🌱 How to Care for Rugose Alocasia to Prevent Thrips?

💧 How to Water

Check the top 4-5 cm of soil before watering; only water once it is dry. Water thoroughly until it drains from the pot, then never let the plant sit in standing water.

☀️ Lighting

Give it bright, indirect light such as a few feet back from an east- or south-facing window. Direct sun scorches the textured leaves; too little light causes leggy growth and pale color.

🪴 Ideal Soil

Pot in a chunky, well-draining aroid mix of orchid bark, perlite, and charcoal. Avoid dense, peat-heavy soil that holds too much moisture around the corm.
