Follow the Saddle River south out of Ramsey and the green never really breaks — backyards, hedgerows and a ribbon of shade running town to town. Greenbelt Landscapes Inc works inside that ribbon, and in midsummer, with the cicadas going flat out at noon, that means keeping turf at a height that holds moisture and color through a dry week. Mowing, edging, fertilization and weed control, aeration, mulch, hedge and shrub shaping, spring and fall cleanups — a full circuit of the year on one property. The reward is a lawn that stays deep and cool underfoot in the middle of August, when the heat is doing its best to argue otherwise. Ramsey, Saddle River, Upper Saddle River, Allendale and Ridgewood: one long green belt, kept.
