I have lots of Sphagnum growing in my pots outside - not as much inside. I want to bring some cuttings in, but I'm wary of bringing pests into a warm, sheltered environment. There's already a population of miniature slugs that are constantly messing up my smaller plants, not to mention some obnoxious earthworms.
So, does anyone have a method for getting an aseptic culture of Sphagnum? Once I tried to wash some with rubbing alcohol, and it kind of worked, but I think I didn't rinse it enough afterwards because there was lots of die-off a few days later. Any tips would be great.
