Spathiphyllum Care: How to Keep Your Peace Lily Healthy

Light Requirements

Spathiphyllum prefers bright, indirect light. Avoid direct sunlight, which can cause leaf burn. A spot near a north or east-facing window is usually suitable. If the plant receives too little light, flowering may decrease and growth can slow down.

Watering (with Concrete Checks)

Water your Spathiphyllum when the top 2-3 cm of soil feels dry to the touch. Insert your finger into the soil to check. In most homes, this means watering about once a week, but frequency depends on temperature, humidity and pot size. Reduce watering in winter. Always empty excess water from the saucer to prevent root rot.

Humidity

Spathiphyllum prefers moderate to high humidity. If the air is dry (especially in winter), mist the leaves occasionally or place the pot on a tray with pebbles and water (without letting the pot sit in water). Brown leaf tips may indicate low humidity.

Soil and Pot

Use a well-draining, peat-based potting mix. The pot should have drainage holes to prevent waterlogging. Repot every 2-3 years or when roots grow out of the bottom.

Feeding

Feed your Spathiphyllum with a balanced, water-soluble houseplant fertilizer at half strength every 6-8 weeks during spring and summer. Do not fertilize in winter.

Pruning and Removing Dead Leaves

Remove yellow or brown leaves by cutting them at the base with clean scissors. This helps prevent fungal issues and keeps the plant tidy. Spent flowers can also be trimmed off.

Repotting

Repot in spring if the plant becomes rootbound or growth slows. Choose a pot 2-4 cm wider than the current one. Gently loosen the root ball and refresh the soil.

Common Care Mistakes

• Overwatering: Always check soil moisture before watering.
• Direct sunlight: Can cause leaf scorch.
• Low humidity: Leads to brown leaf tips.
• Neglecting to remove dead leaves: May encourage disease.

Is Spathiphyllum Toxic to Pets?

Spathiphyllum contains compounds that may be toxic if ingested by cats, dogs, or other pets. Symptoms can include drooling, oral irritation, or vomiting. If you suspect your pet has eaten part of the plant, consult a veterinarian for advice.
