Maintain consistently moist soil for Nymphaea heudelotii. The crown should be submerged by 10-30 cm of water. Avoid letting the soil dry out, especially during active growth.

Regular checks are essential to maintain ideal moisture levels for healthy development.

Prune Nymphaea heudelotii by removing any yellowing or decaying leaves and flower stalks at the base. This promotes new growth and maintains the plant's appearance.

Deadheading spent flowers also encourages further blooming. Use clean tools to prevent disease introduction.

Nymphaea heudelotii can be propagated by dividing established tubers in spring. Carefully separate sections of the rhizome, ensuring each piece has at least one growth bud.

Replant these divisions into suitable containers with aquatic soil.

Repot Nymphaea heudelotii every 2-3 years, or when the plant outgrows its container. This is best done in early spring before active growth begins.

Use a large, sturdy pot filled with heavy loam or specialized aquatic planting medium.
