Question - when your peonys are done blooming do you cut the seed heads, like dead heading rhodos? I’d like to just neaten them up.
Well, THIS season the puppies ‘pruned’ them for me - and flattened them, and chewed off stalks, etc. I’ll have to take some pictures of the damage to the landscaping around the house. Next batch of pups, I’m finding a better place for them to be raised, other than on the front porch!
I know the Peony and the Hosta and Ferns and all the other stuff will come back, though!
So, yes, you can deadhead them as you would any other messy perennial. Keep the leaf mass though, of course! :)
