In this section, we answer frequently asked questions about why peace lily leaves turn yellow.

What Causes Peace Lily Leaves To Turn Yellow?

  • Overwatering or underwatering: peace lilies don’t need frequent watering, and overwatering or underwatering can stress the plant, causing yellow leaves.
  • Too much direct sunlight: although peace lilies can tolerate low light conditions, too much direct sunlight can damage the leaves, leading to yellow leaves.

Yes, yellow peace lily leaves can be trimmed. If leaves start to turn yellow, trim them using sharp, sterile scissors. Always cut the leaf at the base, and avoid tearing the leaf or cutting too close to the base. Keep in mind that yellow leaves may be a sign of an underlying problem.

If the problem persists, it’s best to treat the plant before trimming it to prevent further damage.

Is Wilted Peace Lily Caused By Under-Watering Or Over-Watering?

Both overwatering and underwatering can cause peace lilies to wilt. Overwatering causes root rot, which leads to a lack of oxygen in the soil, causing the plant to wilt. On the other hand, underwatering causes the peace lily to wilt because it’s unable to take up enough water to keep its leaves turgid.

Keep these points in mind to ensure that your peace lily stays healthy and doesn’t develop yellow leaves. Happy gardening!


To sum it up, yellow leaves on your peace lily can be an indication of different issues. Often it’s due to overwatering, improper lighting, or the lack of proper nutrients. Getting to the root of the issue can help solve the problem before it gets worse.
