Tarragon (Artemisia dracunculus), known for its aromatic leaves and distinct anise-like flavor, is a perennial herb widely used in culinary dishes, teas, and herbal remedies. It thrives in temperate climates and is a great addition to any kitchen garden, container, or herb bed. Tarragon is drought-tolerant, easy to grow, and provides fresh leaves for years when properly cared for.

How to Grow Tarragon

Planting:
Tarragon is best grown from root divisions or seedlings, as seeds of French tarragon are sterile. Start seeds indoors 6–8 weeks before the last frost or sow them directly outdoors after the danger of frost has passed. If planting seedlings or root divisions, wait until the soil has warmed to at least 50°F.

Spacing:
Space plants 18–24″ apart in the garden to allow for healthy growth and good air circulation. Tarragon is a compact plant, reaching 2–3 feet tall and about 1–2 feet wide.

Soil Requirements:
Tarragon prefers well-drained, slightly sandy soil with a pH between 6.5 and 7.5. Avoid heavy, clay-rich soils. Add compost or organic matter to improve drainage if necessary.

Sunlight:
Grow tarragon in full sun, receiving at least 6–8 hours of direct sunlight daily. In very hot climates, provide light afternoon shade to prevent scorching.

Growing Tarragon

Watering:
Water tarragon deeply but infrequently, allowing the soil to dry out between waterings. Overwatering can lead to root rot. Tarragon is drought-tolerant once established.

Mulching:
Apply a layer of mulch around the plant to retain soil moisture and suppress weeds. Avoid placing mulch directly against the stem to prevent rot.

Fertilizing:
Tarragon requires minimal fertilization. Use a balanced, slow-release fertilizer or add compost in early spring to promote growth. Avoid over-fertilizing, as it can dilute the herb’s flavor.

Pruning:
Regularly pinch back the growing tips to encourage bushier growth and prevent the plant from becoming woody. Remove flower buds as they appear to direct energy toward leaf production.

Winter Care:
In colder zones (USDA zones 4–6), protect tarragon with a layer of mulch or straw during winter. In warmer zones, it may remain evergreen. Divide the plant every 3–4 years to rejuvenate growth.

How and When to Harvest Tarragon

Harvest tarragon leaves throughout the growing season, starting once the plant reaches 6–8 inches in height. For the best flavor, pick leaves in the morning before the sun becomes intense. Use fresh or dry the leaves for later use. Cut back the plant in late summer to encourage a second flush of growth.

Tarragon Seed Saving

If growing tarragon, let the flowers bloom and form seed heads. Once the seeds are fully dry, cut the seed heads and shake them into a paper bag. Store seeds in a cool, dry place for planting the following season. French tarragon, however, does not produce viable seeds and must be propagated through cuttings or root divisions.

Tarragon is a versatile and low-maintenance herb that adds gourmet flavor to a variety of dishes. With proper care, it can be a productive addition to your garden for many years. Enjoy its fragrant leaves fresh or dried!
