If you only want one plant there you will have to dig them up and separate them . Geez, no Roundup!

You might be able to find some people in your area that would be more than willing to take a few off your hands.

Please no Roundup.....Not an option in my book. Division only.

Call your local extension office of your university and ask the horticulture specialist if he has anyone in his group who would come and dig the plants for free bananas. Digging these guys is hard work, so if you can find someone who will dig them just for the plants, that would be the way to go IMHO.

I obviously hit a nerve with the Roundup! The people who don't like it - is it because you are averse to chemicals or because you can't stand the idea of killing a banana plant?

I rarely use chemicals but have the thistle invasion from h*ll, so I've been using Roundup on them, and on the chameleon plant that is taking over the world.

Digging the bananas is a REAL challenge because they are in this skinny strip of land between the house wall and the pond - I haven't fallen in the pond yet but it's only a matter of time!

I would worry that in using it, you might damage the corm and lose whole mat.
All other Roundup issues aside, I have concerns about using Roundup (an indeed, many other garden chemicals, too) near *water*.

What happens if you just start cutting off unwanted pups soon after they emerge?

seahorse, I wondered about cutting off the pups as they emerge too. Does anyone know if that would solve the problem, or would it just encourage them to pup more?

Good point about Roundup near water - too easy to spray a bit in the pond, very bad for the fishies!

If I lived near you I would be happy to solve your problem - I'll bet there are others who feel the same way.

"Free bananas, you dig"

In my experience, cutting off pups as they emerge causes no damage to the parent banana plant. The only thing that happens is that the pup you just cut will send out another leaf from the shaft. The only way around this is to cut the pup FROM the corm. Bananas are like weeds in the sense that it's hard to kill em. ( Crapyy good for NOTHING winter weather aside). If you mow em over with the lawn mower, they'll come back!
