Seedling
3-4 weeksTiny seedlings with narrow, delicate leaves emerge 10-14 days after planting. Growth is slow and tender during this stage.
Keep soil consistently moist but not waterlogged. Provide bright light. Thin seedlings to 2-3 inches apart. Maintain 70°F optimal temperature.
Vegetative Growth
6-8 weeksPlant develops multiple slender stems with thin, lance-shaped leaves. Height increases to 6-12 inches. Foliage becomes fuller and more aromatic.
Reduce watering frequency as plant matures. Fertilize every 2-3 weeks with balanced, dilute fertilizer. Pinch growing tips to encourage bushier growth.
Established Plant
Ongoing (years 2+)Mature plant reaches full height of 24-36 inches with dense foliage. Stems become slightly woody at base. Plant is fully winter-hardy for its zone.
Water deeply but infrequently; allow soil to dry between waterings. Fertilize once monthly if desired. Provide winter mulch in zones 3-5. Cut back stems annually in early spring.
Flowering
6-8 weeks in summerSmall, inconspicuous greenish-white or pale yellow flowers appear on terminal spikes in summer. Flowering can diminish leaf quality.
Pinch or deadhead flowers to redirect energy to foliage production. Many gardeners remove flower buds to maintain leaf flavor and tenderness.
Dormancy
3-4 months (varies by zone)In fall and winter, above-ground growth slows or dies back. Root system remains dormant but alive underground in perennial varieties.
Cut back dead stems to 1-2 inches above soil line in late fall. Apply 2-3 inches of mulch (straw, leaves) for insulation in cold zones. Reduce watering significantly.

Harvest Tips
Pinch or cut leaves regularly once plant is 6 inches tall to encourage bushier growth and discourage flowering. Harvest in early morning after dew dries for best flavor. Cut sprigs from the top; the plant regenerates from the base. Do not harvest more than one-third of the plant at once. For drying, cut stems just before flower buds open, when oil content is highest. Fresh leaves are more flavorful than dried.
Fun Facts
- 🌱 French tarragon (Artemisia dracunculus var. sativa) is the preferred culinary variety and cannot be grown from seed; it must be propagated by cuttings or root division. Russian tarragon (Artemisia dracunculus var. inodora) grows from seed but has inferior flavor.
- 🌱 The name 'tarragon' derives from the Old French 'estragon,' which comes from the Arabic 'tarkhon,' meaning 'little dragon'—possibly because the roots resemble a dragon or because it was believed to cure dragon bites.
- 🌱 Tarragon was not widely cultivated until the 16th century in Europe, when it was introduced through Spain by Moorish traders, and it became a staple of French royal cuisine.
