Tomatoes and pepper plants have similar sizes but tomatoes grow on vines while pepper plants are sturdy enough to stand on their own. While the pepper plant provides a natural climbing structure for tomatoes, tomatoes emit a natural chemical called solanine, which acts as a natural insect repellent.

Another benefit of companion planting tomatoes with pepper plants is improved pollination. Both tomato and pepper plants require pollination to produce fruits, and having a variety of flowers nearby increases the chances of attracting pollinators like bees and butterflies. This ultimately leads to higher yields and better fruit sets for both plants.

3. Garlic
