Cup Plant prefers consistently moist soil, especially when young. Water deeply once a week during dry spells, reducing frequency as plants establish. Avoid waterlogged conditions, which can lead to root rot.

Allow the top few centimeters of soil to dry out slightly between waterings.

Pruning is usually minimal. Deadhead spent flowers to encourage a tidier appearance and potentially a second bloom. Cut back foliage to the ground in late winter or early spring before new growth emerges.

Some gardeners leave the dried seed heads for winter interest and wildlife.

Cup Plant can be propagated by seed sown in fall or early spring, or by division of established clumps in early spring. Seeds may require a period of cold stratification.

Divisions should be replanted promptly and watered well to encourage establishment.

Repotting is typically only necessary for container-grown plants, which may need repotting every 2-3 years to refresh the soil and accommodate root growth. Spring is the ideal time for repotting.

Choose a pot that is slightly larger than the current one.
