Summer air off New Haven Harbor comes in soft and salty and makes the grass along Long Wharf grow like it is being paid to. Turf Angels keeps ahead of it across the city — mowing on a weekly turn, string trimming, edging, and clearing every clipping off the walk before leaving. Feeding and weed control keep the turf even where the sun bakes the south-facing yards all afternoon. Autumn brings the leaves and the last low cuts, and by four o'clock the harbor light has gone silver. Lawn care in New Haven and the towns around the harbor.
