If I have done this right for the first time in my life, attached are photos of two of my strelitzia, each about 1.5 m tall and about 7 or so years old. They seem to be splitting into two or more plants. So do my other 4 although I won't trouble you with photos of them too. I have not seen any growing in the wild that look like this. I am tempted to take them out of their pots to see what the roots look like, but I wonder first if anyone has ever seen any develop in this way.
Should I separate the plants and put them in separate pots - for which I wouldn't actually have room - or let them continue as they are?
