🌱 How to Care for Jewel Alocasia to Prevent Thrips?

💧 How to Water

Water when the top 2-3cm of soil feels dry, using room-temperature distilled or rainwater. Never let the pot sit in standing water - soggy soil is the fastest route to root rot in this species.

☀️ Lighting

Place in bright, indirect light such as an east- or west-facing window. Direct midday sun scorches the delicate leaves, while low light dulls their metallic sheen and slows growth.

🪴 Ideal Soil

Use a loose, well-draining aroid mix - equal parts peat or coco coir, perlite, and orchid bark - to keep roots aerated and prevent the waterlogging that leads to root rot.
