Cedar MulchEnjoy the aromatic essence of organic Albertan Cedarwood. Adding mulch to your yard can reduce the need for watering and can be used as a natural weed barrier with a minimum depth of 6. As mulch decomposes, breaks down and is exposed to the elements, it will need to be topped up to maintain coverage. Mulch is a wonderful way to create different focal points throughout your yard, adding it to your garden, yard decoration, or tree rings.
