The peace lily (Spathiphyllum) is a popular indoor plant known for its attractive dark green leaves and striking white flowers. However, it can be concerning when the beautiful white blooms start turning brown. In this article, we will explore the possible causes behind brown peace lily flowers and provide helpful tips to address this issue and revive the plant’s vibrant appearance.

Understanding the Causes

1. Overwatering or Underwatering

Inadequate watering is among one of the most common reasons of brown peace lily blossoms. Overwatering can cause root rot, which may damage the plant and cause the blossoms to turn brown. On the other side, underwatering may give rise to withering and dryness, which additionally makes the flowers droop and lose their colour.

2. Inadequate Light Levels

Peace lilies thrive in bright, indirect light. Insufficient light can weaken the plant, leading to brown flowers. Placing the peace lily in a dimly lit area or away from windows can hinder its ability to photosynthesize and maintain healthy blooms.

3. Temperature Extremes

Peace lilies prefer moderate temperatures ranging from 65°F to 80°F (18°C to 27°C). Exposure to extreme cold or hot temperatures can stress the plant and cause its flowers to turn brown.

4. Low Humidity

Peace lilies are tropical plants that appreciate high humidity levels. Dry air can lead to browning of the flowers and leaves. This is especially common in indoor environments with central heating or air conditioning systems that reduce humidity.

5. Fertilizer Issues

Using the wrong type or excessive amounts of fertilizer can negatively impact the peace lily’s health. Too much fertilizer can burn the roots and result in brown flowers, while insufficient or incorrect nutrients can lead to deficiencies and discoloration.

Addressing Brown Peace Lily Flowers

1. Adjust Watering Practices

Ensure that you are watering your peace lily properly. Stick your finger about an inch into the soil, and if it feels dry, it’s time to water. However, if it feels moist, hold off on watering. Always use well-draining soil and pots with drainage holes to prevent waterlogged roots.

2. Provide Adequate Light

Place your peace lily in a well-lit area, away from direct sunlight. Indirect, bright light is ideal for healthy growth and vibrant flowers. Consider moving the plant closer to a window or providing artificial light if natural light is limited.

3. Maintain Optimal Temperature and Humidity

Keep your peace lily in a temperature-controlled environment within its preferred range. Avoid exposing it to drafts or extreme temperature fluctuations. Increase humidity around the plant by misting the leaves with water or placing a tray filled with water and pebbles nearby.

4. Follow Proper Fertilizer Guidelines

Use a balanced, water-soluble fertilizer formulated specifically for houseplants. Follow the package instructions for application rates and frequency. Generally, it’s recommended to fertilize peace lilies every 2-4 weeks during the growing season, reducing frequency in winter.

5. Prune and Remove Brown Flowers

Trim away any brown or wilted flowers using clean, sharp scissors or pruning shears. This not only improves the plant’s appearance but also directs its energy towards producing new healthy blooms.


Brown peace lily flowers can be a sign of underlying issues that need attention. By understanding the causes and implementing the appropriate remedies, you can restore your peace lily to its full glory. Remember to adjust your watering routine, provide adequate light, maintain suitable temperature and humidity levels, use proper fertilization techniques, and prune as needed. With proper care, your peace lily will reward you with beautiful, vibrant blooms once again.
