9 Plants To Avoid Planting With Tomatoes This Season
Potatoes
Potatoes and tomatoes belong to the same Solanaceae family and are prone to similar pests and diseases, like late blight, which can spread quickly between the two.
Peppers
Although peppers are also from the Solanaceae family, planting them near tomatoes can increase the risk of disease transmission and pest infestations.
Eggplants
Eggplants are closely related to tomatoes and share similar vulnerabilities to pests and diseases, potentially leading to compounded problems.
Corn
Corn can attract the same pests as tomatoes, such as corn earworms and aphids, which might spread to your tomato plants, affecting their health.
Cabbage
Cabbage and other cruciferous vegetables can compete with tomatoes for nutrients and space, potentially reducing the overall growth and yield of both plants.
Fennel
Fennel exudes a chemical that can inhibit the growth of tomatoes and other plants nearby, making it a poor companion plant.
Dill
Dill can attract pests that also affect tomatoes and may interfere with the growth of your tomato plants due to its allelopathic properties.
Carrots
Carrots and tomatoes have different soil nutrient needs and may compete for resources, which can affect the health and productivity of both crops.
Asparagus
Asparagus can release chemicals into the soil that inhibit tomato plant growth, and their root systems may compete for space and nutrients.
