I have a fairly new, but large, Red Robin, planted last autumn. It seemed healthy then but now the leaves have black blotches. Is this a form of blackspot, and if so, what is the best treatment? An older one nearby is fine.

Thanks, Verdun. Actually the new one is more sheltered than the old, but it is on the north side of a high fence, and the ground there can be wet - particularly recently!
