Am new here, and somewhat new to trying to grow irises.
I have some bearded irises that suddenly (within less than a week) showed this leaf damage. It doesn't quite seem like the iris diseases and problems I've seen on the web - looks a little like some tiny critter was munching. I searched in the daytime and at night with a flashlight for possible culprits but found no obvious guilty parties.
I live in southern California, in the mountains.
