Mint is one of the most popular and versatile herbs, widely known for its refreshing flavor and medicinal properties. Whether you’re growing it in your garden, on your windowsill, or in a container, mint thrives in almost any environment.
However, despite its hardy nature, mint has specific companion plants that can help improve its growth, enhance its flavors, and even protect it from pests. Companion planting is the practice of growing certain plants together to benefit each other, whether by deterring pests, enhancing flavor, or supporting healthy growth.
In this post, we will explore the benefits of companion planting for mint, highlight the best plants to grow with mint, list plants to avoid, and provide helpful tips for successful companion planting.
Why You Should Consider Companion Planting for Mint
Mint is a fast-growing, aggressive herb that can quickly take over garden spaces if not properly controlled. It spreads through runners, and without careful management, it may crowd out other plants and become invasive. Companion planting offers an excellent solution to this issue by pairing mint with other plants that complement its growth, deter pests, and create a more balanced garden environment.
Moreover, mint has some specific growing needs. While it prefers rich, moist soil and partial sunlight, certain companion plants can provide complementary benefits that boost mint’s health. Whether you’re growing mint for culinary use or as a natural remedy, strategic pairing with other plants can help improve your gardening experience.
Companion plants also contribute to a more biodiverse ecosystem. By choosing plants that are beneficial to mint, you reduce the likelihood of pests or diseases overwhelming your garden. For instance, certain plants can help attract beneficial insects that control pests, or provide shade that protects mint from the harsh midday sun. Additionally, companion plants can encourage soil aeration, which benefits mint’s root system.
Best Companion Plants for Mint
When selecting companion plants for mint, consider plants that share similar growing conditions or provide some specific benefits. Below are some of the best companion plants to grow alongside mint:
1. Basil
Basil is an excellent companion for mint, especially because both herbs share similar growing conditions. Both mint and basil thrive in moist, well-drained soil with partial to full sunlight. Additionally, basil can help attract beneficial insects, like bees and butterflies, which pollinate both basil and mint flowers. The scent of basil also complements mint and may deter pests like aphids and mosquitoes.
2. Lemon Balm
Lemon balm is another mint-like herb that benefits from companion planting with mint. With a similar growth habit and flavor profile, lemon balm can provide an aromatic boost to your mint garden. Both plants grow well in slightly shady areas and enjoy similar moisture levels. Lemon balm can even help reduce the spread of mint by competing for space, keeping mint’s aggressive growth in check.
3. Chives
Chives are a perfect companion for mint due to their ability to deter pests like aphids, which commonly attack mint plants. By planting chives nearby, you help protect mint from harmful insects while allowing both plants to thrive. Additionally, the mild flavor of chives complements the bold taste of mint, making them an ideal pairing for culinary purposes. Chives grow well in similar soil conditions, needing good drainage and a moderate amount of sunlight.
4. Cabbage Family (Brassicas)
Mint also benefits from the presence of brassicas, such as cabbage, broccoli, and kale. These plants can help keep pests like cabbage worms and aphids away from mint. The scent of mint repels these pests, creating a protective barrier around the brassicas. Additionally, the large leaves of brassicas provide some shade for mint, which can be beneficial during the hottest part of the day.
5. Yarrow
Yarrow is a perennial herb known for attracting beneficial insects, such as ladybugs, which can help control aphids and other pests that might harm mint. Yarrow also improves soil health by attracting pollinators and enriching the surrounding soil. Planting yarrow near mint can help promote healthy growth and reduce pest pressure, making it a great companion for mint in any garden setting.
6. Marigolds
Marigolds are a fantastic companion plant for mint because of their pest-repellent properties. Marigolds naturally repel a variety of harmful insects, including aphids, whiteflies, and nematodes, which are common mint pests. The bright flowers of marigolds also attract pollinators, which is beneficial for the entire garden. Planting marigolds near mint can help reduce pest damage and increase the overall health of your garden.
