Companion planting is a fantastic way to improve your garden’s overall well-being by strategically pairing plants that benefit each other. One such superstar in the world of companion plants is basil. This aromatic herb not only brings its signature flavor to dishes but also offers a range of benefits for its plant neighbors. In this article, we’ll explore the top basil companion plants and tips to create a thriving garden.

Top Basil Companion Plants


When it comes to basil and tomatoes, it’s a match made in garden heaven! These two plants have a fantastic mutualistic relationship. Basil helps improve tomato growth and flavor while also acting as a natural pest repellent.

Growing basil alongside your tomatoes can help keep pests like aphids, hornworms, and whiteflies at bay.

Plus, you’ll love the convenience of having these two essential ingredients for your favorite pasta sauces and salads right next to each other in your garden!


Peppers and basil are another dynamic duo in the garden. The strong aroma of basil can help enhance the flavor of peppers, while acting as an organic pest control for peppers by repelling things such as spider mites and aphids.

Both peppers and basil have similar cultural requirements, which makes them great companions in the garden. They both love full sun and well-drained soil, so planting them together can help ensure a healthy, flavorful harvest.


Lettuce is one of the best basil companion plants because it benefits from the shade provided by the taller basil plants. This shade helps lettuce maintain its moisture, preventing it from bolting in the summer heat.

Planting basil and lettuce together also makes excellent use of garden space. The low-growing lettuce can fill in the gaps between taller basil plants, reducing weed growth and creating a lush, green garden bed.

Trust me, your garden will look amazing, and your salads will taste even better!


Marigolds are not only beautiful, but they’re also fantastic basil companion plants. These vibrant flowers deter a range of garden pests, including nematodes and tomato hornworms, which can wreak havoc on your precious basil and tomato plants.

As an added bonus, marigolds attract beneficial insects like ladybugs, which help control aphid populations. Plus, the bright colors of marigolds will add a lovely splash of color to your garden. Who wouldn’t want a beautiful and healthy garden?


Oregano and basil make excellent companions in both the garden and the kitchen. Their complementary flavors enhance each other, making them a go-to combo for Italian dishes.

In the garden, oregano helps deter pests like cabbage moths, while its deep root system can help improve soil structure. This mutually beneficial relationship allows both herbs to flourish, providing you with a bountiful harvest for your favorite recipes.

You can even grow oregano in containers which can be placed around the garden.

Tips for Successful Basil Companion Planting


Proper spacing

When planting basil and its companions, it’s essential to provide enough space for each plant to grow and thrive. Overcrowding can lead to poor air circulation and increased risk of disease. Be sure to follow the recommended spacing guidelines for each plant, and your garden will flourish!

Crop rotation

Crop rotation is vital for maintaining soil health and preventing the build-up of pests and diseases. Rotate your basil and its companion plants with different plant families each year to keep your garden thriving and healthy. Trust me; this simple step will make a huge difference in the long run.

Soil preparation

A well-prepared soil is the foundation of a successful garden.

Before planting your basil and its companions, make sure to amend the soil with organic matter, like compost or well-rotted manure.

This will improve soil structure, drainage, and nutrient availability for your plants.

Watering and fertilization

Basil and its companion plants typically have similar water and nutrient requirements, making their maintenance much more manageable.

Be sure to water your plants regularly, especially during dry spells, and provide a balanced fertilizer to encourage strong growth and healthy, flavorful leaves.

BONUS TIP: Did you know you can grow basil from cuttings. When harvesting basil, you can propagate more plants from stems with at least four leaves.

Additional Basil Companion Plants


Beans are great basil companion plants because they help fix nitrogen in the soil, providing essential nutrients for basil and other neighboring plants. Plus, basil’s strong aroma can help repel pests that might be attracted to your bean plants.


Cucumbers can also benefit from being planted near basil. The basil plants help repel common cucumber pests like cucumber beetles, while the cucumber’s large leaves provide some shade for the basil during hot summer days.

Just keep in mind that basil could influence the flavor of the cucumbers.


Strawberries and basil might seem like an unlikely pair, but they can make great companions in the garden. Basil helps to deter pests like slugs and aphids that love munching on strawberry plants. Plus, you might be surprised by how well their flavors complement each other in dishes like fruit salads and smoothies!


Similar to lettuce, spinach can benefit from the shade provided by taller basil plants. Planting them together helps to maintain soil moisture, which is crucial for healthy spinach growth. The combination of basil and spinach also makes for delicious salads and pasta dishes.

Plants to Avoid Near Basil



As tempting as it might be to plant all your herbs together, mint and basil are not good neighbors. Mint can be invasive and may compete with basil for space and nutrients, leading to weaker basil plants.


Rue, an herb often used for medicinal purposes, should not be planted near basil. These two plants can inhibit each other’s growth, resulting in a disappointing harvest for both.


Although sage and basil are both popular herbs, they’re not ideal companions in the garden. Sage prefers drier soil conditions, while basil thrives in moist soil. Planting them together may result in one or both plants suffering from inadequate growing conditions.


Brassicas, such as cabbage, kale, and broccoli, are not recommended as basil companion plants. They have different soil nutrient requirements and can compete with basil for essential nutrients, leading to weaker plants and a smaller harvest.


Companion planting with basil can significantly improve your garden’s health and yield, and add a burst of flavor to your favorite dishes. By carefully selecting the best basil companion plants and following our helpful tips, you’ll create a thriving garden that will be the envy of your friends and neighbors.

So, go ahead and experiment with these combinations, and don’t forget to share your experiences and suggestions with fellow gardeners. Happy gardening!
