Best and Worst Companion Plants for Mint

Increase Crop Yields, Improve Soil Health, Use Garden Space Efficiently and Keep Pests at Bay

Mint is a valuable herb with a long history of use for culinary and medicinal purposes.

What is Mint?

  • Mint species (Mentha spp.) belong to the Lamiaceae family, along with basil, rosemary, sage, oregano, thyme, and lavender.
  • They are almost exclusively perennial herbs with square stems and opposite aromatic leaves.
  • In summer, they produce tiny, pale purple, pink, or white flowers that are arranged in whorls or crowded together in terminal spikes.
  • Mint is a popular herb to grow in gardens and is often used for culinary purposes.
  • Mints are very vigorous, such as Spearmint or Peppermint, and can be aggressive in gardens, spreading by stolons everywhere. To avoid this, it's recommended to plant mint in pots or raised beds or to use root barriers when planting it in the ground.

What Is Companion Planting?

Companion planting is an organic method of preventing or protecting plants from pests and diseases, attracting the right types of insects for pollination, enhancing nutrient uptake, and increasing crop production simply by growing specific plants near each other. In essence, companion planting helps bring a balanced ecosystem to your landscape, allowing nature to do its job.

Benefits of Companion Planting

1. Organic Pest control
Some plants can emit scents that either repel insects, attract them, or confuse insects or disease organisms in search of their favorite host plants. They make insects less likely to land on your garden vegetables.

2. Attracts beneficial insects
Some plants help attract beneficial insects, such as ladybugs, bees, and butterflies, that pollinate and help control harmful bugs. Beneficial insects feed on common garden pests, like aphids and caterpillars.

3. Provides necessary shade
Tall sun-loving plants offer shade to smaller shade-loving plants. This results in better products and can also potentially provide pest control. A good example is The Three Sisters Garden. Practiced by Native Americans thousands of years ago, this garden includes corn, beans, and squash. The tall corn provides shade for the lower squash but also stops the squash vine borer beetle.

4. Shelters plants
Some plants can provide windbreaks and prevent soil erosion. Strong winds can damage gardens by removing mulch, topsoil, and eroding beds and hillsides. Rain can also cause severe damage by beating down young seedlings. By carefully selecting the right ground cover, you can help prevent soil erosion.

5. Provides natural supports
Some companion plants can physically support each other, reducing the need for staking. The example of planting corn, beans, and squash together applies here again. Corn provides tall stalks for the beans to climb so that they are not out-competed by sprawling squash vines.

6. Saves space
Interplanting different crops greatly maximizes space and improves productivity in small gardens.

7. Enhances flavors
Some plants can subtly enhance the flavor of other plants. Most herbs have been found to enhance the flavor of fruits and vegetables grown nearby, and Basil grown beside tomatoes is an excellent example. Similarly, chamomile has an aromatic scent that is believed to improve the growth and flavor of cabbages, cucumbers, and onions when grown beside them.

8. Better soil quality and fertility
Some crops help fix nitrogen from the atmosphere and reduce fertilizer needs. Similarly, planting plants with different root structures together can aerate the soil and allow plants to pull nutrients from different parts of the soil.

Not only can companion planting helps your plants to grow better, but it also makes the vegetable garden more attractive thanks to the addition of colorful flowers that help or hinder nearby vegetables. Companion planting combines beauty and purpose to create an enjoyable, healthy environment.

Why is Mint an Excellent Companion Plant?

  1. Mint repels Pests: Mint has a strong scent that can deter pests such as aphids, black flies, cabbage moths, cabbage worms, cabbage maggots, flea beetles, squash bugs, whiteflies, and ants.

  2. Mint improves Growth: Mint is said to improve the growth of other plants by improving soil quality and releasing beneficial compounds into the soil.

  3. Mint attracts Beneficial Insects: Mint flowers are a source of nectar for beneficial insects such as bees, butterflies, hoverflies, and predatory wasps, which help pollinate nearby plants or prey on garden pests.

Do not plant Mint in the ground near your vegetables in order to prevent it from taking over your vegetable crops. Use Mint foliage as mulch or keep it in pots.
