What you can grow with basil is a whole thriving garden of delicious companions, because basil is one of the best neighbor plants you can have.
When you grow with basil, you’re not just planting a single herb, you’re setting up a natural support system for many other vegetables, fruits, and flowers.
If you’ve been wondering what can you grow with basil that will actually benefit from its presence, the good news is that the list is longer than you might think.
Basil’s strong aromatic oils naturally repel many common pests, which is a huge reason why so many gardeners love to grow with basil as a companion.
In this post, we’ll explore the best plants you can grow with basil, why these pairings work so well, and which plants you should keep far away from your basil patch.
Let’s dig into the wonderful world of companion planting and see what can you grow with basil to make your garden healthier and more productive.
Why You Should Grow With Basil as a Companion
You can grow with basil to boost the health and flavor of nearby plants, and the science behind it is pretty cool.
Basil releases volatile oils, especially when its leaves are brushed or lightly disturbed, and these oils confuse and repel flying pests like aphids, mosquitoes, and whiteflies.
Many gardeners report that when they grow with basil, their neighboring crops suffer less pest damage and even seem to produce better yields.
Here are the main reasons why growing with basil is such a smart move for your vegetable patch.
1. Natural Pest Deterrent
The most famous benefit of basil is its ability to keep pests away without any chemicals.
Because basil is packed with aromatic compounds like estragole and linalool, it masks the scent of nearby crops from hungry insects.
If you’re wondering what can you grow with basil to reduce tomato hornworm issues, basil is your answer, as it’s especially good at repelling these destructive caterpillars.
You can grow with basil around your garden borders to create a fragrant barrier that many pests simply won’t cross.
2. Improved Flavor and Growth
Some gardeners believe that growing with basil actually enhances the flavor of certain crops, particularly tomatoes.
While this is partly anecdotal, the improved health from pest protection can definitely lead to more vigorous plants and tastier fruit.
Plus, basil attracts pollinators and beneficial insects like bees and parasitic wasps, which helps boost fruit set on nearby vegetables.
So when you ask what can you grow with basil, the answer often includes anything that relies on pollination, because more pollinators means better harvests.
3. Efficient Use of Garden Space
You can grow with basil in between larger plants to make the most of your available space.
Basil’s shallow root system means it won’t compete much with deep-rooted vegetables, making it a perfect interplanting partner.
It’s also great for filling in gaps in your beds, and as a bonus, you’ll have fresh basil within arm’s reach while you harvest your other veggies.
Best Vegetables You Can Grow With Basil
If you’re planning your garden and wondering what can you grow with basil, these vegetables are some of the most successful pairings.
Just about any garden staple can benefit from basil’s pest-repelling powers, but these are the ones that truly shine.
1. Tomatoes
This is the classic combination, and for good reason.
Tomatoes and basil are culinary soulmates, and they’re also fantastic garden partners.
You can grow with basil right at the base of your tomato plants to repel hornworms and improve the flavor of the fruit.
The two plants have similar water and sunlight needs, so they thrive together without much extra effort.
2. Peppers
Peppers are another nightshade family member that loves basil’s company.
Aphids and spider mites can be a real problem for peppers, but basil helps keep those pests at bay.
You can grow with basil between your pepper plants to create a living mulch that keeps the soil cool and moist.
This pairing also looks great in the garden, with the deep greens of both plants creating a lush backdrop.
3. Asparagus
Asparagus is known for attracting asparagus beetles, which can quickly defoliate the plant.
Basil is a natural deterrent for these beetles, so you can grow with basil alongside your asparagus bed for protection.
Plus, basil’s flowers will attract beneficial predators that feed on those beetles, giving you a double layer of defense.
4. Root Vegetables
Carrots, beets, and radishes all do well when you grow with basil nearby.
Since basil doesn’t take up much surface area, it can be sown in rows right next to your root crops.
Basil’s scent confuses carrot flies, which are a common pest that targets the roots of carrots and parsnips.
Herbs and Flowers to Grow With Basil
The list of what can you grow with basil extends far beyond just vegetables, as many herbs and flowers make excellent companions.
These plants can help you create a diverse and resilient garden ecosystem.
1. Marigolds
Marigolds are the ultimate companion flower, and they work beautifully alongside basil.
Both plants repel nematodes and various insects, so growing them together doubles your pest protection.
Marigolds also attract hoverflies, which are natural predators of aphids, making them a great partner for your basil.
2. Oregano and Rosemary
Mediterranean herbs like oregano and rosemary love the same sunny, well-drained conditions as basil.
You can grow with basil alongside these herbs to create a fragrant herb garden corner.
Not only do they look and smell amazing together, but they also repel many of the same pests, like cabbage moths and cucumber beetles.
3. Lettuce and Leafy Greens
If you’re thinking about what can you grow with basil to fill out your salad greens, lettuce is a solid choice.
Basil’s strong scent masks the smell of lettuce from slugs and other soft-bodied pests, and its shade can help keep the soil cool for these heat-sensitive greens.
Plants to Avoid Growing With Basil
Just as there are good companions, there are also a few plants that don’t play nicely with basil.
Knowing what not to plant is just as important as knowing what can you grow with basil.
1. Rue
Rue is a medicinal herb that actually inhibits the growth of basil.
It releases chemicals into the soil that can stunt basil’s development, so it’s best to keep them far apart.
2. Cucumbers and Squash
While it’s not a disaster, cucumbers and squash are heavy feeders that may compete with basil for nutrients.
More importantly, they are prone to powdery mildew, and dense plantings with basil can reduce airflow and increase humidity.
It’s better to grow with basil near other crops and give your cucurbits plenty of space.
3. Fennel
Fennel is known to be allelopathic, meaning it secretes compounds that can harm nearby plants, including basil.
Always plant fennel on its own, and don’t even think about pairing it with basil if you want healthy growth.
So, What Can You Grow With Basil?
You can grow with basil a wide variety of vegetables, herbs, and flowers, making it one of the most versatile companion plants in the garden.
So, what can you grow with basil is really a question with endless rewarding answers, from the classic tomato pairing to helpful marigolds.
Basil’s pest-repelling properties and ability to attract pollinators make it a must-have for any organic gardener.
Just remember to avoid planting it near rue, fennel, and overcrowded squash, and your basil and its neighbors will flourish together beautifully.
Hope this helps you plan a more productive, healthier, and more fragrant garden this season.
