Can You Plant Tomatoes Alongside Brussels Sprouts?

Many gardeners wonder if it is possible to plant tomatoes alongside Brussels sprouts. While there are conflicting opinions on this matter, it is important to consider various factors before deciding whether to grow these two plants together. In this article, we will explore the benefits and drawbacks of companion planting tomatoes and Brussels sprouts, as well as tips for successful cultivation.

The Conflicting Views

When researching this topic, it becomes apparent that there are differing opinions on whether tomatoes and Brussels sprouts can be planted together. Some sources suggest that these plants are suitable companions and can be grown side by side. They argue that planting them together can save space in the garden, as both plants can share the same growing season. Additionally, the Brussels sprouts can provide support for the tomato plants and protect them from excessive sunlight and moisture.

On the other hand, opposing views suggest that tomatoes and Brussels sprouts are not recommended to be planted together. These sources argue that they are “enemies” in the garden and may rob each other of nutrients if planted too closely. Tomatoes and Brussels sprouts have different growing needs and mature at different rates, which can lead to competition for resources. Furthermore, as Brussels sprouts belong to the Cole Crop (Brassica) family, they can stunt the growth of tomato plants.

The Importance of Research

Considering the conflicting views, it is crucial for gardeners to conduct their own research and take into account their specific gardening conditions. Factors such as soil quality, sunlight exposure, and available space should all be considered when deciding whether to plant tomatoes and Brussels sprouts together.

Tips for Successful Cultivation

If you decide to plant tomatoes alongside Brussels sprouts, here are some tips to increase your chances of success:

  1. Provide Ample Space: It is recommended to give both plants enough room to grow. Plant tomatoes in full sun and provide at least two feet of space between each plant. Brussels sprouts, on the other hand, prefer partial shade and should be spaced three to four feet apart.
  2. Consider Timing: To avoid competition between the two plants, consider planting tomatoes as annuals and Brussels sprouts as biennials. This way, you can harvest the tomatoes before the Brussels sprouts take over the space.
  3. Companion Planting: Companion planting with marigold flowers, catnip, and rue can help repel pests and keep Brussels sprout pests at bay. Other compatible plants to grow with Brussels sprouts include potatoes, onions, carrots, and cabbage.
  4. Water and Soil: Both tomatoes and Brussels sprouts require sufficient water and well-drained soil. Regular watering and proper soil preparation are essential for their healthy growth.
  5. Harvesting: Harvest Brussels sprouts when they reach the size of a tennis ball for the best flavor and texture.
  6. Avoid Brassicas Near Tomatoes: It is advisable to avoid planting cabbage or other brassicas near tomatoes, as they can inhibit the growth of tomato plants.

By following these tips, you can increase your chances of successfully growing tomatoes and Brussels sprouts in the same garden.


In conclusion, the question of whether you can plant tomatoes alongside Brussels sprouts does not have a definitive answer. While some sources suggest they can be grown together, others caution against it. It is essential to consider your specific gardening conditions, conduct research, and experiment to determine what works best for your garden.

Remember, gardening is a continuous learning process, and what works for one gardener may not work for another. So, don’t be afraid to try new things and adapt your gardening techniques based on your observations and experiences.
