I have a Truly tiny and a SDC (Super Dwarf Cavendish).

I have the SDC since last september. First he has grown well. Secondly he has made a lot of pups. I remove them all, destroying a lot of roots and repoted him in april.
He restart to grow since a month now. This week 14 pups have sprouted !

What should i do? If i remove them i will kill most of the roots.
My truly tiny tiny is growing fast and realy looks like a real banana plant but in 1/10 scale. He has a great pink coloration on the stem and petioles.
I think it is the not the real one, wich should be an extra dwarf brazilian, but a kind of SDC.
He made two pups this week. Should i pruine them ? I want him to flower !
