Table of Contents

Growing gardens is an exciting experience, and planting cucumbers and tomatoes together is a great way to maximize your garden space. However, not all plants can grow harmoniously, and this is why it's essential to know the dos and don'ts of companion planting. In this article, we'll explore everything you need to know about planting cucumbers and tomatoes together.

Why Plant Cucumbers and Tomatoes Together?

The benefits of growing cucumbers and tomatoes together are numerous, including:

  • Maximizing space in your garden
  • Improving crop yield
  • Reducing pests and diseases

Let's explore how these benefits are achieved:

Maximizing Space in Your Garden

Cucumbers and tomatoes are both vining plants that require a lot of space to spread out. By planting them together, you can train them to grow vertically, which saves space and makes harvesting easier.

Improving Crop Yield

When grown together, cucumbers and tomatoes can benefit each other by sharing nutrients and deterring pests. Tomatoes release solanine, a natural pesticide that repels aphids, while cucumbers produce cucurbitacin, a chemical that deters beetles and other crawling insects.

Reducing Pests and Diseases

Growing different plants together can deter pests and diseases that would otherwise thrive in a monoculture environment. For example, planting marigolds or basil near your tomato and cucumber plants can deter nematodes, while planting garlic or chives can repel aphids.

How to Plant Cucumbers and Tomatoes Together

Here are the steps you need to follow to plant cucumbers and tomatoes together successfully:

Step 1: Choose the Right Varieties

Not all cucumber and tomato varieties grow well together. For example, indeterminate tomatoes that grow tall and require a lot of space may not be suitable for growing with bush cucumbers that spread out on the ground. Choose compact, disease-resistant varieties of both plants that will grow well in your area.

Step 2: Prepare the Soil

Cucumbers and tomatoes prefer well-drained soil rich in organic matter. Prepare the soil by adding compost or aged manure a few weeks before planting. This will ensure that the soil is rich in nutrients and has good drainage.

Step 3: Plant Your Seeds

Plant your seeds according to the instructions on the seed packet. If planting from seedlings, make sure to space them at least two feet apart to give them enough room to grow.

Step 4: Provide Support

As your plants grow, provide support for them to climb. You can use stakes, trellises, or cages for this purpose. Make sure to tie the plants loosely to the support structure to avoid damaging the stems.

Step 5: Water and Fertilize Regularly

Cucumbers and tomatoes need regular watering and fertilization to grow healthy and produce a good crop. Water deeply and regularly, and fertilize with a balanced fertilizer every 2-3 weeks during the growing season.

Harvesting Cucumbers and Tomatoes Together

Cucumbers and tomatoes mature at different rates, but you can still harvest them together. Harvest cucumbers when they reach their full size but are still firm and green. Tomatoes should be left on the vine until they turn red and are fully ripe.

Common Problems When Planting Cucumbers and Tomatoes Together

While planting cucumbers and tomatoes together has many benefits, there are some common problems to watch out for:

Pest Infestations

Cucumbers are susceptible to cucumber beetles, while tomatoes may attract tomato hornworms. Use natural pest control methods like companion planting or organic insecticides to manage infestations.

Fungal Diseases

Both cucumbers and tomatoes are prone to fungal diseases like powdery mildew and blight. To prevent these diseases, avoid watering your plants from above and provide good air circulation around the plants.


Planting cucumbers and tomatoes together is a great way to maximize your garden space and improve your crop yield. By following the steps outlined in this article, you can successfully grow these two plants together and enjoy a bountiful harvest.
