Hello,
First off, I'd like to apologize for the delay in response. We are a volunteer-run group and aren't always in the office.
Thank you for your question regarding transplanting Irises. They prefer full sun (6+ hours per day).
Please see attached Plant Talk link for more information on what we would recommend for transplanting and care.
