Peace Lilies (Spathiphyllum) are beloved for their elegant white blooms and lush, glossy foliage. Known as one of the most forgiving and air-purifying houseplants, Peace Lilies are perfect for beginners and experienced plant parents alike. Whether you're caring for a classic Peace Lily, or the variegated Domino Peace Lily, this complete care guide will help your Peace Lily flourish and bloom beautifully.
Quick Care Summary
- Light: Low to medium, indirect light
- Water: Keep soil consistently moist, allow slight drying between waterings
- Humidity: 40-60% (moderate humidity preferred)
- Temperature: 65-80°F (18-27°C)
- Soil: Well-draining, peat-based potting mix
- Toxicity: Toxic to pets and humans
Light Requirements
Peace Lilies are remarkably adaptable to low to medium, indirect light. They can thrive in north-facing windows or offices with fluorescent lighting, making them ideal for spaces where other plants struggle. While they tolerate low light, Peace Lilies bloom more frequently with brighter, filtered light from east or west-facing windows.
Avoid direct sunlight, which will scorch the delicate leaves and cause brown, crispy patches. If your Peace Lily isn't blooming, try moving it to a slightly brighter location.
Watering Your Peace Lily
Peace Lilies are excellent at communicating their water needs - they'll dramatically droop when thirsty! Here's how to water properly:
- Water when the top 1-2 inches of soil feel dry to the touch
- Water thoroughly until it drains from the bottom
- Allow the plant to droop slightly before watering (they recover quickly!)
- Use room-temperature, filtered or distilled water when possible
- Reduce watering frequency in winter when growth slows
Pro tip: Peace Lilies are sensitive to chlorine and fluoride in tap water, which can cause brown leaf tips. Let tap water sit overnight before using, or switch to filtered water for best results.
Humidity & Temperature
Peace Lilies appreciate moderate humidity (40-60%) but adapt well to average home conditions. Increase humidity for optimal health by:
- Misting leaves 2-3 times per week
- Placing the pot on a pebble tray with water
- Using a humidifier nearby
- Grouping plants together to create a microclimate
Maintain temperatures between 65-80°F. Peace Lilies are sensitive to cold drafts and temperatures below 60°F, which can cause leaf damage and stunted growth. Keep away from air conditioning vents and drafty windows.
Soil & Potting
Use a well-draining, peat-based potting mix. An ideal blend includes:
- 50% peat moss or coco coir
- 25% perlite or vermiculite
- 25% high-quality potting soil
Repot every 1-2 years in spring when roots become crowded or grow through drainage holes. Choose a pot 1-2 inches larger than the current one. Peace Lilies actually bloom better when slightly root-bound, so don't rush to upsize.
Fertilizing
Feed your Peace Lily during the growing season (spring-summer):
- Use a balanced liquid fertilizer (20-20-20) diluted to half strength
- Apply every 6-8 weeks during active growth
- Reduce or stop fertilizing in fall and winter
- Avoid over-fertilizing, which causes brown leaf tips and reduced blooming
Note: Peace Lilies are light feeders. Too much fertilizer does more harm than good!
Common Problems & Solutions
Brown Leaf Tips
Causes: Fluoride/chlorine in water, low humidity, over-fertilizing
Solution: Use filtered water, increase humidity, reduce fertilizer, trim brown tips with clean scissors
Yellow Leaves
Causes: Overwatering, poor drainage, or natural aging
Solution: Check soil moisture, ensure drainage holes exist, remove yellow leaves at the base
No Blooms
Causes: Insufficient light, young plant, or lack of fertilizer
Solution: Move to brighter indirect light, fertilize regularly during growing season, be patient with young plants
Drooping Leaves
Causes: Underwatering (most common), root rot from overwatering, or temperature stress
Solution: Water thoroughly if soil is dry, check roots for rot if soil is wet, maintain stable temperatures
Pests
Peace Lilies can attract spider mites, mealybugs, and scale. Treat with insecticidal soap or neem oil. Regularly wipe leaves with a damp cloth to prevent infestations and keep foliage glossy.
Encouraging Blooms
Peace Lily blooms are actually modified leaves called spathes that surround the true flower (spadix). To encourage more blooms:
- Provide bright, indirect light (the most important factor)
- Fertilize regularly during spring and summer
- Maintain consistent watering and humidity
- Remove spent blooms by cutting at the base
- Allow the plant to become slightly root-bound
Blooms typically last 1-2 months and gradually turn green before fading. This is normal!
Propagation
Propagate Peace Lilies through division:
- Remove the plant from its pot during repotting
- Gently separate crowns (clusters of leaves with roots attached)
- Ensure each division has at least 2-3 leaves and healthy roots
- Plant divisions in fresh potting mix
- Water thoroughly and keep in lower light until established
Spring is the best time for division when plants are actively growing.
Air Purifying Benefits
Peace Lilies are among NASA's top air-purifying plants, removing toxins like:
- Formaldehyde
- Benzene
- Trichloroethylene
- Ammonia
- Xylene and Toluene
They also increase humidity levels through transpiration, creating a healthier indoor environment. Explore our full collection of air-purifying plants or try our curated Air Purifying Plant Bundle.

Safety Note
⚠️ Important: All Peace Lily plants contain calcium oxalate crystals and are toxic to cats, dogs, and humans if ingested. Symptoms include mouth irritation, drooling, and difficulty swallowing. Keep out of reach of children and pets.
Final Tips for Success
- Wipe leaves monthly with a damp cloth to remove dust and improve photosynthesis
- Don't panic when your Peace Lily droops - it's just asking for water!
- Remove spent blooms and yellow leaves promptly to encourage new growth
- Rotate your plant weekly for even, balanced growth
- Peace Lilies can live for decades with proper care
- They're excellent "starter plants" for building confidence with houseplants
