Introduction

Tomatoes are a popular, nutritious fruit that many gardeners love to grow. They can be grown in pots or in the ground, and in a variety of climates. However, not all plants are suitable to be grown around tomatoes. In this article, we will discuss what plants should not be planted near tomatoes, and why.

What Not to Plant Near Tomatoes: Nightshade Family

The first group of plants to avoid planting near tomatoes is the nightshade family. This includes other popular garden vegetables such as peppers, eggplant, and potatoes. The reason for this is that members of the nightshade family all belong to the same plant family, Solanaceae, which means they are all susceptible to similar diseases and pests. By planting them too close together, it increases the chances of diseases and pests becoming more destructive. Additionally, the nightshade family plants all need similar nutrients from the soil, which means they can compete with each other for those nutrients, leading to fewer and less healthy plants. Tomatoes and other nightshade family plants should be at least four feet apart from each other.

What Not to Plant Near Tomatoes: Brassica Family

Another family of plants to avoid planting near tomatoes is the brassica family. This includes vegetables like broccoli, cabbage, and cauliflower. The reason for this is that brassica family plants can attract certain pests that can also damage tomato plants. Additionally, brassica family plants need a lot of nitrogen from the soil, which means they can compete with tomatoes for that nutrient. Tomatoes and brassica family plants should be at least two feet apart from each other.

What Not to Plant Near Tomatoes: Fennel

Fennel is an herb that should also be avoided when planting near tomatoes. The reason for this is that fennel can attract a specific pest called the tomato hornworm. This pest can cause damage to tomato plants and lead to a decreased harvest. Additionally, the roots of fennel release certain chemicals that can inhibit tomato growth. Tomatoes and fennel should be at least ten feet apart from each other.

What to Plant Near Tomatoes

Now that we've covered what not to plant near tomatoes, let's discuss what plants are compatible with tomatoes. One great plant to grow near tomatoes is basil. Basil can actually help repel certain pests that can damage tomato plants. Additionally, basil and tomatoes have similar growing conditions and nutrient needs, which means they can complement each other and lead to a healthier garden. Other compatible plants include marigolds, which can also repel pests, and beans, which can add nitrogen to the soil.

Conclusion

In conclusion, when planting tomatoes, it's important to be mindful of what plants to avoid planting near them. Members of the nightshade family, brassica family, and fennel should all be planted at a distance from tomatoes to avoid increased disease and pest presence, as well as nutrient competition. On the other hand, basil, marigolds, and beans are all great options to be grown near tomatoes. Happy gardening!
