Root Rot

Overwatering

To address root rot, start by ceasing watering immediately and allow the soil to dry out. If the plant is severely affected, remove it from its pot, trim away any black, mushy roots, and repot in fresh, well-draining soil. Ensure the new pot has adequate drainage holes. Going forward, water only when the top inch of soil feels dry to the touch, and ensure the pot allows excess water to drain away freely.

Brown Leaf Tips

Underwatering

Peace lilies require consistent moisture to thrive, but they do not like to sit in waterlogged soil. To address brown leaf tips caused by underwatering, ensure you are watering your peace lily thoroughly as soon as the top inch of soil feels dry to the touch. Use room temperature water to avoid shocking the plant. If your home is particularly dry, consider increasing humidity around the plant with a pebble tray or humidifier. Regularly check the soil moisture and adjust your watering schedule as needed to maintain consistent soil moisture.

Spider Mite Infestation

Spider mites are tiny pests that thrive in warm, dry conditions. They feed on the sap of peace lilies, causing yellow or bronzed leaves and fine webbing on the plant.

To combat spider mites, first isolate the affected plant to prevent spread. Increase humidity around the peace lily, as spider mites prefer dry environments. Wash the plant gently with water to remove mites and webs. For severe infestations, use a miticide or neem oil, applying it according to the product's instructions. Regularly check the plant and repeat treatment if necessary. Maintaining a higher humidity level can prevent future infestations.

Fungal Leaf Spot

Caused by a variety of fungal pathogens, including those from the genera Cercospora and Phyllosticta, which thrive in moist conditions.

To manage fungal leaf spot, start by removing and destroying any affected leaves to prevent the spread of the fungus. Improve air circulation around your peace lily by spacing plants appropriately and avoiding overhead watering to keep the foliage dry. If the problem persists, applying a fungicide may be necessary. Choose a fungicide labeled for use on houseplants and follow the application instructions carefully. Preventive measures include maintaining a clean growing area and avoiding wetting the leaves when watering.
