On a July evening the long straight blocks between the river and the rail line go quiet, sprinklers ticking, the heat finally letting go. Treasure Lawns Inc spends those months keeping ordinary Rahway yards in good order, mowing on a dependable rotation, trimming fence lines and foundations, edging the walk so it stands out against the turf. The city's older shade trees make for patchy light, and grass there asks for patience: cut at the right height, kept clear of leaf litter, given mulch where the beds run dry. Spring cleanup gets the season underway and the autumn pass carries it out. What is left, week after week, is simply a lawn in good hands.
