A large group of peonies were thriving when we bought our house in N Central NJ 10 years ago. Now some seem to be failing - some of the smaller plants have simply disappeared, the larger ones are much less full than in past years. We had a weird warm spell in January where many flowers came up and were on the verge of blooming, then another cold snap. Could this have stunted the peonies? What can I do to bring them back to health?
