Water sparingly, allowing the soil to dry out completely between waterings. Teucrium marum is drought-tolerant and susceptible to root rot if overwatered.

In winter, reduce watering significantly to mimic its natural dormancy period and prevent waterlogged conditions.

Prune after flowering in late summer or early autumn to maintain a compact shape and encourage bushier growth. Remove any dead, damaged, or crossing stems.

Light annual pruning is sufficient; avoid heavy cutting back into old wood.

Propagate from semi-hardwood cuttings taken in late summer. Insert cuttings into a well-draining, sandy compost and keep them in a propagator or covered with a plastic bag in a bright, warm location.

Roots usually form within 4-6 weeks.

Repot Teucrium marum every 2-3 years, or when the plant becomes root-bound. Use a free-draining compost mix, such as a blend of potting soil and perlite or grit. Repot in spring before new growth begins.
