borders cut where turf meets stone and drive. Late afternoon is the good hour for it, once the heat lets go and the hedgerow shadows stretch across a finished lawn. A blade kept sharp cuts grass instead of tearing it, and by the third week the difference is visible from the road. When the leaves come, the cleanups run right through to the cold.
