Late May, and the old oaks off Passaic Street throw so much shade that a lawn has to be coaxed rather than commanded. Kennedy Landscape & Design mows and trims those shaded New Providence yards alongside the open, sun-flooded ones a block away, giving each the cut it can carry. Granite curbs and mature plantings make for a great many edges, and the edge is where a property either looks kept or plainly does not. Trimming close, blowing off after, leaving nothing loose on the sidewalk — small things that add up to a yard with a defined shape. It is the sort of result you feel before you consciously notice it.
