By the dog days of July, when the water at the south end of Boardman Lake goes flat and the walkers at Medalie Park stick to the shade, a lawn will tell on whoever cuts it. Scalped turf browns out in a week; turf cut high and cut sharp keeps its color right through the heat. Oasis Lawn Service works to the second kind, raising the deck when the weather turns dry and keeping the blades keen so the grass is sliced rather than torn. Trimming follows the fence line and the tree rings, and the walks get blown down to clean concrete before the trailer gate goes up. In the hottest stretch of a Garfield Charter Township summer, a green yard is a genuine relief — and that is exactly the point.
