I have several growing from the base of my one. The trunk looked soggy so I cut it down to half size, then it started shooting these babies. I was terrified of splitting them apart and losing them all, but if it's that easy I'll give it a try.
P.S. Mine are still in a cold greenhouse and not sure when to bring them outside. Especially don't want to lose the pink stripey one-'electric pink' I think it is. Should I wait till all frost gone?
