How to propogate Nuphar japonica?

[vinz]

Does anybody know how to encourage N. japonica to put out new "plants" from their tuber? The one I've got probably has a tuber about 4ft long in total and has about 4 or 5 "plants" growing off it.

Can I notch the tuber, like the technique of notching Anubias rhizomes to encourage side shoots? I can't dig it up, notch it and replant as it'll be too big a mess. So, I'm wondering if I can let tuber segments float or sit around in a tank and wait for new shoots.

Why dun you cut one segment with some plants in it and grow them emmersed? It will be faster that way.

I don't think N. japonica grows emmersed.

I've tried some searching for info... all I can find describes them in submersed form and no mention of emmerse form except for emmersed (floating) leaves.

Check with Teo... He grows them emmersed...
