They do tend to grow large so I'd have a go at separating them. I had them
growing in my garden in SA - one was up to the top of the house & needed
constant trimming.
I've never considered them to be that fragile.

I have six bougainvillea cuttings in a 6" pot - three different
colours, species / variety unknown. To my consternation they have all
rooted. I am told that they have very delicate roots and transplanting
is a high risk business. I'd be entirely happy to leave them all
together and treat them as one plant. Is this feasible? If not do I
transplant asap or give them time to build up stronger root systems?
