Keep the soil consistently moist but not waterlogged, especially during the growing season. Alocasia brisbanensis prefers regular watering, allowing the top inch of soil to dry out slightly between waterings.

Reduce watering in cooler months to prevent root rot. Ensure good drainage to avoid standing water.

Remove any yellowing, brown, or damaged leaves by cutting them at the base with clean, sharp shears. This not only improves the plant's appearance but also redirects energy to new growth.

Pruning can also be done to manage size or shape if desired.

Alocasia brisbanensis can be propagated by division of rhizomes or by carefully separating offsets (pups) from the base of the parent plant. Ensure each division has at least one leaf and a healthy root system.

Pot them in well-draining soil and maintain consistent moisture and warmth.

Repot Alocasia brisbanensis every 1-2 years, or when the plant becomes root-bound. Choose a pot that is one size larger than the current one.

Use a well-draining potting mix, such as a blend of peat moss, perlite, and compost. Repotting is best done in spring.
