Nymphaea candida thrives in consistently moist to waterlogged conditions. The rhizome should be submerged, with the water level typically 20-50 cm above the soil surface.

Ensure the pot is always submerged in water to prevent the soil from drying out, which can stress the plant.

Prune Nymphaea candida primarily to remove dead or yellowing leaves and spent flowers. Trim these back to the base of the plant to maintain aesthetic appeal and prevent rot.

This also encourages new growth and flowering throughout the season.

Propagation is most effectively done by dividing the rhizome in early spring. Carefully separate sections of the rhizome, ensuring each piece has at least one growing point.

Replant the divisions immediately in suitable aquatic soil and submerge them.

Repot Nymphaea candida every 2-3 years, or when the plant becomes pot-bound. This is best done in early spring before active growth begins.

Use a large, sturdy pot filled with heavy clay soil or a specialized aquatic potting mix.
