New nursery looking for thoughts on container soil mix
We will be container growing a variety of products but mostly shade trees. The volume of soil required will be quite high so we are looking at ideas of materials we can truck in fairly cheap if possible. I realize certain products we will have to spend on.
I have a nearly endless supply of fescue lawn clippings as well as owning a farm, we bale hay. It is hard to justify good quality hay for this but I might be able to get old hay, corn stocks, etc for this. I do not have a shredder though and I assume that will be required to get a reasonable breakdown time.
I was going to order in sand and Perlite but sort of concerned Perlite will be too expensive.
