Should I feed my mycorrhizae?

Molasses and other carbs are good for feeding bacteria and other types of fungi. But you don’t need to feed mycorrhizae. That’s missing the point. The plant feeds them! It’s the sugars from the plant roots that feed the growth of mycorrhizae and mycorrhizal filaments. (There are synthetic compounds that cause mycorrhizae to germinate, but they are unnatural, expensive and not commonly available.) The use of organic fertilizers, kelp, humic acids and other carbon sources are very compatible with the use of mycorrhizal fungi.
