Disease

I recently read that the leaves on Mahonia Lomariifolia should not turn autumnal but I cannot remember what to do about it. I have Two standing at the bootom of my garden and one is still green but the other has yellow/red/orange edges to most of the leaves.

Pottylady (grief, where do we find these names?) Turn one of the leaves on the dodgy plant over. Are there brown looking 'pustules'? Get back.
