South Berwick sits a few miles up from tidewater, close enough that salt air rides inland on an east wind and one storm can fall as rain down at Kittery and heavy snow right here. Oceanside Landscaping works both halves of that bargain: mowing, trimming and edging through the green months, spring and fall cleanups, leaves hauled off before the November rain packs them flat. In winter it is plowing — driveways and lots opened, walkways cleared, sand on the slopes that glaze over when the temperature swings the way it does this near the coast. A property cut sharp in July and passable in January belongs to somebody who watches the sky all year. That watching is the habit behind the work.
