Incessant wet weather is a real problem for containers. Most geraniums (pelargoniums) showing signs of leaf blotches on several leaves.
Although not absolutely certain (see update), don't think this is disease. Concentric scorch marks indicate sun scorch caused by hot sunshine shining though rain drops (which act as a lens).
Never seen them so large before, so not ruling out disease. But normal leaf blotch does not have the scorch rings. Shall have to wait and see.
Sprayed with 'Dithane' just in case. Might help. Hope it clears up soon (the weather, I mean).

Actually, The sun shining through water drops and acting as a lens, is an old gardening myth that just won't die. The concentric rings you see is from Early Blight..a disease.
Thanks for the comment. I appreciate what you are saying and completely agree. Shortly after posting, I found a reference to fungal leaf spot which had an almost identical photo. I posted re this and placed a link ("see update") in this post. Sorry for any confusion.
