Keep the soil consistently moist during the growing season, but avoid waterlogging. Reduce watering significantly as the foliage begins to yellow and die back in late summer or autumn.

Ensure good drainage to prevent root rot.

Remove spent flower stalks and yellowing leaves promptly to encourage further blooming and maintain a tidy appearance.

After flowering, allow the foliage to naturally die back as the plant prepares for its dormant period. Cut back dead foliage in autumn.

Zantedeschia elliottiana can be propagated by dividing the rhizomes in early spring before new growth begins. Ensure each division has at least one growth bud.

Alternatively, seeds can be sown in spring, but this is a slower method and may not produce true-to-type plants.

Repot rhizomes or established plants every 2-3 years in early spring. Use a well-draining potting mix, such as a blend of peat moss, sand, and compost.

Choose a pot that is slightly larger than the previous one to accommodate root growth.
