By July the bluff country holds its heat, and the coolest thing for a mile is the shade in a ravine where the walnuts lean together. DC Tree and Landscaping Services works those long midday hours through Medina Township with mowing, string trimming, bed edging, mulch and the cleanups that keep a yard from swallowing itself. On a hillside lot the mower runs across the slope and the trimmer finishes the rest, right up to the posts, the mailbox and the base of every tree. What is left behind is simple and legible: even grass, sharp lines, nothing shaggy at the corners. Then the truck rolls back down toward Route 29 with the windows open and the day cooling off.
