Alocasia: light, humidity and seasonal growth

Alocasia × amazonica. Its large leaves react to cold, dry air and wet roots, so stable conditions matter more than frequent adjustments.

Alocasia

Light

Plenty of indirect light without harsh midday sun.

Watering

Keep the mix moderately moist but let the surface dry slightly.

Soil

An airy mix that holds some moisture without becoming waterlogged.

Care over time

Rhythm through the year

In lower light, Alocasia may slow down or lose an older leaf. Match watering to the actual drying rate.

Growth and repotting

Repot during active growth once roots fill the container. Avoid moving it into a pot much larger than the root ball.
