I agree with Gabe, most of those methods arn't valid for bananas. I've personally cut off eyes off of one of my plants, by accident to get other pups off. Both eyes that had been cut had roots, one died, the other I think MIGHT come up still, but it's been over two months and it hasn't done anything.

If you want a plant to pup fast, you can cut off the corm to under the meristem or close to it (pretty much leveling it with the ground or soil in your pot), basically killing the plant, but it'll jumpstart the pup process. THEN wait til the new plants are around 12" (which could take as little as 2-3 weeks). Each time you remove a pup, a new one (if another hasn't already) should start sprouting out within a few weeks. Keep doing this process until the original corm just seems to be completely choped up... that's when it's been expended. You might even give up after a bunch of pups have already came up and been removed, then pull up the rhizome to put with your yard waste, and find that there's MORE eyes or pups that were under the surface. I'm still not highly experianced as I've only done this once, so I can't tell you how long this may go on. It could potentially in my eyes go on for 6 months or more. Give it a shot and see what happens!!!!

I recently tried this on a planted banana that hadn't shown any growth in 4 months and I didn't cut it low enough. Instead of pups coming up the main plant came back to life and is taller than it was to begin with. This was a month ago since I did that! I did have four rhizomes coming off of the main corm, but they havne't done anything since the main corm is recovering and giving all off it's energy to the mother. I'll get pups after no time though!

I like Gabes idea as well. It might go twice as fast by doing as I stated above, but only splitting the left over corm in half, but personally I'm (sorta) patient enough to just do it with the main corm left in tact. I also think that it would expend the corm faster by splitting it in half and you wouldn't get as many pups. Also be sure to have a good mixture of soil. I use a good drainage compost soil layered with manure. Usually I use ground soil, layer manure, put in the corm, compost soil, thin (1") layer of manure near the top, and top off with more compost soil. This works great for me. Good luck with whichever method you do choose and post your results!!!
