Can Tomatoes be Planted with Cucumbers: Tips for Your Vegetable Garden

A perfectly curated vegetable garden is a thing of beauty. One that is full of fresh, plump fruits and vegetables that are just begging to be eaten. But achieving this level of perfection takes time, patience, and a whole lot of know-how.

Additionally, when you’re working on your garden, space may be limited. This means that you have to be strategic about what you plant where and how close together you plant them. Tomatoes and cucumbers are two of the most popular vegetables to grow, so it makes sense that you would want to plant them together.

But is it possible, and can tomatoes be planted with cucumbers? Is it a good idea?

Companion plants grow well together, providing benefits to each other. In some cases, one plant might provide nutrients that the other needs. In other cases, one plant might act as a natural pest repellent for the other.

When it comes to cucumbers and tomatoes, these two vegetables can actually benefit from being planted together. They are perfect companion plants, and most gardeners have had great success growing them together.

Reasons Why Cucumbers and Tomatoes Go Well When Planted Together

Aside from the fact that these two vegetables often taste well when combined in salads and other dishes, there are reasons to believe they benefit each other when planted together. Here are some:


Cucumbers and tomatoes are both members of the nightshade family. This means that they are compatible with each other and will grow well together. They have similar growing requirements and will thrive in the same type of soil and climate.

Same Basic Needs

One of the primary reasons why these two vegetables do so well together is that they have the same basic needs. They both need full sun, well-drained soil, and consistent moisture.

Aside from these, they both thrive at the same pH level, which ranges from 5.8 to 6.5 pH. With that being said, planting them together makes sense. It’s more efficient and easier to take care of two plants that have the same needs than it is to take care of two plants with different needs.

Same Aversions

While there are what we call companion plants, some plants also don’t like to be planted near certain plants. For tomatoes and cucumbers, both hate being planted next to potatoes. Growing next to potatoes will stunt the growth of both tomatoes and cucumbers.

They also have the same aversions when it comes to certain chemicals. They are both susceptible to damage from herbicides that contain glyphosate. Glyphosate is known to kill plants by absorption through the leaves. It’s best to avoid using this type of herbicide if you’re growing these two vegetables together.

Pests and Diseases

Tomatoes and cucumbers are also both susceptible to the same pests and diseases. Some of the common ones are aphids, whiteflies, and tomato hornworms. They are also affected by the same diseases such as early blight, late blight, fusarium wilt, verticillium wilt, and mosaic virus.

By planting these two vegetables together, you can easily control pests and diseases. You can save time treating and putting in place preventative measures since you only need to do it once for both plants.

When it comes to pests and diseases, basil is a great companion plant for both cucumbers and tomatoes. Basil helps repel pests and can also help prevent diseases from spreading.

Planting basil alongside these two vegetables is a great way to provide some organic pest and disease control.


When it comes to harvesting, tomatoes and cucumbers are usually ready at the same time. This is another reason why it’s convenient to plant them together. You can harvest both vegetables at the same time and enjoy their freshness.

Tomatoes are typically mature once they reach a deep red color. You can also tell that they’re ripe when they start to soften. Cucumbers, on the other hand, are usually ready to be picked when they’re about six to eight inches long. They should also be a deep green color before you pick them.

Can Tomatoes be Planted with Cucumbers: Final Thoughts

A well-thought-out vegetable garden can provide you with a bountiful harvest of fresh and healthy vegetables. When planning your garden, it’s important to consider which vegetables grow well together.

Tomatoes and cucumbers are great examples of two vegetables that are compatible in many ways. They have the same basic needs, are affected by the same pests and diseases, and are usually ready to be harvested at the same time. Planting these two vegetables together can save you time and effort in your vegetable garden.
