I was recommended I contact Oregon state by my friend from Schmidt Nursery to ask my question. I have a soil analysis from a 3 way blended soil that I am being told that is unsuitable plant medium. The supplier (grimms fuel) says they supply thousands of yards of this soil all around Portland metro. Can I email you my analysis and you tell me if this is acceptable soil?
