July over the bridge into South River, and the heat lifts off the water and the asphalt at the same time. Tigermaster landscaping services LLC unloads at the curb, walks the gate, and gets into the borough's lawns before the day turns mean. Mowing on a schedule that keeps up with a humid week, string trimming to the fence and the foundation, edging the walk, then clearing the cuttings so nothing is left to yellow on concrete. Humidity off the river pushes growth hard, and holding a lawn to its rhythm through August is the difference between cutting grass and mowing hay. By afternoon the lawn is short, edged sharp and cool looking, and the truck rolls on to the next street.
