What Not To Plant With Tarragon? The Impact of Incompatible Plants on Tarragon’s Growth and Flavor

Understanding the Problem

Growing tarragon can be a delightful experience, especially when you savor its unique flavor in your culinary creations. However, it is essential to recognize that not all plants get along well with this herb. Incompatible plants, such as parsley and thyme, can have a detrimental impact on tarragon’s growth and flavor profile, making it crucial to avoid certain plant combinations for successful cultivation of herbs.

Stunted Growth and Altered Flavor

When incompatible plants, such as thyme and parsley, are placed near tarragon, they can impede its growth and alter its flavor. Tarragon requires specific conditions to thrive optimally, and the presence of these herbs can disrupt these requirements. For instance, thyme and parsley may compete for nutrients or water, leaving tarragon deprived of essential resources necessary for healthy development.

Moreover, incompatible plants like thyme and parsley can release chemicals into the soil that hinder tarragon’s growth. These chemicals may inhibit the herb’s ability to absorb nutrients or even act as allelopathic agents, directly affecting its physiological processes. As a result, tarragon, when planted alongside herbs like thyme and parsley, may exhibit stunted growth or fail to reach its full potential.

In addition to diminished growth, incompatible plantings can also impact tarragon’s flavor. Tarragon is known for its distinct taste profile characterized by hints of licorice and anise, as well as the complementary flavors of thyme, parsley, oregano, and beans. However, when grown alongside incompatible plants, this unique flavor may become compromised or overshadowed by other flavors introduced by neighboring herbs or vegetables.

Avoiding Incompatibility Issues

To ensure optimal growth and preserve tarragon’s unique flavor profile, it is vital to avoid planting certain companions alongside this herb. By understanding which plants are incompatible with tarragon, such as thyme, parsley, and beans, you can create an environment conducive to its flourishing.

  1. Mint, one of the popular herbs in an herb garden, is prized for its refreshing aroma and taste in various dishes and beverages. However, it should not be planted near tarragon, as mint is an aggressive plant that can quickly overtake tarragon, leaving it struggling to survive. So, when planning your herb garden, be mindful of the companion plants and avoid planting mint near tarragon.
  2. Basil and tarragon are both popular herbs for the kitchen. However, it is not recommended to grow these companion plants together in the same soil. Basil has a tendency to dominate the growing space, potentially hindering the growth of tarragon.
  3. Fennel and tarragon are both herbs commonly used in the kitchen. While they share a similar licorice-like flavor, planting them together is not advisable. Fennel has a tendency to spread rapidly and compete for resources, potentially stifling tarragon’s growth. This can be problematic when using these herbs in soups or as companion plants.
  4. Companion plants, such as cilantro and tarragon, can have different effects on each other. While cilantro adds a refreshing touch to many dishes, it can negatively impact tarragon when planted nearby. Cilantro has a short lifespan and bolts quickly, which may cast unwanted shade on the delicate tarragon leaves. So, when planning your herb garden, consider the compatibility of companion plants and the impact they may have on each other’s growth in the soil. This is especially important in a kitchen garden where you want to ensure the best conditions for your herbs to thrive.
  5. Tomatoes and tarragon are not good garden companions. Tomatoes, being heavy feeders, require ample nutrients from the soil, leaving little for the neighboring tarragon plants. However, both herbs can be used in a variety of delicious soups in the kitchen.

Avoid These 6 Plants When Growing Tarragon

Negative Impact on Tarragon Growth

Growing tarragon in your kitchen garden can be delightful, as this herb’s aromatic leaves and delicate flavor can enhance various culinary dishes. However, it’s important to know which companion plants to avoid planting alongside tarragon. Certain vegetables have been found to negatively impact the soil and hinder the growth and vitality of tarragon. Let’s explore six common plants that should be kept far away from your beloved tarragon patch.

Tomatoes: A Bad Match for Tarragon

While tomatoes are a popular choice for many kitchen gardens, they do not make good companions for tarragon herbs. Tomatoes are known for their high nitrogen requirements, which can compete with tarragon’s need for well-balanced soil conditions. Tomatoes attract pests like aphids and hornworms that could harm the tender leaves of the tarragon plant. Therefore, it is not recommended to use tomatoes in soups that include tarragon herbs.

Cabbage: Not a Friendly Neighbor

Cabbage is another kitchen plant that should be avoided when growing tarragon herbs. Both cabbage and tarragon require ample space in the soil to spread their roots and grow successfully as companion plants. Planting them together may result in overcrowding, leading to stunted growth or poor yields for both plants.

