Like many other plants - I think thinning would help the whole since you'll have better light to those you leave attached, and you'll have better air-flow, tho I'm not aware of any foliage fungal problems with nanners. If you have too many of them all bunched up, some are going to be shaded and will likely not be contributing to the corm. Much like suckers on fruit trees or bull canes on grapes.
So, my guess would be to cull out those pups that are not in a position to directly benefit the plant (light is power - if it's not getting light, it's sucking energy). And... well, I'll help you dispose of those pups.
Oh... topping. Sigh.
Well - I'm not sure how far you need to top it to keep it from growing back, but it seems that portions of the corm that don't have pseudostems attached degrade. For instance. I had one planted in the ground out back that I dug up to replant. The main pseudostem had died back for the winter and a new pup was growing. The main corm had rotted out as the new corm developed under the pup. So - living pseudostems may be required for that section of corm to remain. If you cut it, the energy may be sucked up into the growing sections. Just a guess here... I think the most important thing is to ensure that all pups are or will become contributing members - they all have sun and are not crowding out their siblings. Those that appear to be problem-pups would likely be candidates for culling...
But - this is just a guess - I really hope someone with more direct experience with nanners will pipe in...
Be well,
Mike

Let try this again! lol If you already have enough pups growing for next year and the year afters plants, but still have more pups popping up all over the place, should they be topped to allow the mother corm to absorb the unwanted pups corm energy. Is this making any sense?
So my point is would topping the extras give more energy to the mother plant verses completely removing them for resale or planting elsewhere.
