WNC Wood Products. Inc. produces Sawdust and wood chips for industrial purposes in addition to other uses..

Landscaping:  Wood chips are great for flower beds and around the base of trees. 

Use:  At the base of a tree, create a thick ring with the thickest portion bear the truck.  Keep the chips about 2 inches from the tree to allow airflow to the entire trunk. 

Benefit of Wood Chips as mulch:  The benefit of wood chips over bark mulch is that chips decompose more slowly than bark.
