I have two Peony plants, one in my backyard and one in my side yard. The backyard one only had one bloom while the side yard one had none. I have had both plants for over five years and this has never happened before. Any ideas what happened? Thanks for your help, Debra
It may be time to divide your plants. This fall will be a good time to do that. This can rejuvenate your plants.
You also can top dress the soil with some good organic matter.
