I have an extremely thorny (the stems seem totally covered) yellow rose which might be a rambler of some sort. It is extremely vigorous and has grown to about 8ft in every direction since I last hacked it back last year. I forgot to take a photo of it in (very impressive) full bloom but here are shots of a single flower and of the bush today.
If it can't be easily trained, I think it needs to come out so any advice is welcome.
A trowel in the hand is worth a thousand lost under a bush.
