By the middle of July the fields north toward Olathe stand shoulder-high, the whole valley smells green, and lawns in town are growing like they are trying to keep up. Delta Company Lawn Care runs mowing and trimming through that stretch, when a week between visits is a week too long. High-desert grass is a made thing here — it lives on irrigation and attention — so the cut is set to leave enough blade for the grass to shade its own roots. Edges get cut in along the walk, clippings get cleared off the concrete, and the yard is handed back looking like somebody loves it. In September, when the heat finally lets go, the cleanups begin and the season closes out neat.
