Maintain consistent moisture around the roots, ensuring the soil is always saturated but not waterlogged. For submerged plants, the water level should be sufficient to cover the rhizome and emerging leaves.

Avoid letting the soil dry out completely, especially during active growth.

Prune dead or yellowing leaves to maintain plant health and appearance. Remove spent flowers to encourage further blooming.

Trim any overgrown foliage that might be shading out other aquatic plants or obstructing pond aesthetics. Use clean, sharp tools for pruning.

Propagate primarily by division of rhizomes in early spring before new growth begins. Carefully separate healthy sections of the rhizome, ensuring each piece has at least one growing point.

Plant these divisions in pots with suitable soil and submerge them.

Repot water lilies every 1-2 years, preferably in spring. Choose a large, sturdy pot to accommodate root growth. Use a heavy, clay-rich soil mix without added fertilizers, as these can be added separately.

Ensure the pot has drainage holes before planting.
