What Should I Not Plant Next to Tomatoes?

Tomatoes are a popular vegetable that many people enjoy growing in their gardens. However, not all plants are compatible with tomatoes. Some plants can attract pests or diseases that can harm tomatoes, while others may compete for nutrients and water. In this article, we will explore what plants you should not plant next to tomatoes and why.

Plants to Avoid Planting Next to Tomatoes

1. Potatoes: Potatoes and tomatoes are both members of the nightshade family. If you plant these two crops next to each other, they can attract common pests such as Colorado potato beetles, which can destroy both crops.

2. Fennel: Fennel can release chemicals that inhibit the growth of other plants. If you plant tomatoes next to fennel, the tomatoes may not grow as tall or produce as much fruit.

3. Brassicas: This family includes vegetables such as broccoli, cauliflower, and cabbage. These plants require a lot of nutrients and can compete with tomatoes for water and soil nutrients. Additionally, if planted next to tomatoes, brassicas can attract pests such as aphids and flea beetles.

4. Corn: Corn and tomatoes both require a lot of nutrients from the soil. If planted next to each other, they can compete for these nutrients, which can result in stunted growth and smaller yields for both crops.

Plants That Can Benefit Tomatoes

1. Basil: Basil is an herb that can improve the flavor of tomatoes and repel pests such as flies and mosquitoes. Planting basil next to tomatoes can also increase the yield and growth of the tomatoes.

2. Marigolds: Marigolds are known for their ability to repel pests and attract beneficial insects such as ladybugs and bees. Planting marigolds next to tomatoes can help protect them from pests and increase pollination.

3. Nasturtiums: Like marigolds, nasturtiums can also attract beneficial insects to your garden, such as bees and butterflies. They can also repel pests such as aphids.

Conclusion

When planning your garden, it's important to consider what plants are compatible with each other. While tomatoes are a popular choice, they may not grow as well if planted next to certain plants. Avoid planting potatoes, fennel, brassicas, and corn next to tomatoes. Instead, plant basil, marigolds, or nasturtiums, which can benefit and protect your tomatoes from pests and improve their growth and yield.
