In this post, we’ll explore what to plant with tomatoes and basil for a thriving, healthy garden that maximizes space and yields.
Let’s dig into the perfect garden companions for these beloved plants.
Why Plant Tomatoes and Basil Together?
Tomatoes and basil are more than just culinary soulmates; they’re garden superstars when planted side by side.
When you plant tomatoes and basil together, the basil acts as a natural pest deterrent, keeping annoying insects like aphids, spider mites, and tomato hornworms away from your precious tomato plants.
The strong aroma of basil confuses pests looking for tomatoes, making it harder for them to locate their favorite snack.
Plus, many gardeners swear that basil enhances the flavor of tomatoes, making them sweeter and more vibrant when they ripen.
So, if you’re planning what to plant with tomatoes and basil, starting with each other is your first smart move.
Beyond pest control, these two thrive in the same soil conditions and sunlight needs, making them perfect roommates.
1. Basil Improves Tomato Growth and Taste
Basil is a fantastic companion because it doesn’t just sit there; it actively works to improve your tomato plants’ health and taste.
The essential oils in basil are known to repel harmful insects, and some studies suggest these oils can even inhibit the growth of fungal spores that cause blight.
When you plant tomatoes and basil together, you’re creating a mini ecosystem where basil acts as a shield, reducing the need for chemical pesticides.
The flavor enhancement is a bonus that home cooks absolutely love, as tomatoes picked from these pairings seem to have a richer, more complex taste.
2. They Share Similar Growing Needs
Both tomatoes and basil are sun-worshippers that love warm weather and well-drained soil rich in organic matter.
They need at least six to eight hours of direct sunlight daily, and they both prefer slightly acidic to neutral soil with a pH between 6.0 and 7.0.
This makes what to plant with tomatoes and basil an easy answer because you won’t have to create different zones in your garden for them.
Watering is also simple, as both appreciate consistent moisture but hate waterlogged roots, so a good mulch layer helps keep them happy.
3. Space Efficiency Maximizes Your Garden
Basil is a relatively compact plant, so it fits neatly between tomato plants without competing for root space.
Tomatoes grow tall and upright, while basil stays low and bushy, making them perfect companions in the same bed.
This vertical layering means you can grow more food in less space, which is a huge win for small gardens or container gardening.
So, when you’re figuring out what to plant with tomatoes and basil, know that the basil fills the gaps beautifully.
What to Plant With Tomatoes and Basil: Top Companion Herbs
Besides basil, several other herbs make excellent companions for your tomato patch.
These herbs can enhance flavor, repel pests, and attract beneficial insects that pollinate your garden.
If you’re expanding your garden and wondering what to plant with tomatoes and basil, consider these aromatic additions.
1. Parsley
Parsley is a fantastic companion that attracts hoverflies and predatory wasps, which feed on aphids and other tomato pests.
It grows well in the same conditions as tomatoes and basil, and it doesn’t compete aggressively for nutrients.
Plus, having fresh parsley on hand for your pasta sauces is a culinary win.
2. Oregano
Oregano is a tough, low-growing herb that acts as a living mulch, helping to retain soil moisture and suppress weeds.
Its strong scent also repels cabbage moths and cucumber beetles, keeping your tomato plants safer.
Oregano and basil together create a powerful aromatic barrier that confuses a wide range of garden pests.
3. Chives
Chives are wonderful for tomato gardens because their onion-like smell repels aphids, mites, and even Japanese beetles.
They also improve the flavor of tomatoes, much like basil does, and they come back year after year.
Planting chives near your tomatoes and basil adds another layer of protection and culinary delight.
4. Marigold (Yes, It’s an Herb for Pest Control)
While not a culinary herb, marigold is often grouped with herbs for its pest-deterring properties.
The bright flowers attract beneficial insects, and their roots release compounds that kill harmful nematodes in the soil.
So, when planning what to plant with tomatoes and basil, definitely include a few marigolds as a colorful and functional companion.
What to Plant With Tomatoes and Basil: Best Vegetables and Flowers
Beyond herbs, there are several vegetables and flowers that make excellent neighbors for your tomato and basil duo.
These plants can improve soil health, attract pollinators, or provide a bit of shade for the soil.
Let’s look at the top contenders for what to plant with tomatoes and basil.
1. Carrots
Carrots are a great companion because they help break up the soil with their taproots, allowing water and air to penetrate deeper for tomatoes.
They also grow underground, so they don’t compete for above-ground sunlight, making them perfect space-savers.
The dill-like scent of carrot tops can even help repel some tomato pests.
2. Onions and Garlic
Alliums like onions and garlic are powerful pest deterrents due to their pungent sulfur compounds.
They repel aphids, spider mites, and even rabbits and deer in some cases.
Planting them around your tomatoes and basil creates a strong aromatic shield that most pests hate.
3. Borage
Borage is a beautiful flowering herb that attracts pollinators and beneficial predatory insects.
It’s also said to improve the flavor of tomatoes and deter tomato hornworm caterpillars.
Its bright blue flowers are a stunning addition to any garden, and it’s a great answer to what to plant with tomatoes and basil.
4. Lettuce and Spinach
Fast-growing leafy greens like lettuce and spinach can be planted in the shadow of your tall tomato plants.
They appreciate the partial shade provided by tomato foliage, especially in the heat of summer.
And as a bonus, they give you an early harvest while your tomatoes are still growing.
What NOT to Plant With Tomatoes and Basil
While there are many great companions, some plants should stay far away from your tomato and basil patch.
These plants can compete for nutrients, attract pests, or inhibit each other’s growth.
Knowing what to plant with tomatoes and basil also means knowing what to avoid.
1. Fennel
Fennel is a notorious companion plant enemy for tomatoes because it releases chemicals that inhibit tomato growth.
It also attracts pests that can damage your tomatoes, so it’s best to keep fennel in a separate corner of your garden.
2. Cabbage Family (Brassicas)
Plants like cabbage, broccoli, and kale compete heavily with tomatoes for nutrients and space.
They also attract pests like cabbage loopers that can spread to your tomatoes.
Keep these heavy feeders out of the same bed as your tomatoes and basil.
Final Tips for Companion Planting
Now that you know what to plant with tomatoes and basil, let’s wrap up with a few practical tips for success.
Always rotate your crops each year to avoid soil-borne diseases and nutrient depletion.
Give your plants enough space to breathe, ensuring good air circulation to prevent fungal issues.
