Before the parking lots fill along Manchester Expressway, the mowers are already making a first pass over the wide turf that fronts Columbus's business corridors. Mainscape keeps grounds like these on a maintenance rhythm of mowing, edging, string trimming and blow-off, repeated until a property reads uniform from every approach. Large lawns are unforgiving, and a missed strip shows from the road at forty miles an hour. So the lines run straight and the borders stay tight. By opening time the place looks looked-after.
