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?
