Morning in Indio arrives fast and white over the Coachella Valley, and by a July noon the desert light presses down like a hand on the shoulder. High Tech Irrigation brings lawn care and irrigation work to a city where every patch of green is a small bargain struck between sand and water. Past the date palms that the National Date Festival honors each February, the Little San Bernardino Mountains blush rose at dusk while sprinklers tick on across the cooling yards. Getting the water right is the heart of it here: soaking the roots, sparing the runoff, keeping turf soft to bare feet when the ground past the sidewalk is open desert. Come the mild winter afternoons, an Indio lawn kept this way is a green rest for sun-tired eyes.
