Why are my peonies not blooming?
This can be due to several reasons, such as mulching or shift in soil in the garden. Peonies are very sensitive to planting depth. If the plant becomes too deep, as it does when mulched, the shoots (called eyes) that form at the top of the root (the crown) do not get their proper "winter chill" and cannot form flower buds. This lack of winter chill is why peonies do not grow in places such as Florida or Southern California. If you have peonies that are not blooming, check the depth of your peony by delicately moving a bit of the soil from the top portion of the plant being careful not to break off the delicate pink eyes. The top of the root should be from 0.5 to 1.5 inches below the surface of the soil. For details on the exact planting depth for your area, see the Planting section. If you find your peony to be too deep, it will need to be lifted. Transplanting is best done in the fall; moving it in the fall will also ensure that it gets the proper winter chill in the following season. Note that the first year after it is transplanted, it may not bloom as peonies take a year to recover from being transplanted. Don't worry, they are well worth the wait and will live for hundreds of years.
