🌱 How to Care for Thai Beauty Calathea to Prevent Mealybugs?

💧 How to Water

Water every 7 days, or when the top 2-3 cm of soil feels slightly dry. Always use filtered, rain, or tap water left to sit for 24 hours to remove fluoride and chlorine, which cause brown leaf tips. Reduce watering frequency in winter.

☀️ Lighting

Place within 1 meter of a bright, east- or west-facing window receiving indirect light. Avoid direct sunlight, which fades and scorches the distinctive leaf patterns. In low-light conditions, growth slows and leaf colors become less vivid.

🪴 Ideal Soil

Use a light, well-draining mix: 2 parts peat or coconut coir with 1 part perlite or coarse sand. Target pH between 6.0 and 6.5. Always use pots with drainage holes to prevent root rot.
