Meum athamanticum prefers consistently moist soil, especially during its active growth period. Water regularly to maintain even moisture, but avoid waterlogging, which can lead to root rot.

Reduce watering in late autumn and winter when the plant is dormant, allowing the soil to dry out slightly between waterings.

Pruning is primarily done to remove dead or damaged foliage and to maintain a tidy appearance. After flowering, you can deadhead spent flower stalks to prevent seed formation if desired.

In late winter or early spring, before new growth emerges, cut back any old, withered stems to the ground.

Meum athamanticum can be propagated by seed or by division. Sow seeds in autumn or early spring in a well-drained compost.

For division, carefully lift established clumps in early spring or autumn, and divide them into smaller sections, ensuring each section has healthy roots and shoots.

Repotting is usually only necessary for container-grown plants, or if the plant becomes root-bound. Perform this in early spring or autumn. Choose a pot that is slightly larger than the current one, with good drainage.

Use a well-draining, gritty compost mix to prevent waterlogging.
