Q.spotted and brown iris leaves
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?
