Mount Graham stands over Thatcher like a weather report, holding snow into spring while the Gila Valley below has already gone green with alfalfa and new leaf. Valley Edge Yard Care mows and trims across that valley floor, where irrigation water and long sun grow grass the way almost nowhere else in this corner of Arizona does. The job is the ordinary week done properly: cut at the right height, edge the sidewalk, trim the fenceline, sweep the concrete clear of clippings. Summer afternoons here push past a hundred, so the mowers roll early and the yards are finished before the heat sets in. Between Thatcher, Safford and Pima, a square-edged lawn is a small and very visible pride.
