Landscape beds or planter boxes
Keep bark 2 to 4 inches away from plant stems and crowns to help prevent disease or pest damage.
Black Magic Planter Bark is a medium-coarse mulch made primarily from Douglas fir bark. It is screened for consistent size to effectively smother weeds while allowing air and water through to roots.
