I've grown a variety of perennial geranium which I believe is NH Purple for YEARS....I have never known it to be anything but low maintenance. I just happened to be walking by an section of it that edges one of my beds and noticed it looked bad. I've attached some photos and I'm wondering if anyone can give me some insight on what disease might be the culprit. The 3rd photo is for comparison to the second - as the 3rd one is unaffected and dense as it should be....
Thanks so much!
