What should not be planted next to tomatoes?

When it comes to planting tomatoes, there are a few plants that you should avoid planting next to them. These plants can have negative effects on the growth and health of tomato plants. Let’s take a look at some plants that should not be planted next to tomatoes and the reasons behind it.

1. Aromatic Herbs: Aromatic herbs like sage and rosemary are commonly used in cooking and have wonderful flavors. However, when it comes to planting them next to tomatoes, it’s best to avoid it. These herbs contain natural oils that can inhibit the growth of tomatoes. The oils can slow down the growth of tomato plants and affect their overall health. It’s best to keep these herbs in a separate area away from your tomato plants to ensure their optimal growth.

2. Brassicas: Plants like broccoli, cabbage, and cauliflower are part of the brassica family. While these vegetables are nutritious and delicious, they can compete with tomatoes for the same nutrients in the soil. Planting brassicas next to tomatoes can result in nutrient deficiency for both plants. The competition for nutrients could lead to stunted growth and reduced yields for both crops. It’s best to keep a distance between tomatoes and brassicas to ensure that they both thrive in their own space.

3. Potatoes: Potatoes are another plant that should not be planted next to tomatoes. Both tomatoes and potatoes are susceptible to similar diseases and pests, such as blight and aphids. By planting them next to each other, you increase the risk of diseases spreading between the two crops. Additionally, potatoes have a tendency to shade out other plants, including tomatoes, which require full sun for optimal growth. It’s best to give each crop its own designated space to avoid any negative impacts.

4. Corn: Corn is a tall and dense plant that can cast shade on neighboring plants, including tomatoes. Tomatoes require a good amount of sunlight to thrive and produce abundant fruit. Planting corn too close to tomatoes can result in reduced sunlight exposure for the tomato plants, leading to decreased yields. It’s best to provide enough distance between corn and tomatoes to ensure that both crops receive the necessary sunlight.

5. Fennel: Fennel is a herb with a distinctive licorice flavor that can be overpowering for some dishes. While it has its culinary uses, fennel should not be planted next to tomatoes. Fennel is known to release certain chemicals into the soil that can inhibit the growth of tomato plants. It’s best to keep fennel in a separate area of the garden to avoid any negative effects on your tomato plants.

When planting tomatoes, it’s important to be mindful of the plants that should not be planted next to them. Aromatic herbs like sage and rosemary, brassicas like broccoli and cabbage, potatoes, corn, and fennel can all have negative impacts on the growth and health of tomato plants. By giving each crop its own designated space, you can ensure that they all thrive and produce abundant yields. Happy gardening!
