Rose leaf fading colour

Question from Naushin

One of my roses has recently been affected by black spot. Having looked at images online this was easy to identify . I do, however, have another rose (Gertrude Jekyll) which has fading coloured leaves . Is this black spot also ? It doesn't seem quite so obvious as a new gardener !

blackspot on climbing iceberg

Question from karen evans

hello,
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
