How to care for peace lily

  • Light: Prefers low to medium indirect light; direct sunlight can scorch its leaves. Too little light may prevent blooming.
  • Water: Water when the top inch of soil feels dry, or when the plant starts to slightly droop. Ensure good drainage and avoid overwatering.
  • Soil: Needs a rich, well-draining potting mix that retains some moisture. A standard houseplant mix with added perlite works well.
  • Temperature: Thrives in average indoor temperatures between 65-80°F (18-27°C). Protect from cold drafts and extreme temperatures.
  • Humidity: Enjoys high humidity. Regular misting, a pebble tray, or placing it near a humidifier will be beneficial.
  • Fertilizer: Fertilize every 2-4 weeks during spring and summer with a balanced liquid fertilizer diluted to half strength. Reduce feeding in fall and winter.
  • Propagation: Best propagated by division during repotting. Gently separate sections of the plant that have at least 2-3 leaves and roots.

Is peace lily toxic to pets?

Not pet-safe. Peace Lilies are toxic to cats, dogs, and humans, containing insoluble calcium oxalates that can cause oral irritation, burning, swelling, and difficulty swallowing if ingested. See our guide to toxic plants for cats and dogs.

Common problems

  • Yellow leaves: Often a sign of overwatering or nutrient deficiency; adjust watering schedule or consider fertilizing.
  • Brown tips on leaves: Typically caused by low humidity, over-fertilization, or irregular watering; increase humidity and water consistently.

Did you know?

The white 'flower' of the Peace Lily is actually a modified leaf called a spathe, which protects the true, tiny flowers on the central spadix.
