🌱 How to Care for Monstera Thai Constellation to Prevent Sunburn (Sun Scorch)?

💧 How to Water

Water thoroughly when the top 5-7 cm of soil are dry, roughly every 7-10 days in the growing season and less often in winter. Use filtered, distilled, or rainwater when possible since this cultivar is sensitive to salts and minerals in tap water, and always let excess water drain away to avoid root rot.

☀️ Lighting

Place it a few feet from an east-facing window or in filtered light near a south/west window. Bright indirect light is essential to keep the white sections vivid; too little light causes reversion toward solid green, while direct sun scorches the chlorophyll-poor white patches, which cannot dissipate heat as efficiently as green tissue.

🪴 Ideal Soil

Pot in a chunky, aroid-style mix, such as potting soil combined with orchid bark, perlite, and charcoal or coco coir in roughly equal parts, to guarantee fast drainage and airflow around the roots. This cultivar is more sensitive to soggy soil and root rot than the plain-green species.
