my peonies barely bloom
We have some very old peonies that we transplanted from our old house when we moved to a new one five years ago. They keep coming up year after year, but last year was the first time since we moved here that we got any blooms at all. I think we had a grand total of 5 or 6 smallish flowers. I've heard that peonies can live to be very old and still produce flowers, so what's wrong with mine? I fertilize in the spring, but maybe I'm not using the right stuff. Help!
