🌱 How to Care for Rose Painted Calathea to Prevent Leaf Spot?

💧 How to Water

Water approximately once a week, keeping the soil evenly moist but never soggy. Always use filtered, rain, or distilled water — tap water fluoride and chlorine cause brown leaf tips. Empty saucers after watering to prevent root rot.

☀️ Lighting

Place in bright, indirect light away from direct sunlight, which fades the beautiful leaf patterns. A north-facing window or a few feet back from an east/west window with a sheer curtain works perfectly.

🪴 Ideal Soil

Use a well-draining, peat-based or coco coir potting mix amended with perlite (2:1 ratio). Good drainage is essential to prevent root rot while retaining enough moisture. Target pH 5.5-7.0.
