🌱 How to Care for White Star Calathea to Prevent Mealybugs?

💧 How to Water

Water when the top 2 cm (about an inch) of soil feels dry to the touch, always using filtered water, rainwater, or tap water left uncovered overnight to let chlorine and fluoride evaporate. Never let the plant sit in standing water to avoid root rot.

☀️ Lighting

Provide bright indirect light for 8-10 hours a day, such as near an east- or north-facing window, or a bright spot filtered by a sheer curtain. Direct sun fades the leaf pattern and can scorch it; too little light causes slow growth and dull coloring.

🪴 Ideal Soil

Use a light, well-draining, organically rich mix — combine quality potting soil with coco coir or peat and perlite to retain moisture without waterlogging the roots.
