We have a couple of climbing roses either side of the front door. They were there when we moved in so I don't know what type they are. One of them suffers really badly from black spot, has very heavy blooms that the plant doesn't seem able to support and has blooms that turn brown before they open properly. It's straggly and frankly looks a mess.
I've pruned it heavily, tried to keep on top of the black spot etc - but this year it looks worse than ever.
It's planted in a small gap in the patio so presumably would be impossible to dig the roots out. I'm tempted to cut it right back to ground level this autumn and see what happens. Does anyone have any other suggestions?
