Peace lilies are popular houseplants known for their elegant green foliage and beautiful white flowers. However, many people encounter a common issue with this plant – its leaves turning brown. This can be concerning, especially if you’re unsure of the cause or solution. There’s no need to worry though, as many factors can contribute to this issue and understanding these causes can help you take proper care of your peace lily.

One of the reasons your peace lily’s leaves may be turning brown is improper lighting. These plants prefer indirect sunlight and can suffer from leaf burn when exposed to direct sunlight for even a few hours. Another possible cause is inadequate watering, as both overwatering and underwatering can lead to brown leaves. Finding the right balance is essential to maintain the health of your peace lily.

Aside from lighting and watering, other factors could cause peace lily leaves to turn brown, such as low humidity, temperature stress, and nutrient deficiencies. Exploring these reasons and applying suitable solutions can significantly improve the condition of your peace lily, ensuring vibrant and healthy growth for a beautiful indoor plant.

Causes of Brown Leaves on Peace Lilies


One common reason for brown leaves on peace lilies is underwatering. When the plant receives too little water, the leaf tips may turn brown. To prevent this, it’s essential to water your peace lily when the soil dries out or when the plant wilts slightly.


On the other hand, overwatering can also cause brown leaves on peace lilies. If the roots remain in standing water, it can lead to root rot, which is detrimental to the plant’s health. Overwatering can also cause leaves to turn brown due to the lack of oxygen and nutrients reaching the leaves.

Low Humidity

Peace lilies originate from tropical areas which means they prefer high humidity levels. Low humidity can cause the leaf tips to brown due to the increased rate of moisture loss from plant tissues. To increase humidity for your peace lily, you can:

  • Place the plant on a tray filled with water and pebbles
  • Use a humidifier near the plant
  • Mist the leaves regularly with water

Chlorine in Water

Chlorine, commonly found in tap water, can harm sensitive plants like peace lilies. When you water your peace lily with tap water, the chlorine can cause the leaf tips to turn brown. To avoid this issue, you can:

  • Allow tap water to sit out for 24 hours before watering to let the chlorine dissipate
  • Use filtered or distilled water for watering your peace lily

By monitoring your peace lily’s water intake, humidity, and the type of water you use, you can help prevent brown leaves and promote the overall health of your beautiful plant.

Signs and Symptoms

Leaf Tips Turning Brown

One of the initial symptoms indicating that something is wrong with your peace lily is when the leaf tips start turning brown. This could be due to several factors, including improper watering, temperature stress, and exposure to direct sunlight. To prevent this issue, ensure that your peace lily receives adequate indirect light and maintain a consistent watering schedule to keep the soil evenly moist.

Entire Leaf Browning

If you notice the entire leaves of your peace lily turning brown, this could be a sign of a more serious problem such as disease or infestation. Common diseases that affect peace lilies include bacterial blight, fungal leaf spot, and root rot. To prevent the spread of disease, it’s crucial to appropriately diagnose the underlying issue and take appropriate measures to treat it. This may involve removing affected leaves and improving overall plant care practices.

Yellowing Leaves

Yellowing leaves can also be an indication of improper care for your peace lily. Potential causes of yellow leaves include:

  • Overwatering or underwatering: Peace lilies prefer evenly moist soil, so it’s essential to establish a consistent watering routine.
  • Poor water quality: Peace lilies are sensitive to low-quality water, which can cause leaves to yellow. Consider using filtered or distilled water for your plant.
  • Insufficient light: Peace lilies thrive in bright, indirect light. Ensure your plant is placed in an area with adequate light conditions.

By addressing these issues and carefully monitoring your peace lily, you can maintain healthy foliage and prevent further problems from arising.

Preventing and Treating Brown Leaves

Proper Watering Techniques

To prevent and treat brown leaves on your peace lily, proper watering techniques are essential. Peace lilies are sensitive to water changes, so it’s crucial to allow the soil to dry out between waterings. Overwatering can cause the entire leaf to turn brown, while underwatering can lead to browning leaf tips. To properly water your peace lily, check the soil’s moisture and only water when necessary. Make sure the pot has drainage holes to prevent waterlogging, which can lead to root rot.

Increasing Humidity

Peace lilies thrive in environments with 60% humidity. Low humidity can cause leaves to wilt, dry out, and turn brown. You can increase the humidity around your peace lily by following these tips:

  • Place a tray of water near the plant to increase humidity as the water evaporates
  • Group your peace lily with other plants, as they will naturally raise the humidity around them
  • Use a humidifier in the room where your peace lily is located
  • Mist the leaves regularly with a spray bottle filled with lukewarm water

Using Filtered Water

Peace lilies can be sensitive to the chemicals in tap water, such as chlorine and fluorine, which can contribute to brown leaves or leaf tips. Using filtered water can help prevent these issues. If using tap water, let it sit for 24 hours before using it to water your peace lily, which allows most of the chlorine to evaporate.

In conclusion, proper watering techniques, increasing humidity, and using filtered water are essential steps in preventing and treating brown leaves on your peace lily. By carefully maintaining these aspects of your peace lily’s care, you can help ensure the health and beauty of your plant.


In summary, there are several factors that can cause Peace Lily leaves to turn brown, and understanding these factors can help you prevent and fix the issue. Some of the main reasons for the browning of leaves include improper amounts of light, water, fertilizer, humidity, low-quality water, and incorrect temperature.

  • Make sure your Peace Lily receives appropriate amounts of indirect sunlight and avoid exposing it to direct sun as this can cause browning in patches or at the tips of the leaves.
  • Make adjustments to your watering schedule and be mindful of both overwatering and underwatering. Give your plant enough water to keep the soil moist while allowing it time to dry out between waterings.
  • Monitor the humidity levels around your Peace Lily, as low humidity can lead to leaves turning brown and dropping off. Aim for around 60% humidity for optimal growth.
  • Be cautious with the use of fertilizers, and avoid using too much or too little, as this can lead to brown leaves.
  • Avoid using low-quality water or water that contains high levels of contaminants, as this can negatively affect the overall health of your Peace Lily.
  • Lastly, maintain a comfortable temperature for your plant, avoiding extremes that can cause stress and leaf browning.

By addressing each of these factors and applying the appropriate measures, you can help ensure that your Peace Lily stays healthy, vibrant, and free from brown leaves. Remember, it is essential to monitor your plant’s health and react accordingly to any changes in its appearance or growth. Happy gardening!
