Advanced Techniques for Propagating Tarragon in a Greenhouse

Are you looking to expand your tarragon crop in a controlled environment? In this article, we will explore advanced techniques for propagating tarragon in a greenhouse. From choosing the right propagation method to providing optimal growing conditions, we will cover everything you need to know to successfully propagate tarragon plants in your greenhouse. Whether you are a seasoned gardener or just starting out, these techniques will help you achieve a bountiful tarragon harvest.

Choosing the Right Tarragon Variety for Propagation

Considerations for selecting the appropriate tarragon variety

When it comes to propagating tarragon in a greenhouse, choosing the right variety is crucial for success. Considerations for selecting the appropriate tarragon variety include:

  1. French Tarragon (Artemisia dracunculus var. sativa): French tarragon is the most commonly used variety for culinary purposes due to its superior flavor. It is sterile and cannot produce viable seeds, so it must be propagated through root division or cuttings.

  2. Russian Tarragon (Artemisia dracunculoides): Russian tarragon is a hardier variety than French tarragon, but it lacks the same intense flavor. It can be grown from seeds, making it easier to propagate.

  3. Mexican Tarragon (Tagetes lucida): Also known as Mexican mint marigold, this variety has a similar flavor to French tarragon but is easier to grow in warmer climates. It is propagated from seeds.

  4. Wild Tarragon (Artemisia dracunculus var. dracunculoides): This variety is native to North America and has a more bitter flavor than French tarragon. It can be propagated from seeds or cuttings.

Benefits of choosing specific varieties for greenhouse propagation

Selecting the right tarragon variety for greenhouse propagation offers several benefits:

  1. Flavor: French tarragon is prized for its superior flavor, making it a popular choice for culinary uses. By choosing this variety for propagation, you can ensure a high-quality end product.

  2. Adaptability: Different tarragon varieties have varying levels of hardiness and adaptability to different growing conditions. By selecting the appropriate variety for your greenhouse environment, you can maximize growth and yield.

  3. Ease of propagation: Some tarragon varieties, such as Russian tarragon and Mexican tarragon, are easier to propagate from seeds compared to French tarragon, which requires root division or cuttings. Choosing a variety that is simpler to propagate can streamline the propagation process in a greenhouse setting.

  4. Culinary versatility: Each tarragon variety has its own unique flavor profile, allowing for culinary experimentation and versatility. By selecting specific varieties for propagation, you can cater to different culinary preferences and applications.

    Preparing the Greenhouse Environment for Tarragon Propagation

Optimal temperature and humidity levels

To successfully propagate tarragon in a greenhouse, it is crucial to maintain optimal temperature and humidity levels. Tarragon thrives in temperatures between 60-70°F (15-21°C) during the day and slightly cooler temperatures at night. Additionally, the humidity levels should be around 50-70% to ensure proper growth and prevent the plants from drying out.

Lighting requirements for tarragon propagation

Tarragon requires plenty of light to grow and propagate successfully. When setting up your greenhouse for tarragon propagation, make sure to place the plants in an area that receives at least 6-8 hours of sunlight per day. If natural light is insufficient, consider supplementing with grow lights to ensure the plants receive the necessary light they need to thrive.

Soil and container considerations

When propagating tarragon in a greenhouse, it is essential to use well-draining soil to prevent root rot. A mixture of potting soil and perlite or sand works well for tarragon plants. Additionally, choose containers that have drainage holes to allow excess water to escape and prevent waterlogging. Terracotta pots or plastic containers are suitable options for tarragon propagation. Remember to provide adequate space for the plants to grow and spread their roots comfortably.

Propagation Methods for Tarragon in a Greenhouse

When it comes to propagating tarragon in a greenhouse, there are several advanced techniques that can be utilized to ensure successful growth. In this article, we will explore three main methods of propagation: seed propagation, cutting propagation, and division and root separation.

Seed Propagation Techniques

Seed propagation is a popular method for starting new tarragon plants in a greenhouse. To successfully propagate tarragon from seeds, it is important to first ensure that the seeds are of high quality and have been properly stored. Sow the seeds in a well-draining soil mix, keeping them moist but not waterlogged. Germination typically takes around 2-3 weeks, after which the seedlings can be transplanted into individual pots.

Cutting Propagation Methods

Cutting propagation is another effective way to propagate tarragon in a greenhouse. To propagate tarragon from cuttings, select a healthy stem and make a clean cut just below a node. Remove any lower leaves and dip the cutting in a rooting hormone before placing it in a pot with a well-draining soil mix. Keep the cutting moist and provide it with indirect sunlight until roots develop, usually within 2-4 weeks.

Division and Root Separation Process

Division and root separation is a method commonly used for propagating mature tarragon plants in a greenhouse. To divide a tarragon plant, carefully dig it up and separate the root ball into multiple sections, ensuring that each section has both roots and shoots. Replant the divisions in individual pots with fresh soil and water them thoroughly. Division is a quick and efficient way to propagate tarragon, especially for plants that have outgrown their current containers.

By utilizing these advanced propagation techniques, you can easily propagate tarragon in your greenhouse and ensure a bountiful harvest of this flavorful herb. Experiment with different methods to find the one that works best for you and enjoy the benefits of growing your own tarragon plants.

Maintaining Tarragon Plants in a Greenhouse

When it comes to successfully propagating and growing tarragon in a greenhouse, there are several key maintenance tasks that are essential to ensure healthy and thriving plants. Proper watering and fertilization, pest and disease management strategies, as well as pruning and harvesting tips, are all crucial aspects of maintaining tarragon plants in a greenhouse.

Proper watering and fertilization

Tarragon plants prefer well-draining soil and should be watered regularly to keep the soil consistently moist but not waterlogged. It is important to water the plants at the base to avoid wetting the foliage, as this can lead to disease issues. Additionally, tarragon plants benefit from regular fertilization with a balanced fertilizer to promote healthy growth and abundant foliage.

Pest and disease management strategies

One common pest that can affect tarragon plants in a greenhouse is aphids. To prevent aphid infestations, regularly inspect the plants for signs of pests and use natural remedies such as insecticidal soap or neem oil to control them. Additionally, practicing good greenhouse hygiene by removing any dead or diseased plant material can help prevent the spread of diseases.

Pruning and harvesting tips

Regular pruning is essential to keep tarragon plants in a greenhouse healthy and productive. Prune the plants regularly to remove any dead or yellowing leaves, as well as to encourage bushier growth. When harvesting tarragon, it is best to cut the stems just above a leaf node to promote new growth. Harvesting the leaves in the morning when their flavor is at its peak can ensure the best quality tarragon for culinary use.

By following these maintenance tips for tarragon plants in a greenhouse, you can ensure that your plants thrive and produce an abundance of flavorful leaves for all your culinary needs.


In conclusion, propagating tarragon in a greenhouse can be a rewarding and efficient way to ensure a bountiful supply of this versatile herb. By utilizing advanced techniques such as stem cuttings, division, and layering, gardeners can successfully propagate tarragon year-round and enjoy its fresh flavors in their culinary creations. With proper care and attention to detail, tarragon plants can thrive in a greenhouse environment, providing a consistent source of this beloved herb for years to come. By incorporating these techniques into your greenhouse gardening routine, you can enjoy the benefits of fresh tarragon and elevate your cooking to new heights.
