Care Tips

Southernwood prefers well-drained soil and a sunny location, making it an ideal candidate for drought-tolerant gardens. It thrives in full sun exposure, requiring at least 6 hours of sunlight daily. Watering should be moderate; the soil should be allowed to dry out between watering sessions to prevent root rot. Fertilization is not typically necessary, but a balanced, all-purpose fertilizer can be applied in early spring to encourage growth. Pruning is recommended to maintain the plant’s shape and to promote bushiness; cutting back the stems by about one-third in spring helps rejuvenate the foliage. Pest issues are rare, but watch for aphids and spider mites; they can be managed with insecticidal soap. Southernwood is relatively hardy and can tolerate poor soil conditions, making it low-maintenance.

Propagation Methods

Southernwood can be propagated through seeds or cuttings. For seeds, sow in early spring, either directly in the garden or in trays with seed-starting mix, lightly covering them as light aids germination; keep soil consistently moist. Germination should occur within 2-3 weeks at a temperature of 18-20°C (65-68°F). Alternatively, cuttings can be taken from healthy stems in the early summer, approximately 4-6 inches long, with the lower leaves stripped off. Dust cut ends with rooting hormone, plant in a mix of perlite and peat, and keep moist until roots develop (usually within 4-6 weeks). Success rates for cuttings are about 70-80% under optimal conditions.
