Victoria amazonica requires consistently high water levels. The plant must be grown in a pond or large container with at least 1 meter of water depth. Water should remain clean and free from debris.

Avoid water that is too shallow, as this can stress the plant and inhibit its growth.

Pruning is minimal. Remove any dead or decaying leaves and flower stalks as they appear to maintain water quality and plant health.

Large, old leaves can be carefully trimmed at the base if they become unwieldy or start to shade out younger foliage.

Propagation is typically done by seed or division. Seeds require stratification and specific conditions to germinate.

Division is more common for established plants, where rhizomes can be carefully separated and replanted in suitable aquatic soil.

Repotting is rarely needed for mature plants, as they are usually grown directly in pond bottoms or very large containers. If a plant outgrows its container or needs rejuvenation, repotting should occur in spring.

Use a large, sturdy container filled with heavy, nutrient-rich aquatic soil.
