🌱 How to Care for West Indian Tufted Airplant to Prevent Southern Blight?

💧 How to Water

Fill and flush the central rosette cup with water regularly, letting it dry out briefly between refills, and water the potting mix only when the top layer feels dry to prevent root rot.

☀️ Lighting

Provide bright, indirect light for around 12 hours a day; direct sun can scorch the leaves, while too little light will delay or prevent flowering.

🪴 Ideal Soil

Grow in a light, fast-draining epiphyte mix of bark, peat, and perlite rather than dense garden soil, since the roots need excellent airflow and cannot tolerate standing water.
