Companion planting can help your tomatoes by improving soil conditions, deterring tomato pests, and enhancing the overall ecosystem around your tomato plants. It's about creating a harmonious environment where different plants support each other, leading to a thriving garden.
The Best Companion Plants for Tomatoes
Identifying the best companion plants for tomatoes is crucial for maximizing the health and yield of your tomato rows. By strategically planting these beneficial plants alongside your tomatoes, you create a symbiotic relationship where tomatoes can help and be helped, fostering a robust and productive garden ecosystem. Below are the best ones you should try:
Basil
Beyond flavor enhancement, basil's aromatic oils can bolster tomato plant health by repelling common pests like flies and mosquitoes, promoting overall plant vigor.
Tips:
- Intercrop basil between tomato plants to enhance their growth and protect them from pests.
- Use basil clippings as mulch around tomatoes to release aromatic oils that benefit tomato health.
- Regularly harvest basil to encourage a bushier growth that benefits neighboring tomatoes.
- Pair basil with tomatoes in your watering schedule; both prefer similar moisture levels.
- Plant basil on the south side of tomatoes to avoid shading while maximizing sun exposure.
Marigold
French marigolds are particularly effective in deterring nematodes, safeguarding tomato roots from potential damage, and ensuring a healthier root system throughout the growing season.
Tips:
- Plant a border of French marigolds around your tomato bed to create a nematode barrier.
- Integrate marigold cuttings into the soil at the end of the season to further deter nematodes.

Tips:
- Plant nasturtiums in hanging baskets to optimize space and pest control.
- Regularly check the underside of nasturtium leaves for pests and remove them manually.
- Allow nasturtiums to spread naturally to create an effective pest barrier.
- Use nasturtium flowers to add color and attract beneficial insects to the garden.
- Combine nasturtium plantings with marigolds to create a diversified pest deterrent strategy.
Chives
Chives: Regular harvesting of chives stimulates the release of their pest-repellent properties, offering ongoing protection against common tomato pests while enhancing flavor.
Tips:
- Plant chives in clusters for a stronger pest-repelling effect.
- Trim chives regularly to encourage bushy growth and continuous pest repellence.
- Chives can improve soil quality; incorporate their trimmings into compost for tomatoes.
- Use chives' flowers to attract pollinators, enhancing the garden's biodiversity.
- Integrate chives with other alliums like garlic and onions to strengthen the pest deterrent barrier.
Beans
Beans: Nitrogen fixation by beans enriches the soil, providing a nutrient boost for tomatoes without competing for resources, fostering a mutually beneficial relationship.
Tips:
- Rotate bean plantings yearly around tomatoes to enrich different soil areas.
- Utilize bean plant residue as green manure to improve soil fertility for tomatoes.
- Plant beans a few weeks before tomatoes to establish them without overshadowing.
- Monitor for bean pests that might also affect tomatoes, employing integrated pest management practices.
- Use low-growing bean varieties to avoid shading and ensure mutual benefits.
Cucumbers
Cucumbers: Sharing similar requirements without competing for nutrients, cucumbers coexist harmoniously with tomatoes, maximizing garden space and overall productivity.
Tips:
- Train cucumbers on trellises parallel to tomato supports to optimize space and sun exposure.
- Plant cucumbers downwind from tomatoes to prevent disease spread.
- Maintain a watering schedule that suits both cucumbers and tomatoes, considering their similar water needs.

Plants to Avoid Near Tomatoes
While companion planting with tomatoes can significantly benefit your garden, it's crucial to know which plants to avoid to ensure the health and productivity of your tomato patch. Certain plants, when planted near your tomato plants, can hinder growth, attract pests, or cause other adverse effects. Understanding which plants grow well with tomatoes and which should be kept away is key to fostering a thriving garden. This section will guide you on what not to plant near your tomatoes, ensuring your tomato transplants, basil plants, and other garden plants thrive without the interference of incompatible neighbors.
Fennel
Fennel emits substances that can inhibit the growth and development of nearby plants, including tomatoes. Planting fennel near tomatoes may hinder their growth and overall productivity.
Cabbage Family (Brassicas)
Plants like cabbage, broccoli, and cauliflower from the Brassica family can attract similar pests and diseases as tomatoes, increasing the risk of infestations and infections for both crops when planted in close proximity.
Corn
Corn plants are heavy feeders and can compete with tomatoes for nutrients and water, potentially stunting the growth of tomato plants and reducing their yield.
Potatoes
Both tomatoes and potatoes are susceptible to similar diseases, such as blight. Planting them near each other increases the risk of disease transmission and can lead to widespread infection in both crops.
Walnuts (and Black Walnuts)
Walnut trees, including black walnuts, release juglone, a chemical compound toxic to many plants, including tomatoes. Planting tomatoes near walnut trees can lead to poor growth, yellowing leaves, and overall reduced vigor due to juglone toxicity.
