Water regularly, keeping the soil consistently moist but not waterlogged, especially during active growth. Reduce watering in cooler months when the plant is less vigorous.

Ensure good drainage to prevent root rot, as Calystegia hederacea prefers damp conditions.

Prune in late winter or early spring to remove any dead or damaged stems and to control the plant's size and spread. Pinch back young shoots to encourage bushier growth. Regular deadheading can promote further blooming.

Calystegia hederacea can be propagated by seeds sown in spring or by division of established clumps. Softwood cuttings can also be taken in late spring or early summer and rooted in moist soil or water.

Repot young plants annually or as needed into slightly larger containers. Mature plants can be divided and repotted every 2-3 years in spring.

Ensure the new pot has good drainage holes and use a well-draining potting mix.
