Stone walls run through the woods all over North Castle, older than the roads laid beside them, and in midsummer the lawns they border come on deep and fast after a thunderstorm. Ken Martin Landscaping Inc keeps that growth in hand — weekly mowing at a height suited to the heat, trimming around wall, post and trunk, edging beds and walkways so the shapes read clean from any angle. Hard surfaces get blown off before the truck pulls out. Cleanups take care of the ends of the season, when the ground is either waking up or shutting down. A lawn that looks effortless in August took somebody's careful morning, and that is the trade.
