Thank you, I really enjoyed this video. The last few years I've mulched my blueberry garden with lots of wood chips and inoculated the mulch with king stropharia mycelium. The blueberry bushes really seem to thrive in this environment and I had a ton of berries and mushrooms last year. I'm currently mulching my main orchard/food forest with wood chips, limestone rock dust/gravel and elm oyster mycelium, I'm also doing some of this mulching in my main vegetable garden now, too.
One small correction: I noticed John said "white cap mushroom spores", I think he meant to say "wine cap mushroom spawn". "Wine cap" is the other name for king stropharia, which is one of the best mushroom species for wood chip mulching and permaculture.
One question, does anyone know where to get azomite rock dust in Oregon for free?
As I understand, azomite comes from mines in Utah. Would not know of anyplace to get it free. Have you tried Concentrates near Portland? They carry it along with many different supplements. Great place to visit.
