What Not to Plant Near Tomatoes

Tomatoes are a popular crop for home gardeners, providing fresh, juicy fruit for salads and sauces throughout the summer. However, it's important to be mindful of what you plant near your tomato plants, as some plants can have a negative impact on the growth and health of your tomatoes. Here are some plants you should avoid planting near your tomato plants:

1. Members of the Nightshade Family

Tomatoes are part of the nightshade family, which includes other plants such as peppers, eggplants, and potatoes. While these plants are generally compatible with tomatoes, it's important not to plant any other nightshade plants near tomatoes that are infected with pests or diseases. This is because most pests and diseases affecting nightshade plants can also affect tomatoes, and planting them near infected plants can increase the risk of contamination.

2. Brassicas

Brassicas, such as broccoli, cabbage, and cauliflower, can also be harmful to tomatoes. These plants release toxins that can affect the growth and development of tomatoes, and planting them too close to your tomato plants can lead to stunted growth and poor fruit production. If you want to plant brassicas in your garden, make sure to keep them at least 4 feet away from your tomato plants.

3. Fennel

Fennel is a strong-smelling herb that can interfere with the growth of other plants, including tomatoes. Its roots release chemicals that can stunt the growth of tomato plants, and planting fennel near your tomato plants can lead to poor fruit production and stunted growth. Keep fennel at least 4 feet away from your tomato plants to avoid any negative effects.

4. Walnut Trees

Walnut trees can be harmful to many plants, including tomatoes, due to the release of chemicals from their roots called juglones. Juglones can negatively affect the growth and development of tomato plants, leading to stunted growth and poor fruit production. If you have walnut trees in your garden, make sure to keep them at least 50 feet away from your tomato plants to avoid any negative effects.

5. Corn

Corn can be harmful to tomatoes for two reasons. First, corn uses up a lot of nutrients from the soil, which can leave your tomato plants lacking the nutrients they need to grow and produce fruit. Second, corn is prone to attracting insect pests, such as corn borers and earworms, which can also affect your tomato plants. Keep your corn plants at least 4 feet away from your tomato plants to avoid any negative effects.

By being mindful of the plants you plant near your tomato plants, you can ensure that they grow strong and healthy and provide a bountiful harvest throughout the summer. Be sure to keep these plants in mind when planning your garden, and keep them at a safe distance from your beloved tomatoes!
