Well, mums rambles, climbs, twines and manhandles its way along her fence, through the trellis and up into the neighbours rose! She has never ever done anything special and it gets covered in white flowers, anytime soon actually. Mine are still babies like yours, altho they have really perked up since I put them in bigger pots. I am thinking of growing one as a standard, like you sometimes see Wisterias, and the other one I am going to pretty much leave to it. I believe that like a wisteria, once it has finished flowering, you should cut back all the whippy branches, or if it has set fruit, you cut them back to the fruit....but don't quote me, mum has never had a fruit in all the....um...well at least 10 years that she has had it, and she does have a boy and a girl, allegedly!