Broccoli and Kale: Keep Them Apart

Broccoli and kale, two popular cruciferous vegetables, require ample space to grow well. However, when planted alongside tarragon, these leafy greens may overshadow the herb, affecting its access to sunlight. This can be problematic for the kitchen garden, where companion plants like herbs play a crucial role.

Peppers: Spice Up Your Garden Separately

Peppers, a fiery kitchen staple, add a kick to our meals. However, they should not be grown alongside tarragon, an herb that prefers partial shade conditions. Peppers require warm temperatures and full sun exposure to flourish, while tarragon’s needs conflict with these requirements. This conflicting companion planting may compromise the growth of both herbs.

Potatoes: Keep Them at a Distance

Potatoes and tarragon may not be the best companions in your kitchen garden. Potatoes spread rapidly, competing with tarragon for nutrients and space. This competition can lead to stunted growth and reduced productivity for both plants.

To ensure a healthy and thriving tarragon in your kitchen, it is crucial to avoid planting it alongside these six companion plants. By providing sufficient space, sunlight, and balanced soil conditions specific to tarragon’s needs, you can maximize its growth potential. Remember, a well-planned garden layout will benefit all your plants, including your kitchen companion tarragon, in the long run.

The Negative Effects of Garlic on Tarragon

Inhibiting Growth with Allelopathic Properties

Garlic, a beloved ingredient in many French kitchen sauces, may not be the best companion for your tarragon plants. This pungent herb possesses allelopathic properties that can inhibit the growth and development of nearby tarragon in the kitchen. Allelopathy refers to the chemical interactions between kitchen plants, where one plant releases substances that affect the growth or germination of another kitchen plant.

When garlic is planted near tarragon in the kitchen, it releases certain compounds into the soil that can hinder the growth of neighboring tarragon plants. These kitchen compounds act as natural herbicides, suppressing the growth of other kitchen plants and potentially stunting or even killing off your precious kitchen tarragon crop.

Understanding the Negative Impact

To truly grasp why garlic has such a detrimental effect on tarragon, it’s important to understand how these allelopathic properties work. Garlic contains sulfur-based compounds such as allicin and diallyl disulfide. When these compounds are released into the soil through root exudates or decomposition, they create an inhospitable environment for nearby plants like tarragon.

The sulfur-based compounds in garlic interfere with essential biological processes in tarragon, a companion plant, by inhibiting enzyme activity and disrupting cell membranes. This disruption hampers nutrient absorption and overall plant health. As a result, tarragon, a companion plant, struggles to grow properly, leading to stunted growth, yellowing leaves, and reduced vigor.

Keeping Garlic at a Distance

To ensure the optimal growth of your tarragon crop, it’s best to avoid planting garlic together with it. Companion plants like garlic can have a negative impact on tarragon’s growth.

  1. Allelopathic Interference: Planting garlic near tarragon exposes the latter to harmful chemicals that impede its growth.
  2. Competition for Resources: Both garlic and tarragon require similar soil conditions and nutrients. Planting them together can lead to fierce competition, resulting in weaker plants overall.
  3. Aromatic Overload: Garlic’s strong aroma can overpower the delicate fragrance of tarragon, affecting its flavor when used in culinary applications.

The Detrimental Impact

Planting garlic near tarragon can have several negative consequences for your herb garden:

  1. Stunted Growth: Tarragon plants may experience stunted growth due to the inhibitory effects of garlic’s allelopathic compounds.
  2. Reduced Yield: With compromised growth, tarragon may produce fewer leaves, reducing your overall yield.
  3. Weakened Flavor: Tarragon’s distinct flavor profile can be altered when grown alongside garlic, potentially diminishing its culinary appeal.

To ensure the health and productivity of your tarragon crop, it is advisable to plant it away from garlic or any other plants known for their allelopathic properties. By providing a separate growing space for your tarragon, you give it the best chance to thrive without interference from neighboring herbs like garlic.


In conclusion, it’s important to be mindful of the plants you choose to grow alongside tarragon. Marjoram and oregano may seem like logical companions, but they can actually hinder the growth and flavor of tarragon. There are several other plants that should be avoided when cultivating tarragon, including basil, dill, parsley, coriander, and fennel.

One particularly detrimental plant to avoid pairing with tarragon is garlic. While garlic is a popular herb in its own right, it can have negative effects on the growth and development of tarragon. The strong scent and compounds released by garlic can interfere with the delicate flavors of tarragon and compromise its overall quality.

To ensure optimal growth and flavor for your tarragon plants, it’s crucial to pay attention to their companions in your garden. By avoiding incompatible plants like marjoram, oregano, basil, dill, parsley, coriander, fennel, and garlic when growing tarragon, you can help create an environment that promotes healthy growth and enhances the unique taste of this prized herb.
