I repotted all of my nightshades yesterday into plastic pots, composting the newspaper ones into my weeds-only compost. The mold was clearly growing in the newspaper itself, and only then spreading to the soil. Hopefully, the move will help with the fungus problem. I haven't found my book on organic disease-curing in the garden (probably lost in the move, alas!)
Please feel free to ask questions - I'm always happy to answer. Leave a comment and I'll let you know all about it if I can!
More later (about kombucha). For now, endless amounts of data entry.
