Q.spotted and brown iris leaves

Zone Marion, IN | Anonymous added on June 14, 2020 | Answered

We’ve had too much rain this year for my bearded iris. They are old antique plants that I don’t want to lose, but some of the leaves are turning brown and some of them are spotted which looks like rust. Can I cut those leaves back now? Is there anything else I need to do to make sure I don’t lose these plants?

I hope this is simple leaf spot, but it could also be more troubling, especially since you've had an unusual amount of rainfall. Here is an article on iris roots that may be helpful: https://www.gardeningknowhow.com/ornamental/bulbs/iris/rotting-iris-roots-bulbs.htm

And here are a couple more articles that may help if the problem is not as serious:
