The 20 Best Companion Plants Of Tomato

The scientific name for tomato plants in Latin is Solanum Lycopersicum. Tomato plants belong to Solanaceae, also known as the Nightshade family. The Solanaceae plant family also contains potatoes, eggplant, bell peppers, and chili peppers. In general, aromatic culinary herbs are suitable partners for nightshades such as tomatoes, although brassicas (members of the cabbage family) can hinder tomato plant growth.

Furthermore, the following plants are The 20 Best Companion Plants Of Tomato

1 . Sunflowers

Sunflowers are lovely garden companions because they bring beneficial insects and plants like bumblebees and birds. The sunflowers in the garden draw in the native bees, which in turn help pollinate the nearby self-fertile tomato blossoms. When it comes to the garden, these plants are not only tomato-friendly but also compatible with the vast majority of other vegetables.

2. Basil

Because basil’s aroma blends in, it is a great plant to grow alongside tomato plants. Pests like thrips and moths can’t find the plant and attack it when the aroma of the plant is concealed. Pests called thrips to love to devour tomato plants and propagate the Tomato Spotted Wilt Virus. Similar to tomato hornworms, which devour the plant and can ruin a harvest, adult moths lay hornworm eggs.

Pests, including mosquitoes, flies, and fruit flies, are also deterred from approaching tomato plants by basil. Additionally, basil can improve the flavor and encourage the development of tomato plants. Genovese basil and giant basil are two common basil varieties to plant next to tomatoes.

3. Carrots

Carrots make excellent companion plants because, when allowed to blossom, they attract beneficial parasitic wasps. As a biennial plant, flowering is more prevalent with overwintered carrots; therefore, try leaving some carrots in your garden beds over the winter. During the second summer, you will be able to pick seeds from the carrots when they bloom.

4. Beans

Beans are excellent companion plants for tomato plants because they attract bumblebees. Large native bumblebees are good garden pollinators. Plants are drawn to tomato blooms by bean flowers.

Self-fertile tomato blooms must be jiggled to release pollen for pollination. Wind, a gardener, or bumblebees can shake flowers for pollination. In sheltered yards, inviting bumblebees to tomato plants can aid with pollination.

5. Thyme

Thyme protects tomato plants from Armyworm Moths, a frequent pest in gardens in the Southeast. Eggs are laid by the moths on plants, and as they develop, the eggs become larvae (Yellow Striped Armyworm), which consume the plants (leaves, fruits, etc.).

The fact that thyme plants are relatively short makes them ideal for use as a living mulch or groundcover at the base of tomato plants. Thyme, a living groundcover, can stop rainwater from splashing onto tomato leaves and dispersing diseases that are carried by the soil.

6. Asparagus

One of the most well-liked tomato companion plants is asparagus. Nematodes that are poisonous and can affect the roots of tomato plants are repelled by asparagus. Asparagus plants also benefit from tomatoes because the smell of tomato plants deters asparagus pests.

7. Marigold

Marigolds, which are effective in discouraging nematodes, make excellent companion plants. Microscopic nematodes, which resemble worms, feed off the roots of tomato plants, especially in the warm, sandy soils ideal for growing tomatoes.

Planting marigolds near tomato plants can help prevent whitefly infestations. They may also attract beneficial insects like hoverflies and parasitic wasps as they protect against pests.

Grow with French marigolds to repel whiteflies. Basil, parsley, chives, alliums, nasturtiums, and asparagus are all great companion plants for tomatoes. Matt Biggs’s The Whole Guide to Fruits and vegetables

8. Parsley

Parsley is a great plant to grow with tomatoes because it attracts ladybugs. Ladybugs eat pests like hornworms that eat tomato plants. Also, parsley brings in hoverflies that eat aphids so that aphids won’t bother your tomato plant. You should also plant parsley near your tomatoes because it is often used in the same dishes.

9. Garlic

When planted next to tomato plants, garlic can deter spider mites from damaging them. These plants’ potent aroma can repel common flying problem insects.

Planting garlic in the fall and keeping it in the garden throughout the winter ensures a harvest as early as possible in the summer. When the garlic plants are at their most fragrant, just before harvest, they are most effective at warding off insects that lay their eggs in the spring.

10. Peppers

Because of their shared environmental preferences, peppers and tomato plants make excellent plants. These two nightshade plants go well together in the garden. These plants are susceptible to several soil-borne diseases, so growing them together simplifies annual crop rotation. Rotate your peppers and tomatoes around the garden together.

11. Chives

Because of the sulfur-based oils in chives, they make excellent tomato companion plants. Use these powerfully perfumed oils to protect your tomato plant from pests. In addition, chives are a great complement to any recipe that features tomatoes because of how they enhance the natural tomato flavor. Finally, chives’ spring blossoms are a magnet for bees, bringing an influx of much-appreciated insects to your yard.

12. Onion

Onions and other members of the allium family (garlic, green onions/scallions, chives) repel aphids, keeping them away from nightshade plants such as tomatoes, peppers, and potatoes. Onions also take a long time to develop, so they’ll be there with your tomatoes even throughout the long, hot days of July.

13. Cowpeas

Cowpeas are a great companion plant for tomato plants because they confuse and attract the pest green stink bug. Cowpeas attract green stink bugs, which prefer cowpeas to tomato plants, and should be planted away from tomatoes in southern gardens.

Check the cowpeas frequently to keep your tomato plants safe, and remove any green stinkbugs you find. After that, immerse them in a bucket of soapy water.

14. Nasturtium

Nasturtium is an edible flowering plant often used as a “trap” companion plant to attract aphids, keeping them away from your tomato plants. The peppery scent can also deter pests like whitefly and certain beetles. Lastly, these plants grow very quickly from seed and sprawl all over the ground, helping to keep the soil moist and providing a habitat for beneficial predator insects like spiders.

15. Lettuce

Tomatoes benefit from lettuce as a companion plant because of the lettuce’s size, shape, and culinary versatility. Lettuce is commonly planted in the shade of large tomato cages because tomatoes thrive in warm weather, whereas lettuce tends to bolt (prematurely develop seeds). To prevent weeds from taking root, lettuce can be planted in the vacant soil area around the tomato plants’ bases (weeds LOVE to find and colonize bare soil).

16. Celery

Celery is an ideal companion plant for tomato plants since it helps reduce soil-borne diseases and stimulate tomato plant growth. It is also convenient to keep on hand because it is used in many of the same recipes. Finally, because celery has unique watering and care requirements, you will frequently be in that garden section, making it easy to check on and tend to the tomato plants.

17. Cucumbers

tomatoes and cucumbers can be grown together. however, cucumbers can be grown at the base of tomato plants to suppress weeds. These two plants both love warm summer weather and will thrive in the same area of the garden. First, erect a trellis for the cucumbers to climb behind the tomato plant. Then, arrange the trellis on the northern side of the garden so that it does not provide shade to the tomato plant on bright days. Some cucumber vines will climb the trellis, while others may shade the ground around the tomato plant’s base.

18. Radishes

Radishes are a favorite crop of insect pests such as flea beetles, and their presence may deter them from eating tomatoes. Flea beetles consume the leaves of various vegetable plants (pumpkins, peppers, tomatoes, kale, squash, etc.), but they prefer radishes and will consume the radishes’ leaves instead. Radishes can be planted year-round in warm locations or late summer when temperatures are very high during midsummer.

19. Cilantro

Cilantro is effective against tomato hornworms and other voracious pest larvae. If the plants are allowed to bloom, the cilantro attracts and sustains parasitic wasps (the wasps eat the nectar). These wasps lay their eggs within tomato hornworms, which perish after their larvae develop into adulthood.

In addition, if you want to prepare hot summer foods such as fresh guacamole and pico de gallo, it is ideal to have cilantro close by your tomatoes. You’ll have your garden of salsa!

20. Peas

Peas are an excellent companion plant to put before tomatoes. Since peas are a cool-season crop, they are planted considerably earlier in the spring than tomatoes, warm-season produce. Since both plants require some type of vertical support, peas can be substituted for tomato plants when the temperature is too warm for peas to grow.

Additionally, peas are legumes that pull nitrogen from the air into the soil. As immature tomato plants grow their leaves, nitrogen is a crucial macronutrient. These leaves are necessary for photosynthesis and energy absorption, producing tasty tomatoes later in the season.

FAQs

What should not be planted around tomatoes?

The Brassica family, which includes plants like broccoli and cabbage, should not be grown next to tomatoes. Another undesirable crop is corn, which can attract tomato fruit worms and corn earworms. When tomatoes and potatoes are planted together, kohlrabi stunts tomato growth and increases the risk of potato blight. 

Can peppers and tomatoes be planted together?

It is possible to grow them effectively together since their needs are so similar. Infectious bacterial spots and Verticillium wilt are two diseases that can affect both tomatoes and peppers.

 Can cucumbers be planted next to tomatoes?

Tomatoes and cucumbers make great greenhouse companion plants since they flourish together in warm conditions. Similar amounts of time are required for them to germinate, water, and develop to maturity.

Can you plant potatoes and tomatoes together?

Potatoes are part of the same nightshade plant family as tomatoes, capsicum, or peppers; hence, these do not make excellent planting companions for potatoes. They will fight over the same soil resources if you plant them next to each other. They should be kept far apart because of the ease with which pests and diseases could spread from one to the other.
