How to grow winter savoury
Overview
Winter savoury (Satureja montana) is a hardy perennial herb grown for its spicy, peppery leaves used in cooking. It thrives in full sun and well-drained soil, requiring minimal water once established. This Mediterranean native is ideal for dry, sunny spots in Australian gardens and provides year-round harvests.
Varieties
- Winter Savoury — Standard species (Satureja montana), hardy and reliable for Australian gardens.
- Variegata — Variegated form with cream-edged leaves; less vigorous but ornamental.
Soil Preparation
Winter savoury prefers poor to moderately fertile, well-drained soil with a pH of 6.0–7.5. Improve heavy clay with grit or sand to avoid waterlogging. Avoid rich, nitrogen-heavy soil as it reduces leaf flavour.
Growing Guide
Plant winter savoury in full sun in free-draining, slightly alkaline soil. Space plants 30cm apart to allow airflow. Sow seeds directly in spring after frost has passed, or start indoors 6–8 weeks before. Pinch out growing tips when young to encourage bushiness. Cut plants back by one-third after flowering to maintain a compact shape and promote fresh growth.
Sowing
Sow seeds 3mm deep in seed trays or directly in the garden after frost. Germination takes 10–14 days at 18–21°C. Thin seedlings to 30cm apart once they have two true leaves.
Care
Feed with a light application of balanced organic fertiliser in early spring. Prune back by one-third after flowering to maintain shape and vigour. Remove any dead or woody stems in late winter to rejuvenate the plant.
Companion Planting
Good near beans, as winter savoury is said to repel bean weevils and improve flavour. Also pairs well with other Mediterranean herbs like rosemary, thyme, sage, and lavender. Avoid planting alongside moisture-loving crops such as lettuce or mint, as savory prefers dry conditions.
Common Pests & Risks
Root rot is the main problem in wet or poorly drained soil; ensure excellent drainage. Aphids occasionally attack new growth; spray with neem oil or insecticidal soap. Good air circulation prevents fungal issues like powdery mildew in humid conditions.
Harvesting
Harvest sprigs from 15cm tall plants, cutting from the top down to encourage branching. For best flavour, pick just before flowers open; leaves become milder after flowering. Use fresh immediately, or hang sprigs to dry in a dark, airy place for storage.
In the Kitchen
Leaves have a peppery, thyme-like flavour that complements beans, meats, and stews. Harvest before flowering for strongest taste. Dry or freeze leaves for later use; they retain flavour well.
Troubleshooting
Yellow leaves: overwatering or poor drainage – reduce watering and improve soil. Leggy growth: not enough sun – move to full sun. Few leaves: needs pruning to stimulate new growth. White powdery coating: powdery mildew in humid conditions – improve air circulation. Root rot: ensure free-draining soil.
