These reddish-brown chunks of pine bark give your garden a neat, natural look. They break down more slowly than shredded materials, so they don't need to be replenished as often. Nuggets, which can be as large as 3 inches long, work best in flat beds, where they won't float away during a heavy rain. Also work perfectly in play areas or in wet areas to help keep down on mud. One bag is 2 Cu. Ft and covers 8-10 sq ft.
