🌱 How to Care for Domino Peace Lily to Prevent Pythium Root Rot?

💧 How to Water

Water when the top 2-3 cm of soil is dry, usually about once a week in the warm months and every 10-14 days in winter. Drooping means thirst; yellow leaves usually mean too much water. Filtered or rain water helps prevent brown tips caused by chlorine, fluoride and salts.

☀️ Lighting

Bright indirect light near an east or north window. In low light new leaves come out greener and flowering drops off; direct sun scorches the white areas.

🪴 Ideal Soil

Rich, moisture-retentive but well-draining mix: potting soil with fine bark, coco coir and perlite, in a pot with drainage holes.
