Some mornings in February, South Washington Avenue is plowed and salted before the first storefront light comes on, and nobody stops to wonder who did it — which is rather the point. Bergenfield Tree Service runs both halves of the year here: driveways plowed and walks shoveled through a storm, salt down on the ice that forms behind it, and then in April the mowers come out of the shed. The growing months mean weekly cutting, edging, string-trimming, hedge work and mulch in the beds. Autumn means leaves off the grass before they mat down for good. Winter arrives sideways off the ocean and leaves slush standing in every driveway apron — someone has to be up early, and careful about it.
