Hard to tell what your situation is without a photo. You don't say how large your plants/pups are. What is a 'water leaf pup'? Are they all in the ground now, or in pots? If in the ground, why are they fighting for resources? If you must separate all those pups, make sure you slice off a part of the mother corm (that has roots).

Yes, I should have provided the picture in the first place. How lazy I can be.

Here is the "old corm" last fall in November. This is after digging up and removing my three large bananas that filled the yard. The stump is actually 2006s big plant.

Here it is now:

I am glad that it revived but I would rather had a few large plants. There are seriously 8 or 9 pups. I would love to put them in the ground but I don't know when we will move. So they have to stay in pots. So I guess I am just going to cut right down the middle and separate into 2 equal pots. Just wasn't sure what you guys do when this happens. I guess if I was going for individuals for sale I would cut it like a pie and assume they won't take it as hard as a pup being separated from it's mother. We'll see if they take a single cut hard at all.

If I were you I'd plant that whole mass of bananas in the ground. Don't even brake them off. Just plant the whole thing as is. They all look nice and healthy by the way. I have 3. Two in the ground and 1 in a pot. Believe it or not the one in a pot is starting to pup out. Also when you say "water leaf pup", are you talking about (sword suckers) and (water suckers)?
