Well, I've given up on trying to find pine bark fines to make my own potting mix...they just don't exist in the Tampa Bay area. Before I had some idea what I was doing I bought a yard of "potting soil" from a local Topsoil distributor and it was awful stuff, had topsoil and sawdust in it.

Anyone in this area have a local nursery that makes or offers bulk in what you consider a well draining potting mix?
