Essential Tips for Peace Lily Maintenance

Updated: Jun 4

Peace lilies (Spathiphyllum) are beloved for their lush, green foliage and elegant white flowers, making them a popular choice for indoor plants. Not only are they beautiful, but they are also relatively low-maintenance, making them perfect for both novice and experienced plant enthusiasts. To help you keep your peace lily thriving, here are some essential maintenance tips.

Light Requirements

Indirect Light is Best: Peace lilies flourish in bright, indirect light. While they can tolerate low light conditions, they may not flower as frequently. Direct sunlight, on the other hand, can scorch their delicate leaves, so it's best to keep them in a spot with filtered light.

Artificial Light Works Too: If your home or office has limited natural light, don't worry! Peace lilies can also do well under fluorescent lights, making them a versatile option for various indoor environments.

Consistent Moisture: One of the key aspects of peace lily care is maintaining consistent soil moisture. Water your peace lily when the top inch of soil feels dry to the touch. They enjoy a consistently moist environment but be cautious not to overwater, as this can lead to root rot.

Proper Drainage is Crucial: Ensure your pot has drainage holes to allow excess water to escape. Sitting in water can be detrimental to your peace lily's health.

Humidity Needs

High Humidity Preference: Peace lilies thrive in higher humidity environments. To increase humidity, consider misting the leaves regularly, placing the pot on a tray filled with water and pebbles, or using a humidifier. This mimics their natural tropical habitat and keeps the foliage lush.

Avoid Dry Air: Keep your peace lily away from drafts, air conditioning vents, and radiators, as dry air can cause the leaf tips to turn brown.

Moderate Temperature Range: Peace lilies prefer temperatures between 65-85°F (18-29°C). They are sensitive to cold, so avoid exposing them to temperatures below 45°F (7°C) or sudden temperature changes.

Soil and Fertilization

Well-Draining Soil: Use a high-quality potting mix that drains well. A mix designed for houseplants, or one containing peat moss, perlite, and pine bark, is ideal for peace lilies.

Regular Feeding: Fertilize your peace lily with a balanced, water-soluble fertilizer every 6-8 weeks during the growing season (spring and summer). Reduce feeding during the fall and winter months when the plant's growth slows down.

Pruning and Cleaning

Trim Dead Leaves: Regularly remove any yellow or brown leaves at the base to keep your plant healthy and looking its best. This helps prevent disease and encourages new growth.

Dust the Leaves: Dust can accumulate on the leaves, blocking light and reducing photosynthesis. Wipe the leaves with a damp cloth periodically to keep them clean and shiny.


Repot When Necessary: Peace lilies generally need repotting every 1-2 years. If you notice roots growing out of the drainage holes or the plant becomes root-bound, it's time to move it to a slightly larger pot with fresh soil.

Pest Control

Monitor for Pests: Check your peace lily regularly for common houseplant pests like spider mites, aphids, and mealybugs. If you notice any, treat the plant promptly with insecticidal soap or neem oil to prevent infestations from spreading.

Flower Care

Encourage Blooms: To encourage flowering, ensure your peace lily gets adequate light and is not over-fertilized. They typically bloom in spring and early summer, producing beautiful white spathes.

Remove Spent Flowers: Once a flower has faded, cut it off at the base. This helps the plant conserve energy and encourages more blooms in the future.


With these essential maintenance tips, you can enjoy a healthy, vibrant peace lily that adds a touch of elegance to your indoor space. Remember, consistency is key regular watering, appropriate light, and attention to humidity and temperature will keep your peace lily flourishing for years to come. Happy gardening!
