Hi Patsgreen, which spray did you use please ?? I've noticed today mine has it as well.

I think you have to keep spraying at regular intervals to keep blackspot at bay. It should tell you on the packet/bottle. One spray doesn't do any good at all. Mine have all suffered really badly this year--it must be the weather! Annie
P.S. I use Roseclear on mine.

Use the same spray on those as well.
