You can water it in or put it in your soil
I was building my super soil when I asked my grow store guy about it and he recommended it as he uses it himself
He said he was not sure about me putting it in my supersoil soil build but added that it seemed like it wouldn’t hurt
Here is a good read. While the affects of mycorrhizae in no till application is completely different, using it just in soil can inhibit the growth of plants when using high ppm of phosphorous.
which are beneficial? Some products have both endo mycorrhizae and ecto-mycorrhizae listed on the label. Ecto mycorrhizae inoculum has huge spore counts with concentrations of 80 million or more per c.c. It is therefore inexpensive to add a little and report large spore counts in a product. They are however only of value to most conifers and a few hardwoods. Endo mycorrhizae forms beneficial associations with over 80% of all plants including most commercial fruit and vegetable crops (except the brassica (cabbage), chenopod (spinach and beets). Pigweed and other members of the Amaranthae family are also not able to form mycorrhizal associations.
