Water regularly during the growing season, allowing the soil to dry slightly between waterings. Reduce watering in winter to prevent waterlogging.

Ensure good drainage to avoid root rot, as Erica arborea dislikes consistently wet feet. Monitor soil moisture to prevent both over and underwatering.

Prune immediately after flowering to maintain shape and encourage bushier growth. Remove any dead, damaged, or crossing branches. For larger specimens, light formative pruning can be done in spring.

Avoid hard pruning into old wood, as it may not recover well.

Propagate from semi-hardwood cuttings taken in late summer or early autumn. Insert cuttings into a well-draining, sandy, peat-based compost and keep them in a propagator or covered to maintain high humidity.

Rooting can take several weeks to months.

Repot young plants annually or every two years in spring, moving them into a pot only slightly larger. Mature plants can be repotted every 3-4 years.

Use a well-draining, acidic compost mix, similar to that used for rhododendrons or azaleas. Ensure the new pot has adequate drainage holes.
