By late October the light over West Islip goes long and silver, geese stack up over the marsh, and the causeway lights toward Captree come on before dinner. Shoreline Landscaping keeps lawns going right through it — cutting, trimming, edging and the autumn tidying that decides how a yard looks come April. South Shore grass gets a second wind in fall, and this is the stretch where steady mowing pays off months later. Leaves come off the maples in a hurry once the nor'easters start, so cleanups are timed to the weather rather than the calendar. The finish is simple: a lawn holding its green, borders defined, nothing blown back into the beds.
