Tomatoes are perfect for summer, but here are some plants they should never be around

1. Potatoes
Potatoes and tomatoes are both members of the nightshade family and are susceptible to common pests and diseases, such as blight. Planting them too closely together can increase the likelihood of these issues, leading to reduced yields and unhealthy plants.
2. Corn
Corn can attract pests like the tomato fruitworm and corn earworm. These pests can easily transfer from corn to your tomato plants, causing significant damage. Keeping these plants apart is vital for preventing infestations.
3. Fennel
Fennel should generally be avoided in vegetable gardens because it tends to inhibit the growth of many surrounding plants, including tomatoes. Its allelopathic properties can stunt the development of nearby crops.
4. Brassicas (Cabbage, Cauliflower, etc.)
Brassicas and tomatoes do not make good garden companions. These veggies can compete for the same nutrients and space, and may hinder each other’s growth when planted closely.
5. Walnut Trees
Juglone, a chemical produced by walnut trees, is toxic to tomatoes. Even proximity to walnut trees can harm your tomato plants, leading to wilting and poor growth.

Gardening can be a complex endeavor, but with the right knowledge, you can create an environment where your plants support each other. Keep these plant pairings in mind, and you’ll be well on your way to a prolific and healthy tomato crop this summer.
