Catt out grew Semi-Hydro

[Tindomul]

So I am wondering what I did wrong that the plant preferred to send out roots into the air than to keep growing in the pot. Check this Catt. mossiae "Pauwela Passion" x self.

It has not bloomed for me (Uhmm, at least I don't think it has).
So my question to you is, would you repot this in s/h, divide it and pot the divisions in s/h, or pot them in different media? Or do nothing at all?

Also I have removed half the roots you see because they were yellow-brown.

THanks,

César
