How to Grow Tarragon

Tarragon (Artemisia dracunculus) is a fragrant perennial herb prized for its anise‑like flavor and delicate leaves. French tarragon is grown from cuttings, while Russian tarragon can be grown from seed. It thrives in full sun, well‑drained soil, and moderate moisture. This guide explains planting, germination, care, harvesting, and climate considerations suitable for all regions.

Where Should You Plant Tarragon?

  • Best location: Full sun; tarragon grows strongest with bright, direct light.
  • Soil: Well‑drained, sandy or loamy soil; pH 6.0–7.5.
  • Moisture: Light, even moisture; avoid soggy soil to prevent root rot.

When Should You Plant Tarragon?

  • Start indoors: French tarragon must be started from cuttings; Russian tarragon seeds can be started 6–8 weeks before transplanting.
  • Transplanting: Move outdoors once frost danger has passed and soil warms.
  • Direct sow: Only possible with Russian tarragon; French tarragon does not produce viable seeds.

How Do You Plant Tarragon?

  • Depth: Sow Russian tarragon seeds on the soil surface; plant cuttings at the same depth they grew previously.
  • Spacing: Space plants 18–24 inches apart; tarragon forms bushy clumps.
  • Quantity: A few plants provide abundant foliage for culinary use.

Which Plants Grow Well With Tarragon?

  • Companions: Basil, chives, parsley, and other culinary herbs.
  • Avoid: Moisture‑loving plants that prefer richer, wetter soil.
  • Best pairing: Herbs that enjoy similar dry, sunny conditions.

How Do You Water and Feed Tarragon?

  • Watering: Water lightly; tarragon is drought‑tolerant once established.
  • Feeding: Minimal feeding required; too much fertilizer reduces flavor intensity.

How Do You Care for Tarragon?

  • Support: No support needed; plants form upright stems.
  • Weeding: Keep beds weed‑free to maintain airflow and reduce competition.
  • Pruning: Trim lightly to encourage branching and prevent legginess.
  • Winter care: Mulch lightly in cold climates; French tarragon dies back but returns in spring.

Can You Grow Tarragon in Containers?

  • Winter growing: Possible indoors with bright light; keep soil slightly dry.

What Pests or Diseases Affect Tarragon?

How Do You Harvest Tarragon?

  • Timing: Harvest once plants are well‑established; flavor is strongest in warm weather.
  • Leaves: Snip sprigs as needed; regular harvesting encourages new growth.
  • Seeds: French tarragon does not produce viable seeds; Russian tarragon seeds can be collected from dried flower heads.
