Mycorrhizae - for free?

[PepperWhisperer]

Today I was transferring one of my "extra" seedlings to the ground and in the little hole I dug for it I found some stray roots, probably from the nearby persimmon tree...totally busting with mycorrhizal colonies! At that moment I felt almost like I had struck gold in my backyard. I am now trying to figure out how I can propagate the magic little spores to the rest of my garden. Looking around on the internet I found this interesting set of instructions

Anyone think this will work? Or are there better ways to multiply my fungi?

thing is you could be breeding a lot of other things along with myco, also it seems like a lot of effort when 2 ounces of myco is $4

Even if it breeds anything else it doesn't matter because he is still putting the plants in the ground with the other bacteria and fungi
I say go for it

What could I be breeding that would be bad for my plants?

I don't think anything but I'm not a fungus and bacteria expert. I say go for it I almost guarantee your plants will be fine if not better
