Mulch Materials

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.

Earthgro Pine Bark Nuggets, also at The Home Depot in selected stores, $2.99 per bag (2 cu. ft.).
