Pastinaca kochii prefers consistent moisture but dislikes waterlogged conditions. Water deeply when the top 2-3 cm of soil feels dry.

Reduce watering in cooler months to prevent root rot, especially if grown in cooler climates or overwintering.

Pruning is generally minimal for Pastinaca kochii, primarily focused on removing spent flower stalks to prevent self-seeding if desired, or tidying up any dead or damaged foliage. Avoid heavy pruning as it disrupts its natural growth habit.

Pastinaca kochii can be propagated by seed, sown directly outdoors in early spring or autumn as it prefers cool conditions for germination. Alternatively, division of established clumps in early spring can also be successful.

Repotting is rarely necessary for Pastinaca kochii as it is typically grown as a perennial in garden beds. If grown in containers, repot only when root-bound, ideally in early spring before new growth begins.

Use well-draining soil.
