Answer: Peonies should be cut down to the ground in late fall after frost kills the foliage. Usually, these take several years to recover from being transplanted and begin to bloom again so it is not surprising it has not flowered for you yet. In the meantime, keep it mulched with several inches of organic mulch and fertilize each spring using a general purpose or slow release granular fertilizer per the label directions. Top dressing with compost in spring can also be helpful. As long as it seems to be increasing and has healthy foliage, it should be fine.
