Hello! As a horticulturist with years of experience in plant cultivation, I can provide you with some insights on which plants should not be planted with tomatoes.

Tomatoes are quite sensitive to certain plants due to their specific nutrient needs, susceptibility to diseases, and the potential for competition for resources. Here are a few plants that are generally not recommended to be planted with tomatoes:


1. Potatoes - Both are susceptible to the same diseases, which can easily spread from one to the other.

2. Brassicas (like cabbage, cauliflower, and broccoli) - These plants can attract pests that also affect tomatoes.

3. Fennel - It can inhibit tomato growth and may also attract pests.

4. Kohlrabi - Similar to brassicas, it can attract pests that are harmful to tomatoes.

5. Solanaceae Family (like peppers, eggplants, and tomatillos) - While they are closely related, they can also share diseases and pests.

6. Corn - It can overshadow tomatoes, blocking sunlight and reducing air circulation, which can lead to disease.
7.
Dill - Some gardeners believe that dill can attract pests that are harmful to tomatoes.

It's important to note that while these plants are generally not recommended for planting with tomatoes, there are exceptions based on specific growing conditions and practices. Always consider your local climate, soil conditions, and the specific varieties of plants you are growing.
