Water regularly when the top few centimeters of soil are dry, especially during active growth and flowering. Reduce watering significantly during dormancy in winter.

Ensure good drainage to prevent root rot, as this plant prefers drier conditions once established.

Pruning is minimal for this plant. Remove dead or spent flower stalks after flowering to prevent self-seeding if desired. Wear gloves, as the plant has sharp spines.

No significant structural pruning is typically needed, as it has an upright habit.

Propagate from seed, sown in early spring or autumn. Seeds benefit from a period of cold stratification. Transplant seedlings carefully to avoid disturbing the taproot.

Division of established plants is rarely successful due to the strong taproot system.

Repotting is generally not necessary for established plants, as they are best grown in situ and dislike root disturbance.

If starting from seed or young plants, use well-draining soil and a pot that allows for the development of its taproot. Ensure pots have drainage holes.
