Water regularly during the growing season, allowing the soil to dry out slightly between waterings. Reduce watering significantly in winter. Ensure good drainage to prevent root rot.

Overwatering is the most common cause of issues for Dierama species.

Remove spent flower stalks after blooming to maintain a tidy appearance and prevent self-seeding if undesired. Cut back dead foliage in late winter or early spring before new growth emerges.

Minimal pruning is generally required.

Propagate by division in early spring or by seed sown in autumn. Seed-sown plants may take several years to flower. Divisions should be replanted promptly into well-draining soil.

Repot established plants every 2-3 years in early spring, or when they become pot-bound. Use a free-draining, gritty compost. This species prefers to be slightly constricted in its pot.
