What Should You Not Plant Next to Tomatoes?

Tomatoes are one of the most beloved garden crops, but did you know that some plants can negatively impact their growth and health? To ensure your tomatoes thrive, it’s important to know what not to plant near them. Here are some plants you should avoid planting next to tomatoes:

1. Nightshade plants

Tomatoes belong to the nightshade family, which includes plants like peppers, eggplants, and potatoes. While it’s tempting to group these plants together, it’s not a good idea. Planting nightshade plants next to each other can increase the likelihood of pests and diseases attacking your garden. Avoid planting any member of the nightshade family near your tomatoes to keep them healthy.

2. Brassicas

Brassicas like broccoli, cauliflower, and cabbage can release compounds that inhibit the growth of tomatoes. These plants also attract pests like the cabbage worm and aphids that can damage your tomatoes. Keep these plants away from your tomatoes to avoid stunting their growth and attracting unwanted bugs.

3. Corn

Tomatoes and corn may seem like a natural pairing, but they are not good companions in the garden. Corn attracts the tomato fruitworm, which can devastate your tomato crop. Additionally, the large corn plants can shade and stunt the growth of your tomatoes. If you must plant corn, keep it at least 20 feet away from your tomatoes.

4. Walnuts

Walnut trees release a chemical called juglone that can harm tomatoes and other plants nearby. Juglone is toxic to many plants, including tomato plants. If you have a walnut tree in your yard or a neighbor’s yard, it’s best to keep your tomato plants far away from it.

5. Fennel

Fennel, an herb commonly used in Mediterranean dishes, can affect the flavor of tomatoes. Planting fennel near tomatoes can cause the tomatoes to taste bitter or develop a licorice-like flavor. Keep these two plants away from each other to ensure the best flavor for your tomatoes.

Conclusion

While tomatoes are a popular garden crop, they don’t get along with every plant. By avoiding planting nightshade plants, brassicas, corn, walnuts, and fennel near your tomatoes, you can ensure their growth and health. With a little planning and care, your tomato plants will provide a bountiful harvest throughout the growing season.
