Peace lilies (Spathiphyllum) are beloved houseplants, known for their lush green leaves and elegant white flowers. However, when they start showing signs of distress, it’s essential to identify the cause and take quick action. Here’s a guide to common problems and solutions:
—
1. Drooping Leaves
Causes:
Underwatering: Leaves droop due to lack of moisture.
Overwatering: Roots suffocate, leading to drooping foliage.
Temperature Stress: Exposure to temperatures outside the ideal range (65–80°F).
Fix:
Check the soil moisture. Water only when the top inch of soil is dry.
Ensure the pot has drainage holes to prevent waterlogging.
Keep the plant in a consistent temperature range, avoiding drafts or heat sources.

2. Yellowing Leaves
Causes:
Overwatering: Excess water can lead to root rot, causing leaves to yellow.
Nutrient Deficiency: Lack of essential nutrients like nitrogen or iron.
Natural Aging: Older leaves naturally turn yellow and die.
Fix:
Adjust your watering schedule and check for root rot. Remove the plant from its pot and trim any mushy roots.
Fertilize monthly with a balanced houseplant fertilizer during the growing season (spring and summer).
Remove yellowing leaves to encourage new growth.

3. Not Flowering
Causes:
Low Light: Insufficient light inhibits blooming.
Lack of Nutrients: Plants need extra nutrients to produce flowers.
Dormancy: Peace lilies have natural blooming cycles.
Fix:
Place the peace lily in a spot with bright, indirect light. Avoid direct sunlight, as it can scorch the leaves.
Use a phosphorus-rich fertilizer to promote flowering.
Be patient—flowers typically appear in late spring or summer.

4. Dying or Declining Plant
Causes:
Watering Issues: Both overwatering and underwatering are common culprits.
Pests: Spider mites, aphids, and mealybugs can weaken the plant.
Low Humidity: Peace lilies thrive in humid conditions.
Fix:
Establish a consistent watering routine. Avoid letting the soil dry out completely or become waterlogged.
Check for pests and treat with neem oil or insecticidal soap.
Increase humidity by:
Using a pebble tray with water.
Misting the leaves regularly.
Placing a humidifier nearby.

Additional Tips for Healthy Peace Lilies
1. Humidity:
Peace lilies prefer humidity levels above 50%. Group plants together to create a microclimate or invest in a humidifier.
2. Repotting:
If the plant is root-bound (roots circling the pot), repot it into a slightly larger pot with fresh, well-draining soil.
3. Clean Leaves:
Wipe leaves with a damp cloth to remove dust, which can hinder photosynthesis and attract pests.

Watch For These Warning Signs
Brown Tips:
Usually caused by dry air, inconsistent watering, or fluoride in tap water. Use filtered or distilled water to avoid fluoride toxicity.
Mushy Roots:
A sign of root rot. Remove the plant, trim affected roots, and repot into fresh soil with proper drainage.
