Would this be beneficial to put in Orchid plants that grow in a bark medium?
I've just started using it on other plants last summer, but have acquired some orchids and am curious as to using it in the potting medium.
Thanks much, Jill
Actually, Orchids have their own kind of specialized mycorrhizae. Theirs is different from the other two kinds, and usually is systemic; i.e., it is there with the tiny Orchid seedling when it first starts out. I remember looking at Orchid root cross-sections in Plant Anatomy class; the Orchid roots were completely surrounded by fungal hyphae. The gray color of the Orchid roots is all fungal hyphae. The very tip of the root, the green part, is the "real" Orchid tissue. I didn't cover Orchid mycorrhizae in my article because you don't really need to inoculate them with it. They are "born" with it, as it were!
