Reviving a 50 year old peony bed
I have a wonderful old peony garden started by my Grandmother. I believe it has some vintage varieties that I haven't seen at the nursery. Over the last couple of years, it has started to dwindle and the plants seem stunted and give very few blooms. I have read that Peonies can live for 100 years. I'm looking for info on how to revive these beautiful plants. Any assistance or direction would be appreciated. Also, I'm looking for a phone number or email address for the Wisconsin Peony Society. I'm in Southern (Janesville) Wisconsin.
