The Perfect Pair: Tomatoes and Beans Companion Planting

tomatoes and beans companion planting

When it comes to growing vegetables, many gardeners choose to plant tomatoes and beans together. The combination of these two plants is known as companion planting. This method aims to achieve a mutually beneficial relationship between the plants, resulting in better yields and healthier crops. In this blog post, we'll explore the benefits of planting tomatoes and beans together, how to properly plant them, and some tips for maintaining a successful harvest.

Benefits of Tomatoes and Beans Companion Planting

There are several advantages to planting tomatoes and beans together. Here are a few:

Nitrogen Fixation

Beans are nitrogen-fixing plants, which means they have the ability to take nitrogen from the air and convert it into a form that can be used by other plants. Tomatoes, on the other hand, require a lot of nitrogen to grow. By planting beans alongside tomatoes, the beans will provide the necessary nitrogen for the tomatoes, resulting in a healthier crop.

Pest Control

Companion planting can also help control pests. For example, planting marigolds alongside tomatoes can help repel harmful insects like nematodes. Additionally, beans attract beneficial insects like ladybugs and lacewings, which can help control aphids and other harmful pests.

Space Saving

By planting tomatoes and beans together, you can save space in your garden. Rather than having to dedicate separate areas for each plant, you can plant them side by side. This can be particularly useful if you have a small garden or limited space.

How to Properly Plant Tomatoes and Beans Together

Now that you know the benefits of companion planting tomatoes and beans, let's talk about how to properly plant them together.

Choosing the Right Varieties

When selecting your tomato and bean varieties, it's important to choose plants that have similar growing requirements. For example, both plants prefer well-drained soil and full sun. Additionally, it's important to choose bean varieties that are bushy rather than vining, as they will take up less space in your garden.

Preparing Your Soil

Before planting your tomatoes and beans, it's important to prepare your soil. This can be by tilling or digging the soil to a depth of at least six inches. You should also amend the soil with compost or other organic matter to improve its nutrient content.

Planting Your Seeds

When planting your seeds, it's best to plant the beans first. This will allow them to establish themselves before the tomatoes grow larger. Plant the beans about two inches apart, and then plant the tomatoes about 18-24 inches away from the beans. Be sure to plant the tomatoes deep enough so that only the top few leaves are above ground.

Tips for Maintaining a Successful Harvest

Once your tomatoes and beans are planted, there are a few things you can do to ensure a successful harvest:


Both tomatoes and beans require consistent moisture to grow. Be sure to water your plants regularly, especially during hot, dry weather.


In addition to the nitrogen provided by the beans, you may need to fertilize your plants throughout the growing season. Use a balanced fertilizer that is high in phosphorus to encourage fruit production.


Tomatoes require regular pruning to encourage healthy growth and fruit production. Remove any suckers that grow between the main stem and the branches, and remove any leaves that are touching the ground.

Companion planting tomatoes and beans can be a great way to maximize your garden space and improve your overall harvest. By choosing the right varieties, preparing your soil properly, and following some simple maintenance tips, you can enjoy a bountiful crop of healthy, delicious vegetables.


Q: Can I plant other vegetables alongside tomatoes and beans?

A: Yes! Companion planting can be with many different types of vegetables. Some popular combinations include cucumbers and radishes, carrots and onions, and peppers and basil.

Q: Do I need to use pesticides when planting tomatoes and beans together?

A: Not necessarily. Companion planting can help control pests naturally, but if you do encounter an infestation, you may need to use organic pesticides to protect your plants.

Q: How often should I water my tomato and bean plants?

A: Tomatoes and beans require consistent moisture to grow, so it's important to water them regularly, especially during hot, dry weather. Aim to water your plants at least once a week, or more frequently if needed.

Q: Can I plant tomatoes and beans in containers?

A: Yes! Tomatoes and beans can be grown successfully in containers as long as the container is large enough and has good drainage. Be sure to choose bush beans rather than vining varieties to save space.

Q: Can I save seeds from my tomatoes and beans for next year's garden?

A: Yes! You can save seeds from both tomatoes and beans for next year's garden. Just be sure to properly dry and store the seeds in a cool, dry place.
