Can You Plant Tomatoes And Beans Together?

Our experienced writers spend hours deep researching, considering both scientific and experimental info to bring the insights you can trust.  

Quick Answer: Can You Plant Tomatoes And Beans Together?

Tomatoes and beans are frost-sensitive plants that may thrive well as companions due to similar growing conditions. Pole beans may be grown on the same trellis as tomatoes. Bush beans may be interplanted between tomato plants. Tomatoes need nitrogen in the soil, and beans can fix nitrogens into the soil. Take care to balance the nutrient and fertilizer applications according to the requirement of both crops.

Are you wondering if we can plant tomatoes and beans together? If, yes, this guide will provide you with all the answers!

I have personally experimented with planting tomatoes and beans in my vegetable garden and had success.

Can You Plant Tomatoes And Beans Together?

Companion planting helps in increasing pollination, deterring pests, and improving flavor. Tomatoes may be compatible with beans due to similar growing conditions.

Companion planting involves planting two or more crops next to each other for the mutual benefit of each other. It may result in enhanced pollination, deterring pests, improving the flavor, higher yields, and better nutrition.

One of my favorite crops in the vegetable garden is tomatoes.

Several plants are considered good companions for tomatoes, including amaranth, asparagus, basil, nasturtium, marigold, onion family, parsley, sage, and carrots.

One of the less popular combinations is tomatoes and beans.

Many gardeners recommend planting them together as they thrive in similar environments.

Basic Requirements Of Tomatoes

Tomatoes are warm-season crops that require full sunlight, soil with acidic pH, and consistent watering of one to two inches per week. They may be determinate or indeterminate according to their growth habits.

Tomatoes grow well in well-drained sites and require sunlight for most of the day. It requires a slightly acidic pH. 

They are classified into determinate and indeterminate according to their growth habit. Determinate varieties grow to a certain height and set fruit within a limited time.

Indeterminate continues growing and producing fruits for a long time.

They require one to two inches of water per week during the growing season. They have a deep root system and need consistent watering.

They prefer watering at the base to reduce the incidence of diseases.

Basic Requirements Of Beans

Common beans are sensitive to frost and prefer warmer temperatures. They grow well in well-drained, loamy soil with acidic pH. They have shallow roots and prefer an inch of water per week.

Common beans are warm-season crops and may be planted after the danger of frost has passed.

Like tomatoes, they prefer a warmer soil temperature during transplantation. They grow well in full sunlight and fertile, well-draining, loamy soil with a pH of 6-6.75.

Like tomatoes, common beans can be either bush or pole varieties. Pole beans require a pole or trellis to climb. You may install support when transplanting them.

Common beans need an inch of water per week. You may use a drip irrigation system to avoid splashing on the leaves.

They have shallow roots and may require hoeing to control small weeds and grasses.

Growing Tomatoes And Beans Together – Does it Work?

Planting tomatoes with beans may save space. Bush beans may deter weeds around tomato plants and improve air circulation. Tomatoes may make use of nitrogen fixed by beans. They grow well together after adjusting watering and fertilizer supply.

As I mentioned above, tomatoes and beans share similar growing conditions and few nutritional requirements.

Therefore, they may be planted together if we can control nutrient and water needs. 

A scientific study showed that the intercropping of tomatoes and common beans did not harm each other and affect their yield. It also highlighted that it may provide economically profitable options for farmers.

Another study reported that bean-tomato intercropping reduced the potato leafhopper densities and their damage to bean leaves.

Bush Beans

I also use bush beans as tomato companions as they take up less space and are compact.

One added advantage of using bush beans is that it may deter the growth of weeds due to their dense growth habit. 

The bush beans may improve air circulation and reduce the susceptibility of tomato plants to diseases.

Beans & Tomato Spacing

The companion planting of tomatoes and beans may help in saving space. I interplant pole beans with tomatoes on a shared trellis.

I prefer to plant beans after the tomatoes are established. Otherwise, they may crowd the cage.

The spacing between tomatoes and bush beans depends on the variety.

But, allow enough spacing as bush beans may be shaded by the tomato plants.

Fertilizer Requirements when Planting with Beans

Beans host the nitrogen-fixing bacteria and fix nitrogen in the soil as legumes.

Therefore, they do not require any additional nitrogen fertilizers. They may produce huge bushy plants with little beans.

They make fewer demands on the nutrient supply of the soil and benefit from being mulched.

Tomatoes on the other hand require macronutrients, including nitrogen, phosphorus, and potassium for a variety of functions.

They may make use of nitrogen fixed by the beans in the soil. But the high nitrogen levels in the soil will result in high vegetative growth but lesser tomato fruits.

So, if you are planting tomatoes and beans together, use appropriate fertilizers and balance them out. Avoid using high-nitrogen fertilizers. 

Also, water the tomato plants without drowning the beans as tomatoes require more water.

Susceptibility To Diseases

Tomatoes and beans are susceptible to a variety of diseases and pests, including cutworms. Practice crop rotation and adequate pest control measures to avoid diseases.

Both tomatoes and beans are susceptible to a wide range of diseases and pests. One of the pests that attacks both beans and tomatoes is cutworms.

They curl their bodies around the stem of the plant and feed them. It causes the plant to be cut off.

You may follow appropriate pest control procedures. Also, I prefer to follow crop rotation.

I plant tomatoes and beans in a different location every year so that the diseases in the soil are not carried forward.

Also, protect both the crops from strong winds as it may affect the fruit yield.


Can you plant tomatoes and pole beans together

Yes. You may interplant tomatoes and beans on a shared trellis. However, this arrangement will work only if the beans are planted after the tomatoes are well established. It may be because the beans have extensive growth.

What will happen if you plant a tomato next to a bush bean?

If you grow a tomato plant next to a bush bean, it will be shaded by the tomato plant. So, you may have to plant them far enough from tomato plants facing the sun. This growing pattern may not affect the yield.


I hope with this guide, you would be able to decide whether you want to plant beans along with tomato plants or not.
