Water Herbertia crosae moderately during the growing season, allowing the soil to dry out slightly between waterings. Reduce watering significantly in winter to prevent root rot, especially if grown in cooler conditions.

Ensure good drainage to avoid waterlogged soil.

Prune Herbertia crosae after flowering to remove spent flower stalks and any dead or damaged foliage. This encourages a tidy appearance and can help redirect the plant's energy.

Light pruning can also be done in early spring before new growth begins.

Propagation of Herbertia crosae is typically done by division of tubers in spring or by seed. Sow seeds in well-draining soil and keep moist.

Division is a more reliable method for established plants, ensuring genetic continuity and faster flowering.

Repot Herbertia crosae every two to three years or when the pot becomes crowded. Use a well-draining potting mix, such as a cactus or succulent blend.

Spring is the ideal time to repot, just as new growth begins, to minimize stress.
