Keep the soil consistently moist but not waterlogged. Allow the top 2-3 cm of soil to dry out slightly between waterings. Reduce watering frequency during the dormant winter months to prevent root rot.

Ensure good drainage to avoid standing water.

Remove any yellowing, brown, or dead leaves as they appear to maintain the plant's aesthetic appeal and direct energy to healthy growth. Trim back leggy stems if necessary to encourage a bushier habit.

Sterilize pruning tools before use to prevent disease spread.

Alocasia longiloba can be propagated through division of rhizomes during repotting. Carefully separate the plant into smaller sections, ensuring each piece has roots and at least one healthy leaf.

Pot the divisions in well-draining soil and keep them consistently moist.

Repot your Alocasia longiloba every 1-2 years, or when it becomes root-bound. Choose a pot that is only slightly larger than the current one. Use a well-draining potting mix rich in organic matter.

Repotting is best done in spring when active growth begins.
