Tomatoes are one of the most popular plants to grow in home gardens. They are not only delicious but also versatile in cooking. However, did you know that planting certain companion plants alongside your tomatoes can enhance their growth, deter pests, and improve overall garden health? In this article, we will explore some of the best companion plants for tomatoes and the benefits they bring to your garden.

Why Plant Companion Plants?

Companion planting is a gardening technique that involves growing different plants together to create a mutually beneficial environment. By carefully selecting companion plants, you can promote healthy growth, deter pests, attract beneficial insects, and improve soil fertility.

Best Companion Plants for Tomatoes

1. Basil: Planting basil near tomatoes helps repel pests like aphids and whiteflies. Additionally, the aroma of basil is known to enhance the flavor of tomatoes when cooked together. It’s a win-win situation for both plants and your taste buds!

2. Marigold: Marigolds are excellent companion plants for tomatoes as they deter harmful nematodes and repel other insects like aphids and whiteflies. Their strong scent acts as a natural insect repellent, creating a protective barrier around your tomato plants.

3. Nasturtium: Nasturtiums attract predatory insects like ladybugs and lacewings, which feed on common tomato pests like aphids and caterpillars. Planting nasturtiums near your tomatoes can help keep these harmful insects in check, reducing the need for pesticides.

4. Garlic: Garlic is well-known for its natural insect-repellent properties. Planting garlic near tomatoes can help deter pests like aphids, spider mites, and hornworms. Additionally, garlic improves the overall health of the soil by preventing the growth of harmful fungi and bacteria.

5. Onions: Onions are another great companion plant for tomatoes. They repel pests like aphids, thrips, and onion flies. Onions also help improve soil fertility and can act as a natural mulch, preventing weed growth around your tomato plants.

Companion Planting Tips

When planning your tomato garden, keep these companion planting tips in mind:

  • Plant companion plants around the perimeter of your tomato patch to create a barrier against pests.
  • Rotate your companion plants each year to prevent the buildup of pests and diseases.
  • Choose companion plants that have similar sun, water, and soil requirements as tomatoes.
  • Consider intercropping, where you mix companion plants in between your tomato plants, maximizing space and benefits.
  • Monitor your garden regularly for signs of pests or nutrient deficiencies and take appropriate action.


Companion planting is a valuable technique that can enhance the health and productivity of your tomato garden. By choosing the right companion plants, you can naturally deter pests, attract beneficial insects, and improve soil fertility. Experiment with different combinations of companion plants to find the ones that work best for your garden. Happy gardening!
