By late August the plains have gone the color of a paper sack and every lawn in Evans is negotiating with the water it is given. Sustainable Earth Care Services LLC mows for those terms — height left on the blade so the roots keep their shade, clippings handled with some thought, trimming and edging done without tearing at grass already under strain. Spring and fall cleanups lift the mat of leaves and dead growth off the crown so the turf can breathe again. Most of the craft out here is simply refusing to fight the country you are working in. Do that, and a high-plains yard will hold its green longer than anyone expects.
