Why aren’t my herbaceous peonies blooming?

Answer

  • Young plants – peony plants can sometimes take up to 3 or 4 years to produce blooms
  • Small divisions – if a plant was recently divided sometimes it takes longer to produce blooms
  • Poor nutrition – peonies are heavy feeders and like heavy soils with some clay.  If you plant a peony in sandy or poor soil it will require fertilizer
  • Not enough sun – peonies prefer sun.  Shade for part of the day is OK, but they will be less likely to produce flowers.
  • Planted too deeply – peonies should be planted with the top eyes on the crown no deeper than two inches underground.
  • Disease – peonies don’t like wet sites!  Crown rot can slowly deteriorate the plant’s health and cause it to stop blooming.
