I wonder if a biofungicide like Serenade would work on iris leaf spot? https://www.groworganic.com/se... I guess I should try it.... a few of my irises are horror shows.
I agree with the observations that some of the irises are much worse than others, with regards to leaf spot.
Evaluating an iris seedling, hopefully for rebloom
