I have just noticed some blackspot on the leaves of my climbing iceberg rose. I have done some research and most say to start treating in spring, however, I'm wondering if there is anything I can do now to stop the disease overwintering? thanks

There is a little you can do; pick up and burn all fallen rose leaves everywhere in your garden. That's where the disease can overwinter. Otherwise any spraying will be a waste until spring. Hope that helps!
