What's a Good Companion Plant for Tomatoes?

Companion planting is a traditional method that maximizes agricultural productivity by planting different crops together so that they benefit each other. Tomatoes, one of the most popular garden vegetables, benefit from companion planting as well. In this article, we'll explore some of the best companion plants for tomatoes.

Basil

Basil and tomatoes are one of the most well-known and traditional companion plantings. Basil helps repel insects like flies, mosquitoes, mites, and aphids from tomatoes, while tomatoes provide shade and moisture for basil plants. Additionally, the sweet aroma of basil might enhance the flavor of the tomatoes.

Marigolds

Marigolds are excellent companion plants for tomatoes because they contain chemicals that repel harmful insects such as whiteflies, nematodes, and tomato hornworms. They also help improve soil quality, attract pollinators such as bees and butterflies, and add bright colors and beauty to your garden.

Borage

Borage, also known as starflower, is another great companion plant for tomatoes. Borage plants attract beneficial insects such as bees and hoverflies, which help pollinate tomato flowers and control pests such as tomato worms and cabbage moths. Additionally, borage leaves can be used as compost or green manure to improve soil quality.

Nasturtiums

Nasturtiums are edible flowers that not only add beauty to your garden but also provide numerous benefits for tomatoes. The flowers and leaves of nasturtiums contain a chemical that repels aphids and whiteflies, both common pests of tomatoes. They also attract beneficial predatory insects like ladybugs, which feed on aphids and other pests. Moreover, nasturtiums can be used in salads and other dishes to add a spicy, peppery flavor.

Peppers

Tomatoes and peppers are both members of the nightshade family and share similar soil and nutrient needs, making them perfect companion plants. Additionally, peppers contain capsaicin, a chemical that repels pests such as aphids, spider mites, and thrips, while tomatoes provide shade and support for pepper plants. However, be aware that planting peppers close to tomatoes might increase the chances of cross-pollination between the two crops.

In Conclusion

Companion planting is a simple and effective way to improve tomato yields, reduce pest damage, and enhance soil quality. While these are some of the best companion plants for tomatoes, there are many other options you can explore, including carrots, onions, and garlic. It's always a good idea to do some research and experiment with different companion plants to find the ones that work best for your garden.
