When it comes to gardening, many people are familiar with the concept of companion planting. This is where two or more plant species are planted together in order to benefit each other in some way. One popular combination is cucumbers and tomatoes. In this article, we'll explore why these two plants make such great companions, as well as some tips for getting the most out of your cucumber and tomato garden.

Why Cucumbers and Tomatoes Are Great Companion Plants

There are several reasons why cucumbers and tomatoes make great companion plants. For one thing, they have very different root systems. Cucumbers have shallow roots that spread out horizontally, while tomatoes have deep roots that go straight down. This means that the two plants don't compete for nutrients in the soil, which can help both of them grow better.

Another reason why these two plants work well together is that they have different growing habits. Tomatoes are tall and narrow, while cucumbers are low and bushy. This means that they don't shade each other too much, which can also help with growth. Additionally, cucumbers can help keep pests away from tomatoes, as they are known to repel certain insects.

How to Grow Cucumbers and Tomatoes Together

If you want to try growing cucumbers and tomatoes together, there are a few things you should keep in mind. First of all, make sure you give each plant enough space. Cucumbers should be planted about 12 inches apart, while tomatoes should be spaced at least 24 inches apart. This will help ensure that they don't compete too much for resources.

You should also make sure to provide plenty of support for your tomato plants, as they can easily topple over if they get too heavy. A sturdy trellis or cage is a good option. Cucumbers can also be trained to grow up a trellis, which can save space and make harvesting easier.

Another important factor to consider is watering. Both cucumbers and tomatoes need consistent moisture in order to thrive. However, they have different preferences when it comes to soil moisture levels. Cucumbers prefer slightly moist soil, while tomatoes like their soil to be on the drier side. To strike a balance, you may need to water your garden more frequently than you would if you were growing just one of these plants.

Companion Plants for Cucumbers and Tomatoes

While cucumbers and tomatoes are great companions for each other, there are other plants that can also benefit from being grown alongside them. Here are a few examples:

Marigolds

Marigolds are known for their ability to repel pests such as nematodes, which can damage the roots of both cucumbers and tomatoes. They also add a pop of color to your garden!

Basil

Basil is another plant that can help repel pests. It's also a good companion for tomatoes, as it can improve their flavor.

Nasturtiums

Nasturtiums are another colorful addition to your garden, and they can help repel aphids and cucumber beetles.

Harvesting Cucumbers and Tomatoes

When it comes to harvesting your cucumbers and tomatoes, there are a few things to keep in mind. Cucumbers should be picked when they are still small and firm, as they can quickly become bitter if left on the vine too long. Tomatoes, on the other hand, should be allowed to ripen fully on the vine before picking. They will have the best flavor and texture this way.

It's also a good idea to harvest your crops frequently, as this will encourage more growth. If you leave too many cucumbers or tomatoes on the vine for too long, the plant may stop producing new fruit.

FAQs about Cucumbers and Tomatoes Companion Planting

1. Can I grow cucumbers and tomatoes in the same container?

While it is possible to grow both plants in the same container, it's generally not recommended. Cucumbers need a lot of space to spread out, and they can easily overwhelm a tomato plant if they are grown together in a small container.

2. What types of cucumbers and tomatoes are best for companion planting?

There are many different varieties of cucumbers and tomatoes, but some that are particularly well-suited for companion planting include slicing cucumbers and cherry tomatoes.

3. Do I need to fertilize my cucumber and tomato plants?

Yes, both cucumber and tomato plants benefit from regular fertilization. You can use a balanced fertilizer or one that is higher in phosphorus, which can help with fruit development.

4. How often should I water my cucumber and tomato plants?

Both plants need consistent moisture, so you should plan on watering them at least once a week. However, you may need to water more frequently if you live in a hot or dry climate.

5. What pests should I watch out for when growing cucumbers and tomatoes?

Some common pests that can affect both plants include aphids, cucumber beetles, and spider mites. You can use natural pest control methods such as companion planting, row covers, and insecticidal soap to help keep these pests at bay.


Cucumbers and tomatoes are a classic example of companion planting right. By planting these two crops together, you can help them both thrive while also enjoying a bountiful harvest. Just remember to give each plant enough space, provide support for your tomato plants, and water them regularly. With a little bit of care and attention, you'll be well on your way to a successful cucumber and tomato garden.
