🌱 How to Care for Peace Lily to Prevent Mealybugs?

💧 How to Water

Water your Peace Lily when the top inch of soil feels dry, typically once a week. It is highly sensitive to overwatering — soggy soil leads to root rot. If leaves droop slightly, that is your plant telling you it needs water. Always use room-temperature water and ensure the pot drains freely after each watering.

☀️ Lighting

Peace Lilies thrive in bright indirect light, such as near an east- or north-facing window shielded from direct sun. They are among the few houseplants that tolerate low light, though flowering is best with more light. Direct sunlight will scorch the leaves, causing brown patches and yellowing.

🪴 Ideal Soil

Use a well-draining, organic-rich potting mix containing peat, perlite, and fine bark. The ideal pH is 5.5–6.5. Avoid dense, moisture-retaining soils that promote root rot. Repot every 2 years or when roots begin emerging from drainage holes.
