The Best Companion Plants For Basil

The top choices for what you can plant next to basil are tomatoes, peppers, and asparagus because they share similar care needs and offer mutual benefits.
 
Basil loves full sun, well-drained soil, and consistent moisture, so it pairs well with other warm-season crops that want the same growing conditions.
 
When you choose what you can plant next to basil, you also want to consider plants that repel pests or improve the flavor of your basil.
 
Here are the top companion plants that answer what you can plant next to basil:
 

1. Tomatoes Are The Classic Partner

Tomatoes are the most famous answer when asking what you can plant next to basil.
 
Basil helps tomatoes by repelling tomato hornworms, aphids, and whiteflies with its strong aromatic oils.
 
In return, tomatoes provide a bit of afternoon shade for basil during the hottest part of the day.
 
Many gardeners also say that basil improves the flavor of tomatoes when they grow side by side.
 
So if you want to know what you can plant next to basil for a productive summer harvest, tomatoes should be your first choice.
 

2. Peppers Love Basil’s Pest Control

Another great answer to what you can plant next to basil is any type of pepper, from bell peppers to hot chili varieties.
 
Basil repels thrips, spider mites, and mosquitoes that often bother pepper plants.
 
Peppers and basil have matching watering schedules, so you can easily care for them together in the same bed.
 
This pairing works whether you grow them in raised beds, containers, or directly in the ground.
 
When you are deciding what you can plant next to basil, peppers are a reliable and tasty option.
 

3. Asparagus Benefits From Basil’s Ground Cover

Asparagus is a less common but excellent choice when thinking about what you can plant next to basil.
 
Basil grows low and bushy, acting as a living mulch that shades the soil and keeps asparagus weeds down.
 
The strong scent of basil also confuses asparagus beetles that love to munch on young asparagus spears.
 
Because asparagus is a perennial, you can plant basil around it every spring for continuous protection.
 
So if you have a permanent asparagus bed, what you can plant next to basil includes this long-lived vegetable.
 

4. Lettuce And Greens Enjoy Basil’s Shade

For a quick answer to what you can plant next to basil, try loose-leaf lettuce, spinach, or arugula in the same bed.
 
Basil grows taller than these leafy greens, offering light shade that prevents them from bolting in midsummer heat.
 
The greens also don’t compete with basil for nutrients since they have shallow root systems.
 
Basil’s aroma can even mask the scent of greens, making it harder for slugs and snails to find them.
 
This makes leafy greens a fantastic choice for what you can plant next to basil in cooler parts of your garden.
 

5. Marigolds And Flowers For Pollination

If you’re open to flowers, marigolds are a primo answer for what you can plant next to basil.
 
Marigolds release a root chemical that kills nematodes in the soil, protecting basil’s roots.
 
Their bright blooms attract bees, butterflies, and other pollinators that help basil flower and set seed.
 
Other flowers like borage and chamomile also work well when deciding what you can plant next to basil.
 
These flowering companions not only boost basil’s health but also add beauty to your garden.
 

What NOT To Plant Next To Basil

While many plants make great neighbors, there are a few things you should avoid when figuring out what you can plant next to basil.
 
Basil prefers slightly acidic soil, around pH 6.0 to 7.0, which limits some partners that need alkaline conditions.
 
Certain herbs and vegetables just don’t get along with basil, and planting them together can stunt growth.
 

1. Rue And Sage Compete With Basil

Rue is a classic bad neighbor basil does not tolerate well.
 
Sage also competes with basil for the same nutrients and tends to slow down basil’s growth.
 
Both rue and sage prefer drier soil, while basil demands more consistent moisture.
 
So when you ask what you can plant next to basil, make sure you keep rue and sage in separate beds.
 

2. Fennel Inhibits Basil’s Growth

Fennel is a notorious garden bully that secretes chemicals that stunt the growth of nearby plants.
 
If you plant fennel next to basil, your basil may turn yellow and struggle to produce leaves.
 
So crossing fennel off your list of what you can plant next to basil is a smart move.
 
Keep fennel isolated in its own corner of the garden, far away from your basil patch.
 

How To Arrange Basil With Its Companions

Now that you know what you can plant next to basil, it’s time to think about how to arrange them in your garden.
 
Basil grows about 12 to 24 inches tall, so place it in front of taller plants like tomatoes.
 
For bushier crops like peppers, tuck basil between them to fill gaps and maximize your space.
 
Always leave at least 12 inches between basil and its companions so both have room to breathe.
 
Water deeply and evenly because basil and its companions all dislike dry spells.
 
You can also interplant basil throughout your vegetable rows to create a natural pest barrier.
 
If you’re using containers, choose a large pot that can hold basil and one or two companion plants together.
