How to Grow Peace Lily Plant Indoors

Updated: June 28, 2023

Peace lilies, scientifically known as Spathiphyllum, are popular indoor plants that are loved for their beautiful foliage and elegant white flowers. Not only do they add a touch of serenity to any space, but they also help purify the air by removing toxins. If you are looking to bring some greenery into your home or office, here is a comprehensive guide on how to successfully grow peace lily plants indoors.

Choosing the Right Location

When it comes to growing peace lilies indoors, finding the right location is crucial for their overall health and growth. These plants prefer bright, indirect light, so it’s best to place them near a north or east-facing window. Avoid exposing them to direct sunlight as this can lead to scorched leaves.

Temperature and Humidity

Peace lilies thrive in temperatures between 65-85°F (18-29°C). They are tropical plants, so it’s essential to keep them away from drafts or cold air-conditioning vents. Maintaining a consistent temperature will promote healthy growth.

In terms of humidity, peace lilies enjoy higher levels of moisture in the air. If the air in your home is dry, you can increase humidity by placing the plant on a tray filled with water and pebbles. Be sure not to let the pot sit directly in the water as this can lead to root rot.

Watering and Soil

Proper watering is key to maintaining a healthy peace lily plant. It’s important not to over-water or allow the roots to sit in water for extended periods as this can cause root rot. On the other hand, underwatering can lead to wilting and stunted growth.

To determine when it’s time to water, check the top inch of soil. If it feels dry, it’s time to water. Use room temperature water and pour it into the pot until it drains out of the bottom. Empty the saucer so that the roots are not sitting in water.

When it comes to soil, peace lilies prefer a well-draining potting mix. Look for a soil mix that retains moisture without becoming waterlogged. Adding perlite or sand can help improve drainage.

Fertilizing

Peace lilies benefit from regular feeding to promote healthy growth and vibrant flowers. During the growing season (spring and summer), use a balanced, water-soluble fertilizer diluted to half strength. Apply the fertilizer every six to eight weeks. Be sure to follow the instructions on the packaging for proper application.

Pruning and Propagation

Pruning your peace lily plant is essential for maintaining its shape and encouraging new growth. Remove any yellow or brown leaves by cutting them off at the base of the stem. If your plant becomes too large, you can also trim back some of the stems to control its size.

Propagation is another way to expand your peace lily collection or share plants with friends and family. The easiest method is through division, which involves separating the plant into smaller sections. Carefully remove the plant from its pot and gently separate the root clumps. Ensure each division has several stems and healthy roots before replanting them in their individual pots.

Common Issues and Troubleshooting

Even with proper care, peace lilies may encounter a few common issues. Here are some troubleshooting tips:

  • Yellow leaves: This can be a sign of overwatering, underwatering, or exposure to direct sunlight. Adjust your watering schedule and move the plant away from direct light.
  • Brown tips: Dry air or inconsistent watering can cause brown tips on peace lily leaves. Increase humidity levels or adjust your watering routine accordingly.
  • Failure to bloom: Peace lilies generally bloom when they receive adequate light and proper care. Ensure they are getting enough indirect light and follow a regular fertilizing routine.

Conclusion

Growing peace lily plants indoors can be a rewarding and enjoyable experience. With the right amount of light, proper watering, and attention to humidity levels, you can successfully cultivate these beautiful plants in your home or office. Remember to provide regular fertilization, prune as needed, and troubleshoot any issues that may arise. Soon enough, you’ll be rewarded with lush foliage and elegant white flowers that bring a sense of peace and serenity to your space.
