Arlene, I never even looked for suckers! Silly me! That sure would be easy enough. I'll check in a little bit, and I'm so glad you mentioned it!
Thanks for the great info Caroline. Should I wait until after they are done blooming? I would have never thought to use sand, so I'll pick some up next time I'm in town. I do have rooting hormone, which I love for everything else I've rooted!
