frequently asked questions

  • What are the different types of peonies?

  • Why aren’t my peonies blooming?

    • Plants could be too young. Peonies are long-lived perennials that follow the adage, ‘first year roots, second year shoots, third year flowers.’ Give them time to mature.

    • They aren’t getting enough sun. Herbaceous and intersectional peonies need a lot of sun to flower, preferably all day. Tree peonies need mottled sun all day or a half-day of sun. Woodland peonies need to be in a deciduous woodland where they get early spring sun before the leaves come on the trees.

    • Planting depth. The flowering of herbaceous and intersectional peonies is incredibly sensitive to planting depth - too deep and plants won’t flower, too shallow and plants will dry out and die (details on herbaceous planting depth, details on intersectional planting depth). Do not mulch your herbaceous or intersectional peonies! This will cause them to be too deep and stop flowering. Tree peonies are also sensitive to planting depth but in a different way than herbaceous and intersectional peonies (details on tree planting depth).

    • Peonies budded but did not bloom. In addition to the factors above check for: poor soil (get your soil tested), excessive moisture (peonies require well-draining soil), and early spring frosts (frosts can damage bud formation). Examine these factors and adjust as you can.

  • Where can I plant peonies?

  • My new peony was growing well in early spring and then died. What happened?

    • Your plant is likely not dead. It may have just been stressed and the top gave up but the roots are still alive. Follow the steps below to improve your chance of success next spring.

    • First check how it was planted and make sure it was planted to the proper depth, in the proper location, and with the proper orientation (not upside-down). Click here for herbaceous peony planting, intersectional peony planting, tree peony planting, and woodland peony planting.

    • Next consider water. If your peony was newly planted it may have been stressed by drought causing the top to die back and the plant to focus on root growth. During the first growing season after planting a new peony ensure it gets a good soaking at least once a week especially in the heat of summer. Weekly soakings keep the plant from being stressed by drought as it develops its fibrous root system.Be careful to not over water. Over watering or use of foliar/overhead sprinkler systems can cause disease.

    • If your peony was not planted in well draining soil or if it was planted in an area that flooded there is a chance your peony root has rotted. Check the root to see if it is alive and if so move it to a better location.
