Walk On Bark is a natural forest product consisting of shredded Fir bark and bark nuggets. The shreds are screened 1" to 3" in length. Nuggets average 3⁄4" to 2" in length. Walk on Bark is a cost-effective ground cover for the commercial landscaper and is ideal for use in planted areas, where its shredded texture helps prevent the mulch from floating or blowing away. May contain thick dust particles that can stick to hands or feet (like fiberglass) when handled with bare skin.
