Bupleurum acutifolium prefers consistently moist soil, but avoid waterlogging. Water thoroughly when the top inch of soil feels dry. Reduce watering during winter dormancy to prevent root rot.

Ensure good drainage to keep roots healthy.

Prune in late winter or early spring to shape the plant and remove any dead or damaged stems. Deadheading spent flowers throughout the blooming season can encourage further flowering.

Light trimming can maintain a tidy appearance.

Bupleurum acutifolium can be propagated from seeds sown in spring, either directly outdoors or started indoors a few weeks prior. Division of established clumps in spring is another effective method to increase your plant stock.

Repot young plants annually in spring. Mature plants can be repotted every 2-3 years, or when root-bound. Use a well-draining potting mix.

Choose a pot slightly larger than the current one to provide adequate space for root growth.
