20 Basil Companion Plants for a Beautiful Garden All Season Long

Basil #Basil

Basil is known as an easy-to-grow herb that can bring your first harvest just a month after sowing, but it’s also one that easily falls victim to insects or poor soil quality. Luckily, companion plants like asparagus, dill, tomatoes, and peppers can help provide a better environment for basil.

Well-chosen companion plants will help keep destructive and harmful insects away from basil, enhance its flavor by enriching the nutrients within the soil, and create a growing environment that will help both plants thrive.

Here are 20 of the best companion plants for basil that you can plant in your garden for a delicious harvest.

Asparagus attracts ladybugs, which are incredibly effective at eating the aphids that are known to attack basil. Additionally, the aroma of basil keeps the asparagus beetle away, making it a mutually beneficial relationship.

  • Name: Asparagus (Asparagus officinalis)

  • USDA Hardiness Zones: 3-10

  • Light: Full sun

  • Soil: Sandy, loamy, neutral acidic

    Chamomile Flowers

    Not only does chamomile have a pleasant fragrance that gardeners love to use in tea, that aroma also helps enhance the growth and flavor of basil plants nearby. Chamomile’s cheerful flowers also attract pollinators.

  • Name: Chamomile (Matricaria recutita, Chamaemelum nobile)

  • USDA Hardiness Zones: 2-9

  • Light: Full sun

  • Soil: Well-drained, neutral

    Marigolds are incredibly unfriendly to pests, which is exactly why you want them in your garden. They repel nematodes and attract ladybugs and parasitic wasps, which will promptly rid your garden of the aphids and beetles that threaten basil.

  • Name: Marigold (Tagetes spp.)

  • USDA Hardiness Zones: 2-11

  • Light: Full sun

  • Soil: Evenly moist, well-drained, slightly acidic to neutral

    Basil does much of the heavy lifting in the relationship with peppers, where it traps in the moisture and humidity that peppers need to thrive. The pollinators that basil attracts also pollinate the peppers, while repelling pests.

  • Name: Pepper (Capsicum annuum)

  • USDA Hardiness Zones: 9-11

  • Light: Full sun

  • Soil: Fertile loam, neutral

  • Anyone who loves Italian cuisine knows that there’s nothing better than plucking a vine ripened tomato and fresh basil from the garden. But these two also do well in the same conditions and basil repels tomato hornworms.

  • Name: Tomato (Solanum lycopersicum)

  • USDA Hardiness Zones: 3-11

  • Light: Full sun

  • Soil:  Loamy, well-drained, neutral to acidic

    Because basil’s aromatic fragrance overpowers other scents nearby, it can be used to mask the scent of the greens that grow atop root vegetables. This keeps pests and predators away while the vegetables grow safely underground.

  • Name: Radish (Raphanus sativus)

  • USDA Hardiness Zones: 2-11

  • Light: Full sun

  • Soil: Loamy, sandy, moist, well-drained, acidic, neutral

    Carrots are particularly susceptible to aptly named carrot flies. But basil’s strong fragrance repels these and other pests from munching on carrots before they’ve been harvested.

  • Name: Carrot (Daucus carota)

  • USDA Hardiness Zones: 3-10

  • Light: Full sun to part shade

  • Soil: Loose, well-draining soil, slightly acidic

    Eggplant often falls victim to many of the same pests as tomatoes, including the tomato hornworm. Since basil repels the tomato hornworm, that makes eggplant and basil excellent companions in the garden.

  • Name: Eggplant (Solanum melongena)

  • USDA Hardiness Zones: 9b–12a

  • Light: Full sun

  • Soil: Loamy, well-drained, acidic, neutral, alkaline

    Aphids love lettuce. Hoverflies and parasitic wasps enjoy both aphids and the sweet taste of basil flower nectar. That means planting basil near lettuce will bring in the insects that control aphids and keep your lettuce safe and sound.

  • Name: Lettuce (Lactuca sativa)

  • USDA Hardiness Zones: 2a–11b

  • Light: Full sun to partial sun

  • Soil: Loamy, rich, well-drained, acidic, neutral

  • Name: Chives (Allium schoenoprasum)

  • USDA Hardiness Zones: 3-9

  • Light: Full sun to light shade

  • Soil: Loamy, sandy, slightly acidic to neutral

    Cilantro is easy to grow in a container or in your herb garden.

    Cilantro is another one of the aromatic herbs that can enhance the flavor of basil. These two herbs both require lots of sun and water so they grow well when planted next to each other.

  • Light: Full sun to partial sun

  • Soil: Loamy, moist, well-drained, acidic

  • Basil and garlic are the start of a great meal, and they also grow beautifully together in the garden. Garlic keeps away some of basil’s bigger enemies, like squirrels and rabbits, and the two enhance each other’s flavor.

  • Name: Turnip (Brassica rapa)

  • USDA Hardiness Zones: 2-9

  • Light: Full sun to partial shade

  • Soil: Sandy, well-draining, slightly acidic

  • Frequently Asked Questions

    Where does basil like to be planted?

    Basil likes to be planted somewhere it can get six to eight hours of sun a day. However, if it’s too hot, basil will wilt if it’s left in the beating afternoon sun. Basil also needs to stay moist throughout the day, so plant it somewhere that it will get morning dew or be ready to water it regularly.

    What herbs can I plant together?

    Generally, herbs should be planted near other herbs with similar growing requirements. That means Mediterranean herbs like sage, rosemary, and thyme should go together, while water-loving herbs like basil, parsley, dill, and mint grow well together.
