I'm seeing symtoms of something in a few of my bearded iris that I've never seen before. 3 or 4 of my varieties have yellowing leaves with brown spotting. They are also blooming beautifully. This is my third year living and gardening here in this woodland environment and the first year I've had a striking bearded iris display. When the symptoms showed up on the first, it was one that has a lot of vinca minor as a ground cover around it and I thought the rhizomes may need more sun on them. A few days later I noticed it on a couple more that have good air circulation and no ground cover around them. Any ideas what the problem is and what to do about it? I'll try to post some pics.
