I planted wheat seeds and when they became plants, I dipped their
roots into mycorrhizal liquid, then I planted them touching the roots of my fruit
trees. Many
mushrooms fruited that were the mushrooms of the mycorrhizal spores, and I had never seen them before. It worked for me that way. The spores die if they don't connect with living
root tissue in 48 hrs. There are you tube videos on this. Search for growing mycorrhizal fungi.
