Peace Lily Sunlight: Do They Need It and How Much?

Peace Lilies prefer bright, indirect light but can tolerate lower light conditions. Direct sunlight can cause the leaves to scorch and turn brown, so it’s best to place your Peace Lily in a spot where it will receive filtered or dappled light. If your Peace Lily is not producing flowers, it may need more light.

Peace Lily Soil Tips

Peace Lilies thrive in a well-draining, peat-based potting mix. A mix of one part peat moss and one part perlite is a good choice, as it will retain moisture without becoming waterlogged. Be sure to repot your Peace Lily every 1-2 years to refresh the soil and provide room for growth.

Peace Lily Watering and Frequency

Water your Peace Lily regularly to keep the soil evenly moist but not soggy. It’s essential to avoid overwatering, as this can lead to root rot. Peace Lilies are sensitive to chlorine and fluoride in tap water, so using filtered or rainwater is recommended. During the winter months, reduce your watering frequency, allowing the top inch of soil to dry out between waterings.

Pruning Peace Lilies Properly

Prune your Peace Lily regularly to remove dead leaves and spent flowers. This will encourage new growth and help maintain the plant’s appearance. Use clean, sharp scissors or pruning shears to make a clean cut close to the base of the leaf or flower stem.

Optimal Peace Lily Temperature: Can They Tolerate the Cold?

Peace Lilies prefer temperatures between 65-80°F (18-27°C) and do not tolerate cold drafts or temperatures below 45°F (7°C). Keep your Peace Lily away from drafty windows, air conditioning vents, and heaters to ensure a stable temperature and prevent stress on the plant.

Common Peace Lily Problems

Brown Leaf Tips

Brown leaf tips on Peace Lilies can be caused by several factors, such as underwatering, over-fertilization, or exposure to direct sunlight. To prevent this issue, ensure your watering and fertilization practices are appropriate for the plant’s needs and provide proper lighting conditions.

Yellow Leaves

Yellow leaves can be a sign of overwatering or poor drainage. To avoid this problem, ensure your pot has drainage holes and use a well-draining potting mix. Additionally, adjust your watering frequency to prevent soggy soil.


Peace Lilies can be susceptible to pests such as spider mites and mealybugs. Regularly inspect your plant for signs of pests, and treat any infestations promptly with insecticidal soap or neem oil.

Peace Lily Outdoors vs Indoors

Peace Lilies can be grown both indoors and outdoors, but they are primarily grown as indoor plantsdue to their preference for stable temperatures and indirect sunlight. Here’s a list of pros and cons for indoor and outdoor growth:

Location Pros Cons
  • Easier to control temperature and lighting conditions
  • Less exposure to pests and diseases
  • Air-purifying benefits for your living space
  • Requires more attention to watering and humidity
  • Potential for indoor pests
  • Can provide a natural, shaded environment for the plant
  • Easier to maintain humidity levels
  • More susceptible to temperature fluctuations and direct sunlight
  • Greater risk of pests and diseases

Best Pots for Peace Lilies

When choosing a pot for your Peace Lily, look for one with drainage holes to prevent waterlogging. Ceramic or terracotta pots are ideal, as they allow excess moisture to evaporate through the porous material. However, plastic pots can also be used if proper drainage is maintained. Select a pot that is slightly larger than the root ball of your plant, allowing room for growth. Repot your Peace Lily every 1-2 years to refresh the soil and provide additional space for the roots.
