What shouldn't you plant with tomatoes

Tomatoes are one of the most popular vegetables to grow in home gardens. They are relatively easy to cultivate, and they thrive in warm weather. However, not all plants are compatible with tomatoes. Some plants can harm the growth of tomatoes or attract pests. In this article, we will look at what plants you should avoid planting with tomatoes.

Avoid planting nightshade vegetables with tomatoes

One of the most obvious plants to avoid planting with tomatoes is other nightshade vegetables. Nightshade vegetables, such as peppers, potatoes, and eggplants, are all from the Solanaceae family. While they may look beautiful next to your tomatoes, planting them together can lead to problems. All Solanaceae plants are susceptible to the same diseases and pests. If any of them get infected, the disease can quickly spread to the other plants in the same family. Rotating crops annually can help, but it is still best to keep those plants apart.

Don’t plant brassicas or fennel with tomatoes

Brassicas, such as broccoli, kale, and cauliflower, and fennel are two other plants that should be avoided planting with tomatoes. Brassicas and fennel have a chemical compound that can inhibit the growth of tomatoes. It's said that if you plant brassicas near tomatoes, it can lead to stunted growth, and the tomatoes may take longer to ripen. Additionally, planting fennel near tomatoes can cause their fruit to take on a strange flavor. So it is best to avoid planting these plants together.

Avoid planting corn with tomatoes

Another plant that shouldn't be planted near tomatoes is corn. It is said that corn and tomatoes both take a lot of nitrogen from the soil, which can cause the plants to fight for nutrients. This can result in stunted growth for both plants. Additionally, planting corn near tomatoes can attract pests that also harm tomatoes, such as the tomato fruit worm. It is best to keep those plants apart.

Conclusion

While there are many plants that work well alongside tomatoes, some should be avoided. Plants from the same family, like nightshade vegetables, can lead to the spread of pests and diseases. Brassicas and fennel can inhibit tomato growth, and planting corn can lead to competition for nutrients and attract pests. By avoiding these plants, you can help ensure healthy growth and harvest of your tomatoes.
