By mid-July the corn stands tall along the section roads east of Coldwater and the heat sits on Branch County like a flat hand. Lawns in town go pale at the edges first, along the sidewalk and on the south side of the garage, and that is where mowing height and timing start to matter more than anything else. B & D Irrigation works the turf side of that summer: cutting on a rhythm the grass can carry, trimming close around posts and fence lines, keeping the border honest where lawn meets drive. Early mornings are the best of it, dew still silver, the first pass laying a dark stripe across a yard nobody has walked on yet. By evening the whole street looks like someone is paying attention, because someone is.
