I think I'd prune it as usual and give it a dollop of Rose fertiliser or similar
Thanks, I'll give that a go. I did try some anti fungus spray at the end of last year as it looked so awful covered in powdery mildew, but didn't seem to make much difference. Hope it's better this year, it's a cutting from my Dad's plant that I've had for about five years and usually it is fantasic.
