In this comprehensive guide, we’ll explore the essential steps to successfully grow tarragon at home, from choosing the right location to caring for the plants and enjoying the flavorful harvest.

A Flavorful Addition to Your Garden

Tarragon is a perennial herb that belongs to the sunflower family. Its slender, elongated leaves are highly aromatic and impart a distinctive anise-like flavor to dishes. Tarragon has been used for centuries in various culinary traditions, particularly in French cuisine, where it’s a key ingredient in many classic recipes, such as béarnaise sauce and fines herbes.

By growing tarragon at home, you’ll have access to fresh, flavorful leaves that can elevate your cooking to new heights. Furthermore, the herb’s delicate appearance and pleasant aroma make it an attractive addition to any garden, adding visual interest and fragrance to your outdoor space.

Choose the Right Spot

Sunlight Requirements

The first step in growing tarragon is selecting the ideal location. Tarragon thrives in sunny spots, so find an area that receives at least six hours of direct sunlight daily. Full sun exposure is essential for the plant to grow vigorously and develop its signature flavor.

If you live in a particularly hot climate, consider providing some afternoon shade to prevent the plants from becoming too stressed during the hottest parts of the day.

Soil Drainage Considerations

Tarragon prefers well-drained soil and doesn’t tolerate waterlogging. Ensure the soil has good drainage, as standing water can lead to root rot and other problems. If your soil is heavy or clay-based, consider amending it with compost or sand to improve drainage.

Spatial Requirements

When planning your tarragon garden, consider the space requirements of the plants. Tarragon can grow up to two feet in height and spread, so ensure you allocate enough space for each plant to thrive. A general rule of thumb is to space the plants 18 to 24 inches apart, allowing for proper air circulation and easy access for maintenance.

Soil Preparation

Importance of Testing Soil pH

Before planting, it’s crucial to prepare the soil properly. Test the pH level, as tarragon prefers a slightly acidic to neutral range of 6.0-7.0. If the pH is too low or high, amend the soil with the appropriate materials to bring it within the desired range.

• For acidic soil (pH below 6.0), add limestone or wood ash to raise the pH.
• For alkaline soil (pH above 7.0), add sulfur, peat moss, or composted pine needles to lower the pH.

Amending Soil with Organic Matter

Regardless of your soil’s pH, it’s always beneficial to incorporate organic matter, such as compost or well-rotted manure. Organic matter improves soil structure, enhances water retention, and provides essential nutrients for plant growth.

Spread a 2-4 inch layer of organic matter over the planting area and mix it thoroughly into the top 6-8 inches of soil. This will create a rich, fertile environment for your tarragon plants to thrive.

Maintaining Proper Soil Moisture

Tarragon prefers slightly dry conditions, but it’s essential to maintain proper soil moisture during the growing season. Before planting, water the soil thoroughly to ensure it’s evenly moist throughout the root zone.

During the growing season, monitor the soil moisture level regularly and water the plants when the top inch or two of soil becomes dry. Avoid overwatering, as this can lead to root rot and other issues.

Selecting Tarragon Varieties

French Tarragon (Artemisia dracunculus)

French tarragon is the variety most prized for its superior flavor and culinary uses. Its narrow, dark green leaves have a distinct licorice-like aroma and taste, making it a popular choice for flavoring sauces, vinegars, and dressings.

French tarragon is a perennial herb that grows up to 2 feet tall and spreads slowly through underground rhizomes. It’s important to note that French tarragon does not produce viable seeds, so it must be propagated through root division or stem cuttings.

Russian Tarragon (Artemisia dracunculoides)

Russian tarragon is a different species from French tarragon and has a milder, less intense flavor. While it can be used in cooking, it’s generally considered a poor substitute for the real thing.

One advantage of Russian tarragon is that it can be grown from seeds, making it more accessible to home gardeners. However, its flavor is often described as bitter or grassy, lacking the distinctive anise notes of French tarragon.

Comparison of Flavors and Growing Conditions

When selecting tarragon varieties, it’s essential to consider the desired flavor profile and growing conditions. Here’s a quick comparison:

For the best culinary experience, most gardeners and chefs recommend growing French tarragon, as its unique flavor is unmatched in the tarragon world.

