Is there a way to tell if your yard/lawn/soil contains mycorrhizal fungi? I have a whole lot of mushrooms/toadstools popping up in my yard and wondered if it was because of the mycorrhizal fungi presence. I know many plants need this fungi to grow well and this includes citrus.

If I have a good supply of the fungi in my yard soil would it be possible to take a small amount and place it within a pot and have it colonize there? I have thought about purchasing some of the fungi but IF I can add it from my own soil it would be more economical.

This may be a far fetched pipe dream but I did have to ask.

Each genus of trees has its preferred fungi.
As you know, the ones that live in or around the roots
are called mycorrhizal fungi. It's a somewhat mutually
beneficial partnership.

So take some soil from around the roots of a mature tree
of the same species and put it on the soil next to the new tree.
Most likely you will inoculate your new tree with the beneficial
mycorrhizae.

I am doing an experiment with Plant Success
Premium Mycorrhizal Fungi, Granular. So far I have not
seen a difference between the with and without groups.
I am trying it with various citrus and tropical tree seedlings.
