Berula thunbergii thrives in consistently moist to wet conditions. Ensure the soil remains saturated, mimicking its natural aquatic habitat.

It is an excellent choice for pond edges, water gardens, or boggy areas where waterlogging is not a concern. Regular watering is crucial to prevent the plant from drying out.

Pruning is generally minimal for cutleaf waterparsnip. Remove any yellowing or dead foliage as needed to maintain a tidy appearance and prevent disease.

Trimming can also be done to control its spread in water gardens, though it is not typically aggressive.

Propagation is easily achieved through division of established clumps, best done in spring. The plant also readily self-seeds in suitable wet conditions.

Stem cuttings can also be taken and placed in water to root before transplanting.

Repotting is primarily done when propagating by division. For potted specimens, this would occur every 2-3 years in spring to refresh the soil and manage the plant's size.

Ensure the new pot has drainage holes if it's not intended for aquatic placement.
