You all are so knowledgeable about Iris. I'm hoping you don't mind my picking your brains.
So far this spring I've lost 7 stalks to something.
I've looked online and haven't found any pictures of disease or critters that look similar to my problem.
There is no sign of chewing or boring. Just dryness at the break.
This has been happening when the buds are about to emerge from the leaf part of the stalk so the branch is somewhat heavy, falls over and breaks off.
Anyone have any ideas.? Thank you for your help! Ann
