Answer: Peonies can fail to bloom if they are overcrowded, if they were planted too deeply, if they get too much nitrogen fertilizer or if they are too young. A three year old plant should be blooming so perhaps it is planted too deeply. Wait until frost kills the tops down this fall and then dig and replant your peony so that the eyes are only a few inches beneath the soil surface. Don't feed your peony with a high nitrogen fertilizer this year or next. Instead, use a bloom booster fertilizer (high in phosphorous and potassium, low in nitrogen). Hope this does the trick!
