Welcome Subnoise and CC. LOS Sue Style. That's sweet.
It's an honor to have so many organic growers subbing.
CC, I'm planting this time without removing the rootball. I expect the new plant to simply take advantage of the available pathways and attached myco. Roots dissolve fairly easily, although I do like your idea of adding Kashigro to ramp up the composting action. It would have to be timed so as not to interfere with the germinating seed. This is my first attempt at this and I realize I'm only in 7 gallon pots, but I expect it to work out nicely. We'll see in a few days.
CO, I just cut the main stem off right above the soil level and left it to rot. Maybe I'll get lucky and have some mushroom action happen. We're learning as we go here.
