How to Harvest Tarragon: Unlock the Flavor of Your Herb Garden
Harvesting tarragon correctly ensures you get the most flavor and encourages ongoing growth. To harvest, snip off the top third of the stems just before the plant flowers.
The Aromatic Allure of Tarragon
Tarragon, scientifically known as Artemisia dracunculus, is a perennial herb prized for its distinctive anise-like flavor. It’s a staple in French cuisine, adding a sophisticated touch to sauces, salads, and meat dishes. Growing your own tarragon offers a readily available supply of this flavorful herb, and knowing how to harvest it properly ensures a continuous bounty throughout the growing season.
Why Harvest Tarragon?
Harvesting isn’t just about obtaining the herb for culinary use; it’s also crucial for the plant’s overall health and productivity. Regular harvesting encourages bushier growth, preventing the plant from becoming leggy and unproductive. It also concentrates the plant’s energy into producing more flavorful leaves, giving you a superior culinary experience.
When to Harvest Tarragon
The optimal time to harvest tarragon is just before the plant begins to flower. This is when the leaves contain the highest concentration of essential oils, responsible for the herb’s characteristic flavor. As a general rule, you can start harvesting tarragon a few weeks after planting or when the plant reaches about 6-8 inches in height.
Here’s a simple guide:
- Spring/Early Summer: Primary harvesting period.
- Throughout the Season: Harvest as needed, but avoid heavy harvesting late in the season.
How to Harvest Tarragon: A Step-by-Step Guide
Harvesting tarragon is a straightforward process. Here’s a step-by-step guide to ensure you do it correctly:
- Choose Your Tools: Use sharp, clean scissors or pruning shears. This minimizes damage to the plant.
- Identify the Stems: Select stems that are healthy and vibrant.
- Make the Cut: Cut the top one-third of the stem, just above a leaf node (where leaves emerge from the stem).
- Leave Enough Growth: Ensure you leave enough of the plant for continued growth (at least a few inches).
- Repeat Regularly: Harvest regularly to encourage new growth.
Drying and Storing Tarragon
Fresh tarragon is delightful, but drying and storing it allows you to enjoy its flavor year-round.
- Air Drying: Tie the stems in small bundles and hang them upside down in a cool, dark, and well-ventilated area.
- Oven Drying: Spread the leaves in a single layer on a baking sheet and dry them in a very low oven (around 170°F or 77°C) until they are brittle.
- Freezing: Chop the leaves and freeze them in ice cube trays with water or olive oil.
Store dried tarragon in airtight containers in a cool, dark place. Frozen tarragon is best used within a few months.
Distinguishing Between French and Russian Tarragon
There are two main types of tarragon: French and Russian. French tarragon ( Artemisia dracunculus var. sativa) is the variety prized for its superior flavor. Russian tarragon ( Artemisia dracunculus) is easier to grow from seed but has a much weaker flavor.
Here’s a table comparing the two:
| Feature | French Tarragon | Russian Tarragon |
|---|---|---|
| Flavor | Strong, anise-like | Weak, less pronounced |
| Propagation | Cuttings or division | Seeds or division |
| Hardiness | Less hardy | More hardy |
Common Mistakes to Avoid
- Over-harvesting: Avoid removing too much of the plant at once, as this can weaken it.
- Harvesting in the Heat of the Day: The essential oils are most concentrated in the morning.
- Using Dull Tools: Dull tools can crush the stems and introduce disease.
- Forgetting to Dry or Freeze: Don’t let your harvest go to waste. Preserve it for later use.
