Planes lift out of Newark and cross Roselle in a slow procession all evening, and underneath them the borough's lawns cool off and let go of the day's heat. M&T Landscaping LLC works those hours and the ones before, mowing, trimming, edging and clearing yards through the borough's flat, close-set streets. A good share of the craft is in the finish: blown-clean walks, a level hedge line, nothing left in the gutter. Spring here is fast and generous, so weekly cutting is less a chore than a way of keeping up with the ground. By the time the light goes orange over the rooftops, the whole block reads as tended, which is the entire point.
