Keep the substrate consistently moist, akin to a bog environment. For submerged plants, ensure the water level is stable. Avoid letting the soil or water completely dry out, as this species thrives in wet conditions.

Regular watering or maintaining a water feature is crucial for its health.

Pruning is primarily for aesthetic control and to encourage bushier growth. Trim back leggy stems to maintain a desired shape and density. Remove any yellowing or decaying leaves promptly to prevent disease.

Regular pinching of the tips will promote branching.

Creeping Primrose-Willow is easily propagated by stem cuttings. Simply take a healthy stem cutting, remove lower leaves, and place it in water or directly into moist substrate.

Roots will readily form, and new plants can be established quickly. Seeds can also be sown in moist soil.

Repotting is generally not a significant concern for this plant, as it often grows in water or very wet conditions.

If grown in a container, repotting may be needed every 1-2 years if it outgrows its space or the substrate becomes depleted. Use a rich, water-retentive potting mix.
