3. Plants to Avoid Near Tomatoes
Brassicas
Brassicas like cabbage, broccoli, cauliflower, kale, and Brussels sprouts compete with tomatoes for nutrients, potentially stunting their growth.
Corn
Corn and tomatoes are both susceptible to the corn earworm and tomato fruitworm. Planting them together increases the risk of these pests spreading.
Potatoes
Potatoes and tomatoes belong to the same plant family and share common pests and diseases like blight. Planting them together can spread these issues.
Fennel
Fennel can inhibit tomato growth by releasing a substance that affects nearby plants. Keep it at a distance from your tomato plants.
Dill
Dill can initially benefit tomatoes, but once it matures, it can hinder their growth. If you must plant dill, keep it away from your tomatoes.
Eggplant
Eggplants, like potatoes, share diseases and pests with tomatoes. This can lead to increased susceptibility to blight and other problems.
Peppers
Peppers and tomatoes are both nightshades, making them susceptible to the same pests and diseases. Keeping them apart can reduce these risks.
Walnuts
Walnut trees produce juglone, a chemical toxic to tomatoes. Avoid planting tomatoes near walnut trees or using their mulch.
Cucumbers
Cucumbers and tomatoes can compete for resources, and cucumbers can spread diseases like cucumber mosaic virus to tomatoes.
Kohlrabi
Kohlrabi competes with tomatoes for nutrients, leading to reduced growth and productivity.
Broccoli
Broccoli and tomatoes compete for the same soil nutrients, making it difficult for both to thrive.
Cauliflower
Like broccoli, cauliflower competes with tomatoes for nutrients and space, hindering their growth.
Cabbage
Cabbage can overshadow tomatoes, reducing sunlight and space availability, which can stunt tomato growth.
Kale
Kale, another brassica, competes with tomatoes for nutrients, affecting their growth and productivity.
Turnips
Turnips can attract pests that also affect tomatoes, increasing the likelihood of infestations.
Beets
Beets and tomatoes can compete for nutrients and space, leading to reduced growth for both plants.
Peas
Peas can inhibit tomato growth through competition for resources and can also attract pests that harm tomatoes.
Garlic
Garlic can stunt tomato growth by competing for nutrients. It’s best to plant garlic away from tomatoes.