Plants to Avoid Planting Near Mint
While companion planting can benefit mint, it’s equally important to know which plants to avoid planting nearby. Some plants can inhibit mint’s growth or attract pests that damage it. Here are a few plants you should avoid growing near mint:
1. Fennel
Fennel is a beautiful herb, but it is not a good companion for mint. Fennel tends to release allelopathic chemicals into the soil, which can inhibit the growth of nearby plants, including mint. This can lead to stunted growth or poor overall health in mint plants. Additionally, fennel’s tall and bushy growth habit can overshadow mint, blocking its access to sunlight and space.
2. Tomatoes
While mint and tomatoes may seem like a natural combination for a kitchen garden, they are not the best companions. Mint can overshadow tomato plants, competing for space and nutrients. Moreover, mint’s strong growth habit can restrict airflow around tomato plants, potentially leading to fungal diseases. For the best results, it’s advisable to grow mint in a separate pot or container away from tomatoes.
3. Carrots
Carrots and mint do not make great companions due to their different growing habits. Mint has an aggressive growth pattern, while carrots grow more slowly. Mint’s rapid spreading can crowd out the space carrots need to grow, resulting in poor yields. Additionally, mint’s invasive nature can interfere with the development of carrot roots, leading to small or malformed vegetables.
4. Parsley
Although parsley and mint have similar growing conditions, they do not always coexist peacefully. Parsley tends to attract aphids, and mint may not be able to prevent aphid infestations as effectively as it does with other plants. This can lead to pests affecting both plants, reducing their overall health and productivity.
5. Cucumbers
Cucumbers and mint are not the best match due to mint’s aggressive growth habit, which can overrun cucumber vines. Mint’s spreading roots may also compete with cucumbers for nutrients and moisture, hindering the cucumber plants’ growth. It’s better to grow mint in containers or away from cucumber plants to prevent overcrowding and ensure the best results for both crops.
Tips for Growing Companion Plants with Mint
Now that you know the best companion plants for mint and the ones to avoid, here are a few tips to ensure a successful companion planting experience:
1. Use Containers for Mint
To prevent mint from becoming too invasive, consider growing it in containers. This allows you to control its spread and makes it easier to pair it with other plants without mint taking over the garden. You can place mint containers near companion plants like basil, chives, or marigolds for mutual benefit.
2. Control Mint’s Growth
If you’re planting mint directly in the garden, be sure to control its growth. Use a physical barrier like garden edging or a large pot sunk into the ground to contain its spread. This will keep it from taking over neighboring plants while still benefiting from the advantages of companion planting.
3. Ensure Proper Spacing
While mint can benefit from the presence of certain plants, it’s essential to maintain enough spacing between them. This ensures that both plants have room to grow and access the necessary resources, like sunlight, water, and nutrients. Be mindful of the growth habits of both mint and its companion plants to avoid overcrowding.
4. Monitor Soil Health
Healthy soil is crucial for growing mint and its companions. Mint enjoys rich, moist soil, so ensure that your garden bed or containers are well-draining and nutrient-rich. Regularly amend the soil with compost or organic matter to maintain soil health and support the growth of both mint and its companion plants.
5. Rotate Plants Regularly
Companion planting is most effective when you rotate plants regularly to avoid nutrient depletion and pest buildup. Consider rotating mint with other herbs or vegetables each season to ensure the soil remains healthy and pests are kept in check.
Conclusion
Companion planting for mint is a great way to improve the growth, health, and flavor of your mint plants. By carefully selecting companion plants, you can deter pests, promote biodiversity, and create a harmonious garden environment.
While mint pairs well with herbs like basil, chives, and lemon balm, it’s important to avoid planting it with aggressive plants like fennel or vegetables like tomatoes that may compete for space and nutrients. With proper care, companion planting can enhance your mint-growing experience and contribute to a more successful and thriving garden.
