I'm new to the list and have been reading some posts about peonies. I have 4 of them in the yard of the house I just bought and have no idea what I'm doing with any of them...or any of the other stuff for that matter. I'd really like to learn, however! I was reading that if you have mildew/fungus on the plants they can be cut down in the fall. Is this something that should be done anyway? I'm trying to learn what needs to be cut down, what should be left, etc.
