How to Grow Southernwood
Artemisia abrotanum
Plant in full sun and poor to average, well-drained soil — southernwood dislikes rich soil. Water until established, then leave it largely alone. Cut hard to 10–15 cm from the base each spring before new growth gets going; this is the single most important task. The aromatic grey-green foliage is the main attraction; flowering is rare in cool climates. Tuck a few sprigs in drawers or wardrobes as a natural moth repellent.
Yearly Lifecycle
Care Essentials
Not needed on poor, free-draining soil. On rich soil a light balanced feed in spring is sufficient — avoid overfeeding, which produces lax growth.
Watch For
- Aphids on soft new shoots in spring
- Root rot on waterlogged soil
Companions
Lavender, Rosemary, Sage, Santolina

Care Requirements
Light
Full sun
Needs at least 6 hours of direct sun per day. In shade it becomes lax and loses its aromatic intensity.
Watering
Low once established
Water regularly after planting until established (first growing season). After that, southernwood is drought-tolerant and rarely needs watering except in prolonged dry spells.
Fertilizing
Minimal — avoid rich feeding
Thrives in poor soil. A light balanced feed in spring is optional on very depleted ground. Avoid nitrogen-rich feeds which cause lax, unscented growth.
Pruning
Hard prune to 10–15 cm each spring
The essential annual task. Cut the whole plant back to 10–15 cm from the base in March–April before new growth begins. This keeps the plant bushy, compact, and productive for many years.
Soil
Poor, dry, well-drained
Prefers light, sandy or chalky, free-draining soil. Tolerates poor fertility. Will not tolerate waterlogged or heavy clay soils.
Growing Tips
Hard prune every spring
Cut the whole plant back to 10–15 cm from the base in March or April before new shoots appear. This is not optional — without it the plant becomes bare and woody at the centre within 2–3 years.
Poor soil is an advantage
Southernwood thrives on neglect in dry, infertile, free-draining soil. Rich or waterlogged soil produces lax, soft growth and shortens the plant's life.
Natural moth repellent
The strongly aromatic foliage repels clothes moths. Dry small bunches and place in wardrobes or drawers — an old cottage-garden tradition that works.
