In the Gila Valley water arrives on a schedule, running the ditches to the fields and the yards each in its turn, and everything green in town owes something to that timing. The Drip Doctor, LLC keeps Pima lawns in shape between those turns — mowing at a height that suits the heat, edging the walks, trimming the borders, and lifting the clippings so nothing sits and scorches. Midsummer the middle of the day belongs to nobody, so the work happens early, while the air is still soft and swallows are out over the ditch banks. A lawn cut with attention in July stands up far better through August; that is most of the trade right there. And a yard that looks even and cool from the porch repays every drop it took.
