Hi, thank you for the responses. Only just realised I had replies when I found the emails in my junk folder!
I've bought some secateurs so will brave pruning it tomorrow. Just wanted to check if I should cut across one of the rings or above?
I meant pot the bit i'd cut off not repot the remaining bit. I've already got root growth off the few leaves I'd taken off just in case I get this wrong.
Typically the damn thing is growing very well now and as it should (leaves close together) now it's in a south facing window, making me more nervous of pruning it and killing it, it also looks like the top is finally branching out...I presume where double leaves are coming through that means they'll turn into their own branches?
