The sphagnum method works best for me, I recently had 20 or so Musa Itinerans India form, and about 4 out of 10 Musa Thai black seeds germinate. I never had luck in soil. Since I had such good luck with the Thai Black, I ordered 50 more seeds from the same seller and started them a couple of days ago. It won't be much longer till yours get their first leaves. My India form are just now starting to get their reddish markings with this new leaf.
