It's a shame to have missed the display, and they were full of buds, too
Last year, a man from China listed peony recipes on another forum. People were fascinated, but were unwilling to sacrifice their peony roots to make dinner.
My Koukamon is in its second year of bloom. I don't know if that would make a difference. I think adding azomite can only help, too, as its just finely ground rock. The degree of microbial activity in your soil will determine how much of the product's mineral content will be available to your plants. I wonder how much is needed, as the product I have says you can't add too much! I'd like to conduct an experiment with peonies and how they are affected by certain additive fertilizers like Glacial Rock Dust (which is our azomite equivalent). Maybe I can next year if I can get a bunch of peony seeds to germinate. Let me show you how one of my peonies has changed (no bloom this year)(almost all soil replaced)
Same plant this year:
Look at how different! And my tree peony leaves seem to have something going on, particularly on what may be the weaker plants, that may indicate too much of something. However, I need to investigate it more because I'm having trouble finding information regarding the problem.
