How to Prune Peace Lilies

By Kathryn Hatter ; Updated September 21, 2017

Peace lilies are popular houseplants, despite being a challenge for many gardeners to grow successfully. In order to have a thriving peace lily plant, the environment must be ideal. Peace lilies require strong indirect light and consistent temperatures between 60 and 80 degrees F. Peace lilies also need regular water so that the soil is constantly damp but not saturated. Keep the peace lily healthy by performing regular light pruning to remove discolored leaves and spent blossoms. Gardeners who succeed in coaxing a peace lily to bloom should be proud of this achievement.

Check the peace lily at least once per week to find dead or dying leaves. When you find these leaves, clip them off at the point of the first leaf node under the leaf you are removing. Discard the cut leaves and stems.

Remove any spent flowers by cutting off both the flower and as much of the stalk as possible. Discard the cut bloom and stalk.

Examine the peace lily leaves to find leaves with outer edges that are discoloring or shriveling. If you find leaves like this, use the scissors to trim off the edges. Follow the natural shape of the leaves with the scissors and trim off the undesired outer portion of the leaves. Discard the trimmed away portion of the leaves.


Things You Will Need

  • Pruning shears
  • Sharp scissors


  • Prune the peace lily regularly throughout the entire year.


  • It is important to remove the blooms as they start to fade. If you leave the spent flowers on the peace lily, new leaves that grow will be smaller than average because the plant will be using energy to produce flowers and not to produce leaves.
