Plants To NEVER Grow Near Your Tomatoes

There are certain plants that are not recommended to grow near tomatoes due to various reasons, such as competition for nutrients, potential disease transmission, or pest attraction. Here are some plants you should avoid planting near your tomatoes:

Potatoes (Solanum tuberosum): Both tomatoes and potatoes belong to the Solanaceae family and are susceptible to similar diseases, such as blight. Planting them together can increase the risk of spreading diseases between the two.

Fennel (Foeniculum vulgare): Fennel can inhibit the growth of tomatoes and other plants due to its allelopathic properties. It releases chemicals into the soil that can hinder the growth of nearby plants.

Cabbage Family (Brassica spp.): Plants in the cabbage family, including cabbage, broccoli, cauliflower, and Brussels sprouts, can stunt the growth of tomatoes and vice versa.

Corn (Zea mays): Corn is a heavy feeder that competes for nutrients with tomatoes. Additionally, tall corn plants can shade tomatoes, affecting their growth.


Dill (Anethum graveolens): Dill can attract tomato hornworms, which are common pests that can damage tomato plants.

Walnuts (Juglans spp.): Walnut trees release a substance called juglone, which is toxic to many plants, including tomatoes.

Amaranth (Amaranthus spp.): Amaranth can compete with tomatoes for nutrients and may hinder their growth.

Kohlrabi (Brassica oleracea var. gongylodes): Kohlrabi is from the same family as cabbage and can have similar effects on tomatoes.
