How to Germinate Tarragon Seeds

Germinating tarragon seeds can be a rewarding process, though it’s worth noting that French tarragon (Artemisia dracunculus var. sativa) is usually propagated through cuttings or root divisions because its seeds are often sterile. However, Russian tarragon (Artemisia dracunculoides) can be grown from seeds. Here’s a step-by-step guide to germinate tarragon seeds:

Materials Needed:

• Tarragon seeds
• Seed-starting trays or small pots
• Seed-starting mix (a light, well-draining soil mix)
• Spray bottle
• Plastic wrap or a clear plastic dome
• Labels and markers

Steps to Germinate Tarragon Seeds:

1. Prepare the Seed-Starting Mix:
   • Fill your seed-starting trays or small pots with the seed-starting mix. Lightly moisten the mix with water from a spray bottle. Ensure it’s evenly damp but not waterlogged.
2. Sow the Seeds:
   • Scatter the tarragon seeds thinly over the surface of the soil. Tarragon seeds are tiny, so handle them carefully.
   • Gently press the seeds into the soil using your fingers or a small piece of cardboard. Do not cover them with too much soil because they need light to germinate. Just a light dusting of soil or vermiculite will do.
3. Moisten the Seeds:
   • Lightly mist the soil surface again with water from a spray bottle to ensure good contact between the seeds and the seed-starting mix.
4. Create a Humid Environment:
   • Cover the seed tray or pots with plastic wrap or a clear plastic dome to retain moisture and create a humid environment. This helps to speed up germination.
5. Provide Adequate Light and Warmth:
   • Place the covered seed trays or pots in a warm location with plenty of indirect sunlight. A temperature range of 70-75°F (21-24°C) is ideal.
   • Alternatively, you can place them under grow lights if sufficient natural light is not available.
6. Monitor Moisture Levels:
   • Check the soil regularly to ensure it remains consistently moist but not soggy. Lightly mist with water as needed.
7. Germination Time:
   • Tarragon seeds typically take 10-14 days to germinate, although this can vary. Be patient and continue to provide the right conditions.
8. Transplanting Seedlings:
   • Once the seedlings have developed two sets of true leaves, they can be transplanted into larger pots or directly into the garden.
   • Harden off the seedlings by gradually exposing them to outdoor conditions over about a week before transplanting them permanently.

Additional Tips:

• Soil: Ensure the soil is well-draining and moderately fertile.
• Watering: After transplanting, water your tarragon plants regularly, especially during dry periods, but avoid overwatering.
• Sunlight: Tarragon prefers full sun but can tolerate partial shade.

By following these steps and providing the right conditions, you should be able to successfully germinate tarragon seeds and grow healthy plants.
