Pimpinella acutidentata prefers consistently moist soil. Water thoroughly when the top 2-3 cm of soil feels dry. Avoid waterlogging, as this can lead to root rot.

During hot, dry periods, frequent watering may be necessary to maintain soil moisture.

Prune Pimpinella acutidentata to maintain shape and encourage bushier growth. After flowering, you can deadhead spent blooms to prevent seed formation and promote further flowering.

Trim back leggy stems to encourage a more compact form. Light pruning can be done anytime.

Pimpinella acutidentata can be propagated by seed sown in early spring, either directly outdoors or started indoors a few weeks prior. Division of established clumps in early spring is also an effective method.

Ensure new divisions have adequate moisture for establishment.

Repot Pimpinella acutidentata every 2-3 years or when the plant becomes root-bound. Spring is the ideal time for repotting, before new growth begins. Use a well-draining potting mix.

Choose a pot only slightly larger than the current one to avoid overwatering issues.
