Why Some Plants Should Not Be Planted with Tomatoes

Tomatoes are a popular choice for many home gardeners because they are relatively easy to grow and produce an abundance of fruit. However, not all plants thrive when grown next to tomatoes. Here are some plants that should not be planted with tomatoes.

Potatoes

Tomatoes and potatoes are both members of the nightshade family, so they are prone to the same pests and diseases. Planting them together can lead to a buildup of harmful pathogens in the soil, which can affect the yield and quality of both crops. In addition, potatoes are much more susceptible to blight than tomatoes, which can quickly spread and destroy the entire crop if left unchecked.

Fennel

Fennel has a reputation for being a great companion plant because it attracts pollinators and repels harmful pests. However, it is not a good match for tomatoes because it can inhibit their growth and development. This is because fennel produces a natural chemical called anethole, which can stunt the growth of other plants around it. If you want to grow fennel in your garden, it's best to plant it in a separate location away from your tomatoes.

Brassicas

Brassicas, such as broccoli, cauliflower, and cabbage, are known for their nutrient-rich properties and are often grown in vegetable gardens. However, they are not compatible with tomatoes because they both have high nutrient requirements. When grown together in the same soil, they will compete for the same nutrients, which can lead to poor growth and yield for both crops. It's best to rotate these crops every season or plant them in different areas of your garden.

Corn

Corn and tomatoes may look good next to each other in the garden, but they don't make good companions. This is because they both have high nutrient requirements, and planting them together can lead to an imbalance in the soil. In addition, corn has a tendency to attract pests like earworms, which can also affect the quality of your tomatoes.

In Conclusion

While it may be tempting to plant all of your favorite vegetables together in the same garden, it's important to choose your companion plants carefully. Some plants, like the ones mentioned above, can have a negative impact on your tomatoes if they are planted too close together. By choosing the right companions for your tomatoes, you can help ensure a healthy, productive garden.
