What Not to Plant with Tomatoes

Tomatoes are a popular garden plant that require unique care and attention. While they can be grown alongside a variety of other plants, there are specific crops that should not be planted near tomatoes. Here are some plants that should be avoided when deciding what to plant with tomatoes.

1. Brassicas

Brassicas, such as broccoli, cauliflower, and Brussels sprouts, should not be planted with tomatoes. These plants require similar nutrients to tomatoes, making competition for these resources fierce. Additionally, both brassicas and tomatoes are susceptible to the same diseases such as verticillium wilt and clubroot. Planting them too close together increases the likelihood of these diseases spreading and destroying both crops.

2. Nightshade Plants

Tomatoes belong to the nightshade family, which includes plants such as peppers, potatoes, and eggplants. However, planting nightshade plants too close together can lead to insect infestations and the spread of diseases. This is especially true for peppers and tomatoes as they are both highly susceptible to bacterial spot, which can quickly devastate entire crops. Allow a good distance, around three to four feet, between tomatoes and other nightshade plants to avoid these types of problems.

3. Corn

Corn is another plant that should not be planted with tomatoes. These crops take up a lot of space and energy, so if they are planted too close together, they will compete for resources, reducing the overall yield of both plants. Additionally, corn can be a host to pests, such as corn earworms or stalk borers, which can quickly spread to other plants in the vegetable garden, including tomatoes.

4. Kohlrabi

Kohlrabi is another plant that can negatively impact tomato growth. Similar to brassicas, kohlrabi requires a lot of the same nutrients as tomatoes. This can result in a competition for resources that ultimately results in stunted growth for both plants. Additionally, kohlrabi is a host to a variety of pests, such as aphids and cabbage worms, which can quickly spread to other plants, including tomatoes.

5. Fennel

Fennel is an herb that has a potent scent, which can harm the flavor of tomatoes. When planted too close together, the tomato plants can take on the flavor of the fennel, ruining their taste. If you are determined to plant fennel, it is recommended that you keep it at least 10 feet away from your tomato plants.

Conclusion

To ensure a successful tomato crop each year, it is important to carefully plan what to plant with them. Avoiding brassicas, nightshade plants, corn, kohlrabi, and fennel when planting tomatoes will help ensure healthy growth and yields. By following these tips, you'll be able to grow a bountiful tomato harvest that tastes great all season long!
