Hi, I'm in zone 5b full sun with a beautiful 'Anne Thomson' cranesbill geranium in an in-ground flower bed. I water daily every morning. The plant is flowering and spreading out wonderfully but I noted some red on a few of the leaves. See photos of top and underside of one leaf. Is this the infamous geranium rust? I've only seen photos of geranium rust and I can't really tell here—with rust I would expect to see more signs on the bottom of the leaf but I don't see much there. Any thoughts? Thanks!
