Great advice, Arlyn. The local extension is there for the public. USE IT!
As to borers, I have never seen one anywhere in Arkansas or heard of anyone else that has had one in this state. I am glad. If I had seen an iris borer when I was a little girl helping Mama in her garden I would be over on some other plant site right now..... 'did you say iris. oh yes, my mother used to grow those.' lol
