MJ...does fully composed bark count as "deadwood"?
If so, I would not be too hasty to discount the benefits of including bark as a growing medium ingredient (you help prove my point--thanks!). Many of the root cubes/plugs sold for cuttings (the dark colored ones) contain bark material. While weeding in my backyard, I noticed many of the roots were firmly attached to hunks of bark, unlike anything else. A few years ago I did a comparison of all available mediums and combinations thereof (about 25 in total) with objective to identify the fastest rooting medium; "orchid rooting bark" won hands down (just could not figure how to transplant a baby rooting clone growing in loose bark without fucking up the roots).
I paid just under $10 for a bag (2 cu ft) of small orchid bark today and is around 18% of my peat-based growing mix. I use both endo/ecto mychs for two reasons: product availability and cost.
BTW, I recall reading how ectomycorrhizal fungi has shown to control/combat certain plant pathogens and root rot issues.
