Alocasia are the divas of the aroid world. Those thick, upright, arrow-shaped leaves come with conditions attached: bright indirect light, warmth, humidity, and soil that drains fast but never dries out completely.
What every Alocasia wants
Nearly all of the ~90 species share the same baseline needs. Get these four right and the individual variety differences become minor tweaks:
- Bright indirect light. Direct midday sun scorches the leaves; deep shade makes them stretch and drop.
- Warmth, consistently. Below 15°C they sulk and often go dormant.
- Humidity above 60%. Crispy brown leaf edges are almost always this.
- Chunky, fast-draining mix. They grow from corms that rot in dense soil.
Dormancy is not death
The single most common Alocasia panic: every leaf dies back and the plant looks finished. In lower light and cooler temperatures Alocasia go dormant and retreat into the corm. Keep the soil barely damp, stop fertilising, and wait. New growth usually appears once conditions improve.
