By late July the Inland Empire heat sets in for weeks at a stretch, and the only sane hour to cut grass in Montclair is the first one after sunrise, while the shade still reaches across the driveway. RMS Landscape Services starts there — mowing high enough that the turf shades its own roots, edging and trimming crisp, feeding and treating weeds on a schedule that respects how much a lawn can take in triple digits. Push a lawn wrong in a Montclair summer and you will see the answer in a week; treat it right and it holds green all the way through. The trucks are loaded before the heat arrives and rolling before most of the street is awake. That early start is half the craft.
