Water regularly, especially during establishment and dry periods. Allow the soil to dry slightly between waterings. Once established, it is quite drought-tolerant.

Overwatering can lead to root rot, so ensure good drainage.

Prune in late winter or early spring before new growth begins. Pruning can be done to shape the plant, remove dead or damaged wood, and encourage bushier growth. Hard pruning can rejuvenate older plants.

Deadheading spent flowers is not typically necessary.

Easily propagated from seeds sown in autumn or spring. Cuttings taken in mid-summer and treated with rooting hormone can also be successful. Stratification may improve germination rates for seeds.

Repotting is rarely necessary for established shrubs as they are long-lived and prefer not to be disturbed. If grown in a container, repot only when root-bound, typically every 3-5 years, into a slightly larger pot with fresh, well-draining soil.
