Hello Gabriel, they are doing a lot better than my older ones. I only used a little pine straw as mulch to stop dirt from splashing on the foliage when it rains and it seems to be just enough to serve it's purpose without making hiding spots for more rolly pollies. I lost a few of my older ones because of rolly pollies and I lost a few to rot also. Thank you again for sharing some of you irises with me. If you ever go to dividing anymore please shoot me a tree mail, you know I'll be interested in some.
