Should Peonies Be Pruned Back In The Fall?

Fall is the ideal time to prune herbaceous and Itoh peonies, as they show signs of wilting and need to be pruned to prevent common issues and promote robust growth for the next spring. Herbaceous peonies should be cut back in the fall between October and November, after the first frost and when the foliage has turned yellow. This is crucial for their health and the best spring blooms.

For tree peonies, the best time to prune is right after it blooms, but not in the fall like herbaceous or Itoh peonies. Herbaceous peonies should be cut back in the fall after the first frost and when the foliage has died or fully yellowed. Cutting them too early may reduce the time during which the foliage absorbs sunlight to build the plant’s energy reserves, resulting in reduced bloom the next year.

In the early fall or after the first frost, it is the ideal time to cut back the plants. Cutting peonies in the fall helps remove foliar diseases and reduce infection. Peonies should be cut back at the beginning of fall as they are very prone to fungal infections and will most likely flower again and re-grow.

In summary, pruning peonies in the fall is essential for preventing common issues and promoting robust growth for the next spring. It is important to wait until the foliage has died or fully yellowed after a hard frost, as cutting them too early may reduce the time during which the foliage absorbs sunlight and builds the plant’s energy reserves.
