I have so much leaf spot. My question: If irises are grown far enough apart will they not spread it? I have one plant growing separately in another garden that doesn't have it, whereas all of the plants planted together in my main iris bed have it. I remember someone here saying that he just ignored his iris bed for most of the summer. I saw a lot of rot starting earlier so I dug those plants and cut out the bad parts but left most of the clump sitting on top of the ground. Then I walked away...Like I said, they are all a waterspotted mess, which only constant removal of spotted leaves through the summer seems to prevent. I can't find the time/energy to constantly maintain my irises so they always look good.
Anyways, I went back to the messy bed yesterday, and found that the ones I had dug and left in a clump had been growing roots all along, so I guess this is a quick stop rot option. There were a few that I dug earlier thinking that I would divide and replant right away, but I never got around to it. Those of course, have not been growing roots so likely they will take longer to become re-established.
