Autumn reaches the Muttontown edge of Oyster Bay as a slow turn of color in the oaks and hickories, a week of gold before the wind takes it back. Castlewood Lawn & Landscape spends those weeks mowing what is still growing and hauling off what has already let go — beds cut back, borders redefined, leaves lifted out of the ivy. A lawn cleared properly in October looks like it is sleeping rather than neglected, and that difference is the entire point. The ground here rolls; the hollows hold damp long after the ridges dry, so no two yards on a street get the same pass. Come the first mild stretch of spring, the difference shows on its own.
