Shame, the red one looks lovely. However, if you have to, dormant season, when leaves have dropped. And sympathetically. Phil J

Thanks Phil I have been pruning slightly the last couple of years!! but they do need some drastic cutting back as they are now getting intertwined.

You will need to let your inner bonsai artist out, Maggy, because they don't always take to being stubbed back. You may have to do it in stages over the next 3-4 years.

Thanks !! I wonder if that is why the one I have/had in my raised border has withered and looks dead?? I might have cut that a bit drastic as it was growing over the back path.
