Water regularly during the growing season, keeping the soil consistently moist but not waterlogged. Allow the top inch of soil to dry out slightly between waterings.

Reduce watering in autumn and winter to prevent root rot. Ensure good drainage to avoid standing water.

Pruning is typically minimal. Deadhead spent flowers to encourage further blooming and maintain a tidy appearance.

If the plant becomes leggy, you can trim it back in late spring or early summer to promote bushier growth. Remove any dead or damaged foliage as needed.

Lysimachia foemina is easily grown from seed, which can be sown directly outdoors in spring after the last frost or started indoors a few weeks prior.

It can also be propagated by division of established clumps in early spring. Cuttings can also be taken in late spring.

This plant is often treated as an annual or self-seeds readily. If grown in pots and it becomes root-bound, repot in spring to a slightly larger container. Ensure the new pot has adequate drainage holes.

Use a well-draining potting mix.
