What Not to Plant with Tomatoes and Peppers

Tomatoes and peppers are popular garden vegetables that produce flavorful and vibrant fruits throughout the growing season. However, some plants should not be planted alongside these nightshade family crops as they can affect their growth, yield, and flavor.

Avoid Planting Brassicas

Brassicas such as broccoli, cauliflower, cabbage, and kale are not compatible with tomatoes and peppers as they release mustard oil compounds that can negatively affect their growth and production. These plants can also attract common pests such as aphids and whiteflies that can infest and weaken the plants, leaving them susceptible to disease and stunted growth.

Don't Plant Fennel or Dill

Fennel and dill are aromatic herbs that can add flavor to many dishes, but they should not be grown alongside tomatoes and peppers as they attract pests such as tomato hornworms, which can damage the plants. These herbs also release chemicals that can stunt the growth and development of the crops.

Avoid Growing Corn and Tomatoes Together

Corn and tomatoes are both heavy feeders that require plenty of nutrients and water to grow well. However, planting them together can lead to competition for resources, resulting in reduced yields or stunted growth. Moreover, corn can attract pests such as corn earworms and aphids that can damage the tomatoes and peppers. If you must plant these crops together, separate them by at least 4 feet, and provide regular fertilization and watering to ensure optimal growth and production.

Don't Plant Potatoes Near Tomatoes and Peppers

Tomatoes and peppers belong to the same family as potatoes and are susceptible to the same soil-borne diseases such as verticillium wilt, bacterial canker, and early blight. Planting potatoes near these crops can transfer these diseases and reduce their growth and yield. Additionally, potatoes may attract pests such as potato beetles and whiteflies that can infest and damage the crops.

Conclusion

By avoiding planting brassicas, fennel, and dill, corn, and potatoes near tomatoes and peppers, gardeners can ensure that these crops grow and produce optimally. By practicing proper crop rotation and companion planting techniques, gardeners can reduce the risk of disease and pest infestations while increasing the yield and quality of their garden vegetables.
