Drought-tolerant once established. Water deeply but infrequently during the growing season, allowing the soil to dry out completely between waterings. Reduce watering significantly in autumn and cease almost entirely during winter dormancy to prevent rot. Overwatering is a common issue.

Pruning Showy Stonecrop is straightforward and primarily done for tidiness and to encourage bushier growth. In late autumn or early spring, cut back all spent flower stalks and any dead or damaged foliage to the ground. This 'chop and drop' method helps rejuvenate the plant. For a more compact form, new growth can be pinched back in late spring, which may also slightly delay flowering but results in a denser plant.

Easily propagated by stem cuttings in late spring or early summer. Allow cuttings to callus for a few days before planting in well-drained soil. Division of mature clumps in early spring is also very effective, ensuring each division has roots and shoots. Seeds can be sown, but germination can be slow.

For container-grown plants, repot every 2-3 years in early spring into a slightly larger pot with fresh, well-draining succulent or cactus mix. Ensure the new pot has adequate drainage holes. This provides fresh nutrients and prevents the plant from becoming root-bound, promoting healthier growth.
