Introduction

Planting certain types of plants near tomatoes can help improve their growth and reduce the risk of pests and diseases. In this article, we will explore some of the best plants to grow near your tomato plants to help them thrive.

Companion Plants for Tomatoes

One of the best companion plants for tomatoes is basil. Planting basil near your tomatoes can help deter pests such as aphids, spider mites, and hornworms, which can damage your tomato plants. Basil also releases a fragrance that can attract pollinators, such as bees, which are important for the development of your tomato plants.

Another great companion plant for tomatoes is marigold. Marigold has a strong odor that can repel various pests, including nematodes and whiteflies, which can harm your tomato plants. Additionally, marigold can help attract beneficial insects such as ladybugs, which can help keep pest populations under control.

Garlic is another excellent companion plant for tomatoes because it can help repel pests such as spider mites and aphids. Additionally, garlic can help improve the flavor of your tomato plants.

Plants to Avoid Growing Near Tomatoes

While certain plants can be beneficial for your tomato plants, there are some plants that you should avoid growing near them. One of these plants is the potato. Tomatoes and potatoes are both members of the nightshade family and can be susceptible to the same diseases, such as blight. By planting tomatoes and potatoes together, you increase the risk of these diseases spreading between the plants.

Walnut trees and other plants from the Juglandaceae family should also be avoided as they release a chemical compound known as juglone, which is toxic to tomatoes and other nightshade plants. This compound can affect the growth and development of your tomato plants and can even kill them in severe cases.

Conclusion

Planting companion plants near your tomato plants can be a great way to improve their growth and protect them from pests and diseases. Basil, marigold, and garlic are all excellent choices for companion plants that can help improve the quality of your tomato plants. However, it is important to avoid planting certain plants, such as the potato and walnut tree, near your tomato plants to prevent the spread of disease and damage to your plants.
