Blommer shell mulch is made up of the outside shell of the cocoa bean. It is an attractive brown color which admits and retains water and never becomes soggy. When spreading, it stays in place, spreads evenly and never packs. Only 1-inch is needed to cover ground for weed control. Will not bleach out. It gets darker with age. One 2-cubic feet bag will cover 22-24 square feet at 1-inch thick.
