What Not to Plant Near Tomatoes

Tomatoes are a favorite among gardeners, but they require specific conditions to thrive. While some plants may complement tomatoes in a garden, others can have adverse effects on their growth. In this article, we will discuss what not to plant near tomatoes and why.

Don't Plant Nightshade Family Members Near Tomatoes

The nightshade family includes plants such as peppers, eggplants, and potatoes. They all contain a toxic alkaloid called solanine, which can lead to stunted growth and diseases in tomatoes. When planting tomatoes, it is best to avoid planting them near any nightshade family members.

Don't Plant Brassicas Near Tomatoes

The brassica family includes plants such as broccoli, cauliflower, and cabbage. These plants host several pest species, including the cabbage worm, which can damage tomatoes. Additionally, brassicas require a high level of nutrients from the soil, depleting the resources tomatoes need to grow. Avoid planting brassicas near tomatoes to ensure healthy growth.

Don't Plant Walnut Trees Near Tomatoes

Walnut trees secrete a chemical called juglone, which can be toxic to tomatoes. Juglone can cause wilting, stunting, and even death in plants. The chemical can spread through the soil and reach the roots of nearby plants, including tomatoes. It is best to avoid planting walnut trees near any plants you wish to grow, including tomatoes.

Don't Plant Fennel Near Tomatoes

Fennel is an herb that releases chemical compounds as it grows. These chemicals can inhibit the growth of tomatoes, leading to stunted growth and reduced yields. Additionally, fennel attracts pests such as aphids, which can damage tomato plants. It is best to avoid planting fennel near tomatoes or any other plants you wish to grow.

Don't Plant Corn Near Tomatoes

Corn is another plant that requires abundant resources from the soil, depleting the nutrients tomatoes need to grow. Additionally, it attracts pests such as the tomato fruitworm and corn earworm, which can damage tomato plants. Avoid planting corn near tomatoes to ensure healthy growth.

Conclusion

To grow healthy tomatoes, it is essential to consider what not to plant near them. Plants such as those in the nightshade and brassica families can harm tomatoes, while walnut trees, fennel and corn can deplete the soil's nutrients and attract pests. By avoiding planting these plants near tomatoes, you can ensure healthy growth and high yields.
