Indoor flowers can bring life and beauty to any space, and one popular choice is the peace lily. With its elegant white flowers and ability to thrive in low light conditions, the peace lily (Spathiphyllum wallissii) is a favorite among plant enthusiasts.

However, like any plant, peace lilies can experience issues, such as brown or yellow leaves.

In this article, we will explore the reasons behind peace lily leaves turning brown or yellow, how to care for a peace lily, when it needs a new pot, and the right temperature for optimal growth.

Reasons Behind Peace Lily Leaves Turning Brown or Yellow

Peace lily plants typically have long, dark green leaves that emerge right from the soil. While these leaves are hardy, they can accumulate dust over time, leading to discoloration.

Additionally, improper watering can cause the edges of the leaves to turn yellow or brown. Overwatering or underwatering are common culprits for this issue.

To prevent mineral buildup, it is advisable to use filtered or bottled water when watering your peace lily. Tap water may contain minerals that can accumulate in the soil and affect the plant’s health.

Regularly wiping the leaves with a damp cloth can also help remove dust and keep them looking vibrant.

Treating Peace Lily Brown Leaves

Taking care of peace lily brown leaves is not as difficult as it may seem. By following a few simple steps, you can restore the health and beauty of your plant.

  1. Flush the peace lily plants with bottled water: Start by thoroughly flushing the plant with bottled water until there are no more drainage holes. This process helps to remove any mineral buildup and washes away excess minerals and salts that may be causing the leaves to turn brown or yellow.
  2. Regular watering: After flushing, continue watering your peace lily as usual. By using filtered or bottled water, you can ensure that the plant is receiving the right amount of hydration without the risk of mineral buildup. Trim any brown or yellowed parts of the leaves to promote new growth.

Caring for a Peace Lily and Potting Requirements

While peace lilies can tolerate crowding in their pots, they will eventually require repotting when their roots become overcrowded. It’s essential to check the roots periodically to determine when a new pot is needed.

Signs that your peace lily needs a new pot include roots growing through the drainage holes or sticking out of the soil surface.

If the plant is severely rootbound, it may struggle to absorb enough water, leading to withering even with regular watering.

When repotting your peace lily, follow these steps:

  1. Choose a bigger pot: Select a new pot that is at least two inches wider in diameter than the previous one. However, avoid choosing a pot that is excessively large, as this can lead to root rot. Cover the drainage hole with a coffee filter or a small piece of mesh to prevent soil from washing away.
  2. Add fresh potting mix: Fill the new container with fresh potting mix, ensuring that the top of the plant’s root ball sits ½ to 1 inch below the rim of the pot. Gently slide the plant out of the old pot and place it into the new one, making sure the roots are properly positioned.
  3. Settle the soil: Lightly water the soil to settle it around the roots, adding more soil if necessary to maintain the proper level. Place the peace lily in a shaded area until it recovers from the transplanting process.

The Right Temperature for Peace Lily

Maintaining the right temperature is crucial for the health and growth of peace lilies. These plants thrive in warm conditions and cannot tolerate temperatures below 40 degrees Fahrenheit.

It is important to avoid placing them near non-insulated windows or doors, especially during the winter months.

The ideal temperature range for peace lilies is between 65 – 80 degrees Fahrenheit (18 – 26 degrees Celsius). They also require a moderate level of humidity to thrive.

To increase humidity levels, you can place pebbles and water in the pot without overwatering the plant. Wait until the soil slightly dries out before watering again.


Caring for a peace lily and addressing issues like brown or yellow leaves is essential to keep these beautiful indoor plants healthy and thriving.

By understanding the reasons behind leaf discoloration, providing proper watering, repotting when necessary, and maintaining the right temperature, you can enjoy the beauty of peace lilies in your home or office environment.

Remember, these plants are not overly demanding and can reward you with their elegant flowers and lush foliage when properly cared for.