Planting Methods

Starting from Seeds or Transplants

Tarragon can be grown from seeds or transplants, depending on the variety and your preferences.

• Starting from Seeds: Russian tarragon can be started from seeds, but French tarragon seeds are not viable. To grow French tarragon from seeds, you’ll need to purchase seeds specifically labeled as “true French tarragon.” Sow the seeds indoors in early spring, and transplant the seedlings outdoors after the last frost.
• Using Transplants: For French tarragon, or if you prefer a head start, you can purchase transplants from a nursery or online retailer. Plant them directly in the ground or containers, ensuring adequate spacing between plants to allow for proper growth.

Container Gardening for Tarragon

Tarragon is well-suited for container gardening, making it an excellent choice for those with limited outdoor space or for those who want to grow the herb indoors.

Choose a container at least 12 inches in diameter and 8-10 inches deep, with drainage holes at the bottom. Use a well-draining potting mix specifically formulated for containers, and add a slow-release fertilizer to provide nutrients throughout the growing season.

Spacing and Depth Guidelines

When planting tarragon, follow these spacing and depth guidelines:

• Spacing: Plant tarragon transplants or seedlings 18-24 inches apart to allow for proper growth and air circulation.
• Depth: Plant the tarragon at the same depth it was growing in the container or seed tray, ensuring the crown (where the stem meets the roots) is at soil level.

Gently firm the soil around the plant after planting, and water thoroughly to settle the roots.

Plant Care

Watering Requirements

Tarragon plants require consistent watering to establish a strong root system and maintain healthy growth. Here are some guidelines for watering your tarragon plants:

• Newly Planted: Water newly planted tarragon regularly, keeping the soil consistently moist but not waterlogged. This will help the roots establish themselves in their new environment.
• Established Plants: Once established, tarragon plants are relatively drought-tolerant. Water them deeply once or twice a week, depending on the weather conditions and soil drainage.
• Mulching: Apply a 2-3 inch layer of mulch around the plants to help retain soil moisture and suppress weed growth.
• Timing: Water tarragon plants in the morning or evening to minimize evaporation and reduce the risk of fungal diseases.

Fertilizing Guidelines

While tarragon is not a heavy feeder, providing some nutrients can help promote healthy growth and abundant leaf production. Follow these fertilizing guidelines:

• Organic Fertilizers: Use an organic, balanced fertilizer with an NPK ratio of 10-10-10 or 12-12-12.

• Application Rate: Apply the fertilizer at the recommended rate on the package, typically around 1 tablespoon per square foot of planting area.
• Timing: Fertilize tarragon plants in early spring, just as new growth begins to appear, and again in midsummer to support continued growth and leaf production.
• Method: Sprinkle the fertilizer evenly around the base of the plants, being careful not to let it touch the stems or leaves. Water thoroughly after applying to help the nutrients penetrate the soil.

Avoid over-fertilizing, as this can result in excessive leaf growth at the expense of flavor.

Pruning and Harvesting Techniques

Regular pruning and harvesting are essential for maintaining the health and productivity of your tarragon plants. Follow these guidelines:

• Early Spring Pruning: In early spring, before new growth begins, prune back the previous year’s growth, leaving about 2-3 inches of stem above the soil level. This encourages fresh, new growth and prevents the plant from becoming woody and unproductive.
• Harvesting: Once the plants reach a height of 6-8 inches, you can begin harvesting the leaves. Use clean, sharp scissors or pruning shears to snip off the stems just above a set of leaves. Avoid removing more than one-third of the plant’s foliage at a time to prevent over-harvesting.
• Continuous Harvesting: Tarragon is a cut-and-come-again herb, meaning you can continuously harvest the leaves throughout the growing season. Regular harvesting encourages bushier growth and more leaf production.
• Late Season Pruning: In late summer or early fall, prune back the plants by about one-third to help them prepare for dormancy and rejuvenate for the following growing season.

Remember, the best time to harvest tarragon leaves is in the morning, when the essential oils that give the herb its flavor are most concentrated.

Pest and Disease Management

While tarragon is generally a low-maintenance herb, it’s essential to be aware of common pests and diseases that may affect its growth and take preventative measures to keep your plants healthy.
