The peace lily (Spathiphyllum spp.) is a classic, elegant houseplant loved for its glossy green leaves and delicate white blooms. Known for its ability to thrive in low light and its air-purifying properties, the peace lily is both beautiful and functional. Despite its easy-going nature, a few specific care tips will ensure this plant remains healthy and vibrant in your home.
Peace lilies thrive in low to medium, indirect light, making them perfect for spaces with less sunlight. While they can tolerate low light, they flower more readily in brighter, indirect light conditions. Avoid direct sunlight, as it can scorch their leaves. If you want to encourage blooming, place your peace lily near a window with filtered light.
One of the peace lily’s most distinctive traits is its ability to tell you when it needs water—its leaves will droop dramatically when thirsty. To avoid stress, water your peace lily when the top inch of soil feels dry. Overwatering is a common issue, so ensure the pot has proper drainage and avoid letting the plant sit in standing water. During the growing season, water more frequently, and reduce watering in winter when growth slows. If watering into a pot without drainage holes, be sure to discard any excess sitting water to prevent root rot or pests.
Peace lilies prefer warm, humid environments. Ideal temperatures range from 65–85°F (18–29°C). Avoid exposing your plant to cold drafts or temperatures below 50°F (10°C). They thrive in humidity levels of 40–60%, so consider misting the leaves or using a humidifier, especially during dry months.
Peace lilies grow best in well-draining, nutrient-rich soil. A standard indoor potting mix works well, but you can add perlite or sand to improve drainage. Repot your peace lily every 1 to 2 years, or when notice it becoming root-bound. Choose a pot with drainage holes to prevent waterlogged roots.
Feed your peace lily with a balanced, water-soluble fertilizer once a month during the growing season (spring and summer). Too much fertilizer can cause brown tips on the leaves, so dilute the fertilizer to half strength and avoid overfeeding. Hold off on fertilizing during the fall and winter.
Regular maintenance keeps your peace lily looking its best. Remove yellowing or dying leaves with clean, sharp scissors. After blooms fade, trim the flower stems at the base to encourage new growth. Wipe the leaves with a damp cloth occasionally to remove dust and improve photosynthesis.
Peace lilies can be propagated by division. During repotting, carefully separate the plant into smaller sections, ensuring each division has its own roots and leaves. Plant each section in its own pot with fresh soil and water thoroughly.
Peace lilies are considered toxic to pets and humans if ingested. They contain calcium oxalate crystals, which can cause irritation to the mouth, throat, and stomach. Keep the plant out of reach of pets and children, and wash your hands after handling it.
