On a June morning the water at Lake Mohawk throws light up under the trees, and the lawns running down toward it are green in the way that only cold nights and lake air can manage. Burns Lawn & Landscape LLC mows and trims those Sparta properties, the sloped ones, the rocky ones, the yards that end at a stone wall or a hemlock line. Highlands soil is thin and full of glacial rock, so grass up here is earned rather than assumed, and it answers to steady care. Mowing, trimming, edging and seasonal cleanups keep it answering, from the first cut after mud season to the last before the ground hardens. A hillside lawn cut clean with the lake glinting past it is worth walking back to the truck slowly to look at.
