Water Wall germander moderately during its growing season, allowing the soil to dry out slightly between waterings. Reduce watering in winter to prevent waterlogged roots, which can lead to root rot.

Ensure good drainage to keep the plant healthy and thriving.

Prune Wall germander after flowering or in early spring to maintain its shape and encourage bushier growth. Deadhead spent flowers to promote further blooms.

Hard pruning can be done in late winter to rejuvenate older plants.

Propagate Wall germander from semi-hardwood cuttings taken in summer or from seed sown in autumn or spring. Cuttings root relatively easily in well-draining soil.

Seeds may require stratification before sowing for optimal germination.

Repot Wall germander every 2-3 years, or when root-bound, in spring. Use a well-draining potting mix, such as a combination of loam, sand, and peat. Ensure the new pot has drainage holes to prevent water accumulation.
