Putnam Valley is built on granite — ledge breaking through the hillsides, glacial boulders parked in the middle of otherwise ordinary yards — and the lawns here are fitted around the stone rather than laid over it. Ionic Lawns mows those shapes at high noon in July, when the rock throws heat and the grass along the ledge needs a lighter touch than the flat by the road. Trimming works the seams where turf meets stone; edging keeps the beds reading as deliberate lines instead of drifting margins. Spring and fall, the whole property gets cleared down to clean ground. A lawn that respects the rock it grows on looks better than one that pretends the rock isn't there.
