Thanks to Linda Mann and Colleen Modra for your
response. Linda, I don't think it was soft rot. The rhizome and roots
were in really good shape. The brown spots were dry. Maybe soft rot IS
sometimes dry, but I'm thinking not. Yes, 8 inches of rain is a lot,
but I live on a rock hill.
Colleen, I put out some fertilizer left over from last fall (18-46-0)
about a month ago, not heavy amounts at all because it was leftover so
it wasn't really enough. I will keep all these things in mind and
hopefully this will be a one time thing.

If it was at the end of summer, I would say it's
salt accumulation, which affect some cultivars more than others. Have
you used any new fertilizer or a heavy amount?

[iris-photos] Re: Culture
Can anyone tell me what is happening with this
iris? It is slowly turning brown from the top downward. None of the
other iris seem to be effected. I do not use herbicides or pesticides
so that isn't an issue. I do not have a neighbor close enough to be
causing this with herbicides and there are quite a few iris surrounding
it that should have been effected if that were the case. I dug it out
this afternoon and disposed of it. The rhizome was large and looked
healthy. Any help is appreciated.
Pearl in Texas where we received almost 8 inches of rain last week.
