Looking for great tomato companion plants? This post gives you a list of great companion plants for tomatoes to grow together with tomatoes in your garden.

While we love to eat them fresh off the vine, tomatoes also play a starring role in salads, sandwiches, sauces, pizzas and so much more.

This popular fruit (yes, tomatoes are fruits!) is not only delicious but also easy to grow. Tomatoes come in a wide range of sizes, shapes, and colors, and there is sure to be a variety that will fit perfectly into your home garden.

Companion planting is a gardening technique that has been around for centuries. The basic idea is to plant complementary species of plants near each other so that they can share resources, provide pest control or improve pollination rates.

Many different companion plants can be used with tomatoes to improve yields, deter pests and attract beneficial insects. The following is a list of the best companion plants to grow with tomatoes:

The Best Tomato Companion Plants

Tomato companion plants can help improve the health and yield of your tomato plants. Companion planting is a form of intercropping that involves growing different plants together.

The plants can provide each other with shade, support, nutrients, and other benefits. Below are some companion plants for tomatoes.


Most gardeners know that tomatoes and basil are a classic pairing, but did you know that these two plants can actually help each other grow?

Tomatoes release a compound called methyl eugenol into the air, and basil responds by growing taller and producing more leaves. So not only do these two plants taste great together, but they can also give each other a boost!


Borage releases a substance that increases the level of calcium in the soil, which helps prevent blossom end rot in tomatoes.


Chives (Allium schoenoprasum) are among the best companion plants for tomatoes because they help to repel aphids, mites, and other pests that can damage tomato plants.

Chives also contain compounds that can improve the flavor of tomatoes when the two plants are grown together.

Chives are a member of the onion family and can be used as a culinary herb in salads, soups, and other dishes.


Garlic (Allium sativum) is an excellent companion plant for tomatoes (Solanum lycopersicum). It’s a member of the allium family, which also includes onions (Allium cepa), leeks (Allium porrum), and shallots (Allium ascalonicum).


Marigolds are one of the best tomato companion plants because they help to deter pests. Marigolds emit a strong smell that repels many common garden pests, including nematodes, whiteflies, and even rabbits.

In addition, marigolds help to attract pollinators like bees, which can help improve the yield of your tomato plants.


Nasturtiums (Tropaeolum majus) are a cheerful addition to the tomato patch, with their rounded leaves and bright flowers in shades of yellow, orange, and red.

Nasturtiums are easy to grow from seed and will self-seed freely if you let them. These annual plants are related to watercress and have a similar peppery flavor.

Nasturtiums are good companion plants for tomatoes because they attract aphids and other pests away from the tomato plants. They also help to repel cabbage white butterflies.


As a member of the mint family, oregano is known to be a vigorous grower. Like other mints, it can quickly spread through your garden if you don’t keep it in check.

Oregano also benefits from being trimmed back regularly to encourage new growth. When growing oregano alongside your tomatoes, make sure to give it plenty of room to spread.

Oregano is a strong herb with a robust flavor. A little goes a long way, so use it sparingly when cooking. When used fresh, oregano has a more delicate flavor than when it is dried.

Oregano is most commonly used in Mediterranean and Italian dishes, but it can also be used in soups, sauces, and salad dressings.


Mint is a vigorous grower that can quickly take over your garden if you don’t keep it in check. It has a strong flavor that should be used sparingly.

Mint can also help deter pests and improve the flavor of your tomatoes.


Parsley is a biennial herb in the family Apiaceae, or Umbelliferae, usually known in Britain as the flat-leaved or Italian parsley. It is a bright green, biennial, with curly leaves.

Originally from Mediterranean countries, parsley is now cultivated all over the world as a culinary herb. Parsley grows best in cool to temperate regions.

Parsley is used for garnish, as a flavoring agent, and as a dried herb. Fresh parsley leaves are the most commonly used part of the plant.

They are used chopped in salads, soups, and sauces; as a garnish; and as a flavoring agent for other dishes. The leaves can also be dried and used as an herb. The root can be cooked and eaten as a vegetable.


Rosemary (Rosmarinus officinalis) is an aromatic evergreen herb that produces small, pale blue flowers. It is native to the Mediterranean region and is a member of the mint family (Lamiaceae).

Rosemary is a popular culinary herb and can be used fresh or dried. It is also used in cosmetics and as an ingredient in some beauty products.

Rosemary grows best in full sun and well-drained soil. It is tolerant of drought and does not need very much water once it is established.

Rosemary can be propagated from seeds, cuttings, or divisions. It can also be grown in pots or containers.

Rosemary is often used as a companion plant for tomatoes (Solanum lycopersicum). The two plants benefit each other when they are grown together.

The rosemary helps to repel insects that might damage the tomatoes, and the tomatoes provide shade and help to keep the rosemary from getting too dry.


Thyme (Thymus vulgaris) is a hardy perennial that grows in the sun or part shade. It has small, Fragrant leaves and tiny lavender flowers that appear in summer. This slow-growing herb reaches a height of 12 to 18 inches (30 to 45 cm.) And a spread of 12 to 24 inches (30 to 60 cm.). Thyme is drought tolerant once established.

A member of the mint family, thyme is an ideal companion plant for tomatoes. It is said to repel cabbage worms, whiteflies, and other pests that can damage tomato plants.

When planted near tomatoes, thyme will also improve the flavor of the fruit. Thyme can be used fresh or dried in cooking. It is also a popular ingredient in many commercial tomato sauces and pizzas.
