I posted this question. In the cottage section. The responses did,t help. My peony is about 13. It used to have lots of blooms. The last two years zilch. It gets morning sun. Then part sun. What should I do!
Almost every garden gets less sun as the trees mature. Thirteen years could mean quite a change in the sun on your peony. It also is possible that the soil is now higher on the roots and is preventing the blooming. This fall I would dig and divide it, replant divisions at the right level where I am sure of enough sun. Al
