By late August the lawns around Centreville have gone two colors — straw where the sun sits all day, deep green under the old maples. Maz's Lawn Service reads that difference and cuts accordingly, leaving the blade a little higher in the heat so the roots keep something over them. Trimming follows along the walls and the chain-link; edging brings the driveway line back to sharp. Then September turns everything green again at once, and the cleanups begin. Whole stretches of West Warwick keep their footing this way, one yard at a time, week after week.
