I can't confirm this. In our display beds, it's the unimproved bed that has
the worst spotting, and its soil is packed clay. The bed with much less
spot was tilled last summer and compost was incorporated. It's a lighter
soil. The plants growing from it are healthier-looking all around. They are
also much less crowded and set so they don't sit in mud, as the poor
critters in the neglected bed do.
Of course, we haven't seen what these plants will do after bloom. That's
when leaf spot really does its thing around here.
Still, hereabouts, it has to be a rotten year for leaf spot to be a big
Irises around here aren't the sissy plants our roses can be. Perhaps this
is thanks to the late-summer droughts. We often have one really dry month,
usually August, but it could fall anywhere in the year. Arkansas is
