Tomatoes are one of the most popular garden vegetables, and pairing them with the right companions can make a huge difference. Here are some top picks:
Basil
Basil is the classic tomato companion. It repels aphids, whiteflies, and tomato hornworms while enhancing the flavor of nearby tomatoes. Plant basil 10-12 inches away from tomato plants.
Marigolds
Marigolds are natural pest deterrents. Their strong scent confuses and repels nematodes, aphids, and other insects. French marigolds (Tagetes patula) are particularly effective.
Carrots
Carrots loosen the soil around tomato roots, improving aeration and drainage. While carrots may be slightly stunted by the tomato canopy, both plants still benefit from the partnership.
Borage
This herb attracts pollinators and repels tomato hornworms. Borage also contains trace minerals that benefit soil health when it decomposes.
What to Avoid
Keep fennel, brassicas, and corn away from your tomatoes. Fennel is allelopathic to most vegetables, and corn shares many of the same pests as tomatoes.
