Strelitzia Reginae help
I have three plants in my conservatory that I've grown from seed. They have split and flowered a number of times (I can't remember how old they are now). My problem is that two of them are pushing themselves out of their pots. I could buy bigger pots, but I'm running out of room. Is there any way to restrict their growth? Can they be root pruned? Any one else suffered this?
