By noon in midsummer the air along Manalapan Brook goes thick and still, and the lawns above it live on whatever the night left behind. Clipper Lawn Maintenance runs a route through those Spotswood streets and out toward Helmetta and Jamesburg, cutting on a rhythm the grass can hold in heat. The deck goes up when August bites, so the roots stay shaded and the color stays put. Trimming follows fence lines and mailbox posts, and a firm shoulder of edge gets kept along the curb. Cleanups bookend the year at either end. What all of it is for is simple: a yard that still looks cared for on the hottest week of the season.
