Best and Worst Companion Plants for Tomatoes

Posted on May 11, 2020May 11, 2020

Good Tomato Companion Plants

A lot of plants are touted as improving the health, vigor, and flavor of tomatoes. All of these features are hard to measure, little scientific research has actually been done to back up the claims, and many other factors may be involved. Still, it is interesting to try them out in your own garden.

Plants recommended for companion planting with tomatoes include amaranth, asparagus, basil, bean, borage, calendula (pot marigold), carrots, celery, chive, cleome, cosmos, cucumber, garlic, lemon balm, lettuce, marigold, mint, nasturtium, onion, parsley, peas, sage, stinging nettle, sow thistle, and squash.

  • Amaranth helps repel insects.
  • Basil repels insects and disease, improves growth and flavor. Repels mosquitoes and flies (even fruit flies).
  • Borage improves growth and flavor and repels tomato worms.
  • Bee balm, chives, dill, mint, and parsley improve health and flavor. Use dill early since mature dill starts to inhibit tomato growth.
  • Carrots planted near tomatoes may not get as large as they should, but they will still taste good.
  • Garlic repels red spider mites. Garlic sprays help control late blight.
  • Stinging nettle nearby improves taste.
  • Sow thistle aids growth.

Bad Companions for Tomatoes

  • Cabbage (Brassica) family: All relatives of cabbage stunt the growth of tomato plants (including broccoli, Brussels sprouts, cabbage, collards, cauliflower, kale, kohlrabi, rutabaga, and turnip).
  • Corn: The corn earworm is the same as the tomato fruitworm. (Also known as the cotton bollworm.) Growing the plants in proximity that are susceptible to the same pests can invite disaster and a decimated garden.
  • Dill: Mature dill plants, as mentioned above, will start to inhibit tomato plant growth. Plant the dill you want to go to seed away from your tomatoes.
  • Eggplant, peppers, and potatoes: These plants are in the nightshade family like tomatoes and are all susceptible to early and late blight, which will build up in the soil and get worse each year. Avoid planting them near each other or in place of each other for at least three years. Also, planting tomatoes near potatoes can make the potatoes more susceptible to potato blight.
  • Fennel: Fennel secretes a substance from its roots that inhibits tomato plant growth. This secretion affects many other garden plants, too.
  • Walnuts: Do not plant tomatoes under walnut or butternut trees, which produce an allelopathic chemical called juglone that inhibits the growth of tomatoes (and all the members of the nightshade family). Tomatoes are also susceptible to the disease walnut wilt.

Tomatoes Can Help These Plants

  • Asparagus: Tomatoes repel the asparagus beetle.
  • Gooseberries: The scent from interplanted tomatoes helps repel insect pests.
  • Roses: Tomatoes can protect roses from black spot. You can interplant or use a spray. To make a spray, liquify tomato leaves and then dilute them with 4 to 5 pints of water. Add a tablespoon of cornstarch. Use the spray on rose leaves, if you cannot plant tomatoes next to them. Some believe that It could be the cornstarch that does the trick here.
