I've had the same with Musa sikkimensis (planted out) some years ago, really big plants already and no pups, while Musa basjo the same size was pupping like crazy.

Someone gave me the tip of boosting it with Potassium, so I did (giving it a few hands full of lawn fertilizer, rich in Potasium) and within a few weeks some pups started showing themselves! So appartnely it works, and there is no need to damage the mother pseudostem, although that will work as well.

Kind regards,
Remko.
