You mean Rotten Cotton? I work as a mechanical Insulator and have access to this.

Rotten Cotton ??? !!!!! I haven't heard that term in a while !!! That's the itchiest, scratchiest crap I've ever run into. Why would anyone want to punish innocent, tender apple tree roots in that stuff ???

We did a huge job with it two summers ago insulating outside ductwork in the heat of summer, talk about a miserable ride home!

We used a rockwool rooting media many years ago in the greenhouse industry but it never caught on

I had to Google it... seems to be popular with marijuana growing for hydroponic systems, didn't come across anyone using for fruit tree growing. Try it and let us know
