Like other mulches, Walk-On Bark mulch serves many purposes in your garden. Walk-On can be applied on 2:1 slopes or flatter at a thickness of 2” – 3” deep. Walk-On Bark is shredded and adheres to slopes better than bark chunks that can roll. It suppresses weeds, neatens the appearance of landscape beds, conserves water and diminishes soil erosion. Walk-On Bark is a small chipped up bark that has a shredded look. It is brown with a reddish tint. This bark mulch comprises small, stringy pieces of bark and wood, approximately a half inch to 3/4 inch in diameter, and 2 to 4 inches long.
