I am having a different problem with my irises. Some are just falling over at the base where the fans attach to the leaves. Looks very dried out, no smell or mushiness. I have read about crown rot and this is maybe what it is. I do not see any mustard seeds or white cottony stuff. We have had lots of rain, lots of early heat followed by freezing temps and now back to heat. I have just sprayed with daconil and Miracle Gro as I read about on Phil Williams Rockytop Iris site. We are not getting much rain now. It seems to pass us by. I have dug up two rhizomes that appeared dried out. The rest are here and there.
Any advice? Some beds are unaffected and others are sporadic in falling fans.
