Donald and Linda--
I am not knowlegable technically on this, but will share that when I lived in Kansas
there were many summer nights where the temperature did not get below the 70's, 80's
or even 90's sometimes and I had no problem with any iris I grew because of that.
The humidity is quite high in Kansas also (as I appreciate now that I am in a dry,
dry, dry climate). Don't know if this is anything that will help, but even with
daytime temperatures in the 100's and nighttime temperatures high too, the iris
didn't seem to suffer. I watered about once a week if conditions were dry. Too much
water may be the problem, although it doesn't sound like you are watering that much,
but iris don't like wet feet.
