What do you have available without it being ordered and/or shipped? I use pine chips, but that's because it is what is around and what I can get for free. When a chipper dumps a load off on the side of the road somewhere, it gets shoveled into the back of a pickup and brought home!Is there a specific kind of wood chips? I may order wood chips and some pine mulch as suggested by goldysgirl
Use what you got.... it doesn't have to be expensive.
