Has anyone tried Mycorrhizal Fungi with cuttings? I use it on all kinds of new plantings, and I am thinking about adding it to the water I give newly potted-up cuttings to help develop more fine root development. Any ideas?

I have been and seen definite increase in growth, I have been adding it and purchased potting mixes that have some in it...

I use mycorrizae pro mix. More importantly I use mycorrizae crystals sprinkled around the roots when I up-pot my cuttings, that is the best way to benefit the root system.

Gene,
There had been a few topics started on the subject. I use Espoma Tone fertilizers with Mycorrhizae and Beneficial Bacteria in 1 gallon and larger containers. I never use it in the early rooting stages, because of a concern of introducing harmful microbes from the organic fertilizers too early in the rooting process.
