I'm so glad to finally have peonies growing (25 of them!)as they are my VERY favorite. Sadly, the fragrance here in the dry SW isn't the best though. I was wondering if the dead/dried flowers should be left on the plants or snipped off? It has been many years since I lived in Iowa & don't remember how they were treated then.

Also, when does one know when to divide the plants? I remember my grandmother's must have been over 50 yrs. old & don't recall seeing her ever divide them. She always discarded the dishwater on the peony beds also!
