Under most of Troy is heavy county clay, and clay packs down hard after a summer of foot traffic, mower wheels and August sun. Gordon's Lawn Core Aeration works against that with core aeration — pulling plugs so air, water and seed can reach the roots again — alongside the mowing and lawn upkeep that follows. Do it in the cool weeks of early fall and the turf answers by October, thicker and darker than the neighbors were expecting. There is something plainly satisfying about a lawn scattered with little soil cores after a pass, visible evidence that something real happened. By the time the next rain breaks them down, the ground underneath has already begun to open up.
