Peony buds never bloom
I have a peony that hasn't bloomed since the first year I planted it. It is 5 or 6 years old now. It looks very healthy and gets buds each spring and then they never mature and bloom. I spray it with copper just in case it was from botrytis. I dug it up last fall and lifted it a bit just in case it was too deep. It is in full sun and right next a peony that blooms every year that is about the same age.

Thank you for your question. It is difficult to diagnose a plant problem without photos or being able to examine the plant. Botrytis may well be the problem; here is a page from our diagnostic manual on that disease: https://pnwhandbooks.org/plantdisease/host-disease/peony-paeonia-spp-botrytis-blight Perhaps you can take samples and photos to the Extension office while the problem is occurring next year, and we can help. Good luck!
