🌱 How to Care for Voodoo Lily to Prevent Anthracnose?

💧 How to Water

Water when the top 2–3 cm of substrate has dried during the active growing period. Reduce significantly as dormancy approaches and stop entirely when foliage collapses. Never let the corm sit in waterlogged soil — tuber rot is the primary killer.

☀️ Lighting

Prefers bright indirect to dappled light. North- or east-facing windows are ideal indoors. Shield from intense afternoon sun, especially as new growth emerges in spring.

🪴 Ideal Soil

Use a rich, well-draining mix: compost (40%), perlite (30%), peat or coir (20%), coarse sand (10%). Maintain pH between 5.5 and 7.0. Good drainage is non-negotiable to prevent corm rot.
