Peace lilies are popular houseplants, prized for their lush foliage and beautiful flowers. However, it can be distressing and confusing to see a peace lily flower turning brown. Factors such as improper care, stress, and age can contribute to this issue. Throughout this article, we will explore the various reasons behind the browning of peace lily flowers and provide helpful solutions to ensure the health and success of your plant.

A peace lily flower turning brown is not an uncommon issue and should not necessarily be a cause for alarm. In many cases, it could simply be the natural aging process. All flowers have a lifespan, and it’s important to understand that it’s normal for them to change color and eventually die off as they mature. Nevertheless, it’s crucial to monitor your plant for other symptoms to verify that there are no underlying issues.

Aside from aging, environmental and care factors can play a significant role in peace lily flowers turning brown. Direct sunlight, inconsistent watering, and inadequate nutrients or humidity levels can all cause stress to the plant, leading to browning flowers. To better support your peace lily, keep reading as we delve into the specific causes and solutions that can help you maintain a thriving plant.

Possible Causes of Browning


One of the reasons a peace lily flower might turn brown is due to underwatering. When a peace lily doesn’t receive enough water, its leaves and flowers may begin to wilt and change color. To prevent this, make sure to regularly water your plant and monitor the moisture level in the soil.


On the other hand, overwatering can also cause browning in peace lily flowers. Excessive moisture in the soil can lead to root rot, which in turn affects the health of the entire plant, including its flowers. To avoid overwatering, follow a consistent watering schedule and allow the soil to dry out slightly between waterings.

Lack of Light

Peace lilies thrive in bright, indirect light. An inadequate light source may cause the flowers to lose their vibrant green color and eventually turn brown. To ensure your peace lily receives enough light, place it in a spot that gets bright but indirect light throughout the day.

Pests and Diseases

Pests and diseases can also lead to browning of your peace lily flowers. Common pests that may affect peace lilies include aphids, spider mites, and mealybugs. Meanwhile, diseases such as root rot and fungal infections can harm your plant as well. Keeping the plant clean, providing good airflow, and using appropriate pest control measures can help protect your peace lily from these threats.

  • To summarize, possible causes of browning in peace lily flowers include:
    • Underwatering
    • Overwatering
    • Lack of light
    • Pests and diseases

Proper Care for Peace Lily

Watering Schedule

To keep your peace lily healthy, it’s essential to maintain an appropriate watering schedule. Monitor the soil moisture and water the plant when the top inch becomes dry. Consistently moist soil is ideal, but avoid overwatering, as this can lead to root rot. Remember that while the peace lily can tolerate short periods of dryness, it prefers consistent moisture for optimal growth.

Sunlight and Location

The right amount of sunlight plays a significant role in the health of your peace lily. Ensure the plant receives bright, indirect sunlight rather than direct sunlight, which can cause the leaves and flowers to turn brown. Keep the plant away from direct sun exposure, and place it in a location where it can receive diffused, bright light.

Soil and Pot

The soil for your peace lily should be well-draining and nutrient-rich. A good potting mix would contain peat moss, perlite, and vermiculite. The pot in which the peace lily grows must have drainage holes at the bottom, as this helps prevent waterlogging and root rot. Repot the plant every couple of years to refresh the soil and provide room for growth.


Feeding the peace lily with the right nutrients is crucial to avoid browning of the flowers. Fertilize the plant every 6 to 8 weeks using a balanced liquid fertilizer diluted to half the recommended strength. Be cautious not to over-fertilize, as this can cause salts to build up in the soil and lead to the development of brown tips and flowers.

Reviving a Peace Lily with Brown Flowers

Trimming Brown Tips and Flowers

To revive a peace lily with brown flowers, start by gently trimming away any brown tips and flowers. Use clean, sharp scissors or pruning shears to remove the affected parts of the plant. Be careful not to cut into the healthy green portions of the leaves or flowers. Trimming away the brown parts will help the plant focus its energy on new growth and recovery.


Sometimes, a peace lily’s growth may be hindered by its pot and soil conditions. If you suspect this is the case, consider repotting your peace lily. Choose a pot that is slightly larger than the current one and has drainage holes to prevent standing water. Also, use fresh, well-draining soil that is specifically designed for indoor plants. Gently remove the peace lily from its current pot and carefully loosen the root ball. Place it in the new pot and fill with soil, ensuring the roots are fully covered. Water the plant thoroughly after repotting to help it settle in its new environment.

Restoring Water Balance

A common reason for peace lily flowers turning brown is water stress, which includes both overwatering and underwatering. To restore the water balance in your peace lily, take note of its moisture needs and adjust your watering schedule accordingly. Peace lilies prefer consistently moist soil, but not wet. To achieve this:

  • Use the “finger test” to check soil moisture: if the top inch of soil is dry, it’s time to water.
  • Water the plant deeply, allowing excess water to drain out of the pot.
  • Never allow the plant to sit in standing water, as this can cause root rot.

Additionally, ensure your peace lily is in a location with bright, indirect light and high humidity to further encourage healthy growth and prevent browning. You may also consider placing a tray of water or using a humidifier near the plant to increase humidity levels. By implementing these changes, you’ll be on your way to helping your peace lily recover from its brown flowers and regain its vibrant, healthy appearance.

Preventing Future Browning

To prevent future browning in peace lily flowers, it’s important to take proper care of the plant, considering aspects like proper watering, ideal lighting, and avoiding stress. There are a few key measures you can take to ensure the long-term health of your peace lily.

Watering Habits

Finding the right balance in watering your peace lily is crucial. Both over-watering and under-watering can cause brown tips on leaves and flowers. To maintain optimal moisture levels, water your plant when the top inch of soil feels dry. Avoid letting the plant sit in standing water. As a general rule, water less during winter and increase the frequency during warmer months.

Lighting and Location

Peace lilies prefer bright, indirect light. Direct sunlight can cause brown patches or browning tips on leaves and flowers. Find a spot for your peace lily near a window with natural light, but not in the path of direct sunlight. Alternatively, you can use blinds or other plants to shield your lily from harsh light.

Temperature and Humidity

Peace lilies thrive in moderate temperatures, between 65°F and 80°F (18°C to 26°C). Extreme temperatures or sudden fluctuations can cause browning. Keep your plant away from heating or cooling vents to avoid such stress. Additionally, maintain good humidity levels by misting the leaves or placing a humidity tray nearby.


Peace lilies require occasional fertilization. Over-fertilizing or under-fertilizing can cause browning. Fertilize your peace lily every 6 weeks during the growing season with a balanced, water-soluble fertilizer, ensuring to dilute it to half strength. Always water the peace lily after fertilizing to prevent root burn and remove excess salts.

By maintaining these essential aspects of peace lily care, you’ll help prevent browning in the future and keep your plant healthy and vibrant.
