Hi Laurie ~ I am not one to give advice. However, I will tell you what seems to works for me. When I receive any packages of irises in July or August, I pot them up and put them in my part shade "pot ghetto". Then they develop a good system of roots before fall as it is better for me to plant them then. Others may have other ideas. If they are in part shade, they do not need to be watered every day.
