Sawdust for amending soil?
I am in the process of making a new 25' x 13' raised hosta bed (finally got rid of our wooden playset)!!! My dad does alot of woodworking and has bags and bags of cedar, oak and pine sawdust. I was wondering if anyone has used, or knows if this would be a good thing to amend in with the soil?
Also--could I use it in pots along with a perlite and peat moss mixture for a potting medium?
Thanks in advance everyone!!
