Great waterleaf prefers consistently moist soil, especially during its active growing season. Water thoroughly when the top inch of soil feels dry. Avoid waterlogging, as this can lead to root rot.

Reduce watering in the fall as the plant begins to go dormant, allowing the soil to dry out more between waterings.

Pruning is generally not required for great waterleaf, as it naturally forms an attractive clump. Dead or damaged foliage can be removed at any time to maintain tidiness.

If the plant becomes too large or leggy, you can cut it back in late spring or early summer to encourage bushier growth.

Great waterleaf can be propagated by division of established clumps in early spring or fall. Carefully dig up the plant, separate sections with healthy roots and shoots, and replant them immediately.

It can also be grown from seed, sown outdoors in the fall or stratified indoors.

Repotting is primarily for division or if the plant becomes root-bound in a container. This is best done in early spring before new growth begins.

Choose a pot that is slightly larger than the current one, ensuring it has adequate drainage holes. Use a well-draining potting mix.
