🌿 Peace Lily: Why Its Leaves Are Turning Brown and How to Fix It, According to Experts

The peace lily (Spathiphyllum) is one of the most popular indoor plants, loved for its elegant white blooms and lush green foliage. But even the most low-maintenance plants can send out distress signals — and one of the most common is brown leaves.

🪴 1️⃣ The Most Common Reasons Peace Lily Leaves Turn Brown

1. Underwatering

Peace lilies are tropical plants that thrive in consistently moist soil — not soggy, but never bone-dry.
When deprived of water, the plant’s leaf tips dry out first, turning crispy and brown.

Fix it:

• Water your peace lily when the top inch of soil feels dry to the touch.

• Use room-temperature water, and make sure excess water drains freely.

2. Overwatering

On the flip side, too much water can cause root rot, leading to browning leaves that are soft or mushy.

Fix it:

• Make sure your pot has good drainage.

• Empty saucers after watering so roots don’t sit in water.

• If the roots smell foul or appear black, repot your plant in fresh, dry soil.

3. Low Humidity

Peace lilies love humidity — ideally around 50–60%. In dry indoor environments, especially during winter, the air can dehydrate the leaves, causing the edges to brown.

Fix it:

• Mist your plant regularly.

• Place it near a humidifier or on a pebble tray with water.

• Avoid positioning it near heaters or air conditioners.

4. Too Much Direct Sunlight

Despite their love for warmth, peace lilies prefer indirect light. Too much direct sunlight scorches the leaves, turning them brown or bleached.

Fix it:

• Move your plant to a bright spot with filtered light or partial shade.

• East-facing windows are ideal for gentle morning light.

5. Chemical Sensitivity (Tap Water or Fertilizer Burn)

Peace lilies are sensitive to chlorine, fluoride, and salts found in tap water or excess fertilizer. This often results in brown tips even if the plant otherwise looks healthy.

Fix it:

• Use filtered, distilled, or rainwater when possible.

• Feed with a balanced houseplant fertilizer once a month during spring and summer — but dilute it to half strength.

• Flush the soil occasionally with clean water to remove salt buildup.

🌿 2️⃣ How to Revive a Browning Peace Lily

1. Trim the damage: Use sterilized scissors to cut off brown or dead leaves. Trim just above the healthy green tissue.

2. Repot if needed: Replace old soil if it’s compacted or has poor drainage.

3. Adjust watering routine: Keep soil evenly moist, not soaked.

4. Increase humidity: Especially during dry months or if using indoor heating.

5. Wipe the leaves: Dust can clog pores, so gently clean them with a damp cloth.

• Rotate the pot every few weeks for even light exposure.

• Remove spent flowers to encourage new growth.

• Repot every 1–2 years to refresh nutrients and prevent root binding.
