🌱 How to Care for Earth Star to Prevent Scale Insects?

💧 How to Water

Water when the top of the soil feels dry, roughly once a week. Use filtered or rainwater, as the plant is sensitive to chlorine. Never let water pool in the central rosette to avoid rot.

☀️ Lighting

Prefers bright indirect light. Strong direct sun can scorch the leaves, while too little light causes the vibrant colors to fade. Best placed near a window with filtered light.

🪴 Ideal Soil

Use a well-draining, slightly acidic mix (pH 5.0-6.0). A bromeliad or orchid mix with pine bark, perlite, and charcoal works very well.
