Is Cutting Back Peonies Necessary?
In addition to the aesthetic considerations, the main reason for cutting back peonies is plant health. Peony diseases can be controlled by removing diseased foliage during the growing season, and by cutting back the entire plants after the end of the growing season in the fall.
Deadheading Peonies
Cutting back peonies is different from deadheading, which is the removal of the spent flowers after the bloom. If the flowers stay on the plants, they will produce seeds instead of storing all the plant energy in the roots, which ensures plant health and next year’s bloom. It does not matter how much you trim the flower stalks.
Removing Flower Buds
Newly planted peonies benefit from removing the flower buds entirely before they open in the first spring. Not every gardener eager to see the peonies bloom is willing to make that sacrifice.
Removing Peony Foliage
Cutting back peonies during the growing season is optional; it should be done as needed to prevent the spread of disease. Cutting back peonies in the fall, on the other hand, is always required.
Pruning for Disease Control
Two common fungal diseases of peonies are peony leaf blotch and powdery mildew. The spores of both fungi survive in dead leaves and infected plant debris through the winter.
Fall Cleanup
In the fall, cut the peonies back but wait until the foliage has died or fully yellowed after a hard frost. If you cut the peonies back too early, you reduce the time during which the foliage is absorbing sunlight to build the plant’s energy reserves. This will result in reduced bloom the next year.
