Peace lilies (Spathiphyllum spp.) are popular houseplants because they thrive with little care indoors. Although they can tolerate low light conditions, peace lilies grow best in bright, indirect light. If you want your peace lily to bloom, it’s important to provide the right growing conditions and to prune it properly.

What You’ll Need

-Pruning shears
-Houseplant fertilizer

When pruning peace lilies, it’s important to use sharp pruning shears to avoid damaging the plant. You’ll also want to fertilize the plant after pruning to encourage new growth.


Because of their fast growth rate, peace lilies need to be trimmed back every few months to keep them from becoming overcrowded. The best time to do this is in the spring, just before the plant begins its active growth period.

Here are the steps you need to take to prune your peace lily:

1. Cut off any brown or yellow leaves with a sharp knife or pruning shears. These leaves are past their peak and trimming them will help keep the plant looking neat and tidy.

2. Cut the main stem back by a third, using sharp pruning shears. This will encourage the plant to produce new shoots and will help prevent it from becoming leggy.

3. Trim any lateral (side) stems back by half. This will help keep the plant compact and promote full, bushy growth.

4. Discard all of the cuttings in the trash – do not compost them as they may contain harmful chemicals that could harm other plants.


Pruning your peace lily is important to keeping the plant healthy and strong. With proper pruning, you can encourage growth, prevent disease, and keep your plant looking its best.
