Thank you for your reply, Gold1locks. It has given me confidence to be really drastic. (There isn't any other way, really! I will post before and after photos. It's going to be a big job, but I can't wait for the space it will leave me for new plants. I'm going to try and leave some growth which will hopefully grow to create a manageable barrier.
