Bupleurum alpigenum prefers well-drained soil and can tolerate dry conditions once established. Water moderately when the top inch of soil feels dry, avoiding waterlogging which can lead to root rot.

Reduce watering significantly in winter.

Prune after flowering to maintain a tidy appearance and prevent excessive self-seeding if desired. Remove spent flower stalks to encourage further blooms or to prevent the plant from expending energy on seed production.

Light trimming can be done in early spring.

Bupleurum alpigenum can be propagated by seed sown in early spring, either directly outdoors or in a cold frame.

Division of established clumps in spring is another method, though this species may be sensitive to root disturbance. Handle with care.

As Bupleurum alpigenum generally prefers to be undisturbed, repotting is typically only necessary for container-grown specimens when they become root-bound, usually every 2-3 years. Repot in spring using a well-draining potting mix.
