Ok - so I guess it's 'southern' because we have the happy opportunity to have
more of it more often, and probably more different kinds.  Good ol
biodiversity.  Yup, this last 2 inches of rain in 24 hrs has set it off
again.  Definitely worse in the beds where the soil has settled longer.  It
always seems at its worst here when iris are growing fastest, which is not
during the heat of summer, but more late spring, early fall.  

Any anecdotal information out there on whether or not there is more rot or
less rot with high densities or low densities of earthworms?

I hope this shows up in future intros from Schreiners, that they take this
'opportunity' to identify some good rot resistent strains.

Good for you.  Me too.  Although I do mourn the passage of some.  I really
wanted to see FALL FIESTA bloom, but not enough to doctor it.  Looking for
varieties never AFFECTED (a little tougher criterion than never KILLED)  by
erwinia has been what got me here.  About the time I think I 've found
another tough one, I move some to a slightly different growing condition, and
down she goes.

Thanks for the info Lloyd.
