Before pruning your peace lily, it’s important to understand what you’ll be doing. This tropical plant is native to Asia and thrives in humid environments. It’s a common houseplant because it’s easy to care for and can tolerate low light conditions. When pruning, you’ll want to remove any yellow or brown leaves, as well as any flowers that have wilted. You can also remove any stems that are longer than 12 inches.


1. Peace lilies (Spathiphyllum spp.) are grown for their large, glossy, dark green leaves and white blooms that appear throughout the year. They’re easy to grow indoors in pots and thrived in low-light conditions.

2. When peace lilies start to outgrow their pot or become leggy, it’s time to prune them back. Pruning will encourage new growth and help keep your plant healthy.

3. To prune your peace lily, start by cutting back the long stem that holds the flowers. Cut the stem back to about 6 inches (15 cm) above the soil line.

4. Next, cut back any leaves that are yellowing or browning. Cut the leaves back to the main stem, taking care not to damage the healthy leaves.

5. Finally, cut away any dead or damaged roots from the base of the plant. peace lilies have a tendency to produce a lot of roots, so you may need to remove several before you’re done.

6. Once you’ve finished pruning, water your plant well and fertilize it with a balanced fertilizer according to package directions.


To keep your peace lily looking its best, prune it regularly. Getting rid of old, dying leaves and flowers will encourage new growth. You can also cut back leggy stems to create a fuller plant. Pruning is easy to do and only takes a few minutes. With a little care, your peace lily will thrive for years to come.
