10 Great Plants to Grow with Tomatoes for More Tomatoes and Fewer Bugs

Companion planting is a time-honored gardening approach that leverages the natural benefits of certain plant relationships to boost growth and deter pests.

For tomato enthusiasts looking to maximize their harvest and minimize trouble, choosing the right companions can make all the difference.

This guide delves into ten fantastic plants to grow alongside your tomatoes, enhancing their flavor and health while keeping pests at bay.

1. Basil: Boost Flavor and Repel Insects

One of the best companions for tomatoes is basil, not only for its ability to enhance the taste of tomatoes but also for its insect-repelling qualities. Basil emits a strong scent that is unappealing to many garden pests, including thrips and mosquitoes.

By planting basil around your tomatoes, you can create a natural barrier that discourages these pests from feasting on your plants.

Additionally, many gardeners believe that growing basil and tomatoes together helps to improve the flavor of the tomatoes, making this pairing not just practical but also tasty.

2. Marigolds: The Natural Pest Deterrent

Marigolds are not only vibrant and cheerful, but they also play a crucial role in natural pest management.

The roots of marigolds release a substance that is toxic to nematodes—microscopic worms that often cause damage to tomato roots.

Above ground, the strong fragrance of marigolds deters aphids and other pests. Planting marigolds around your tomato garden will add a splash of color while protecting your tomatoes from various harmful pests.

This practice not only enhances the garden’s beauty but also secures the health of your tomato plants.

3. Garlic: A Strong Ally Against Fungal Diseases

Garlic is renowned for its strong aroma, which not only adds zest to dishes but also prevents fungal diseases in the garden.

Planting garlic among tomatoes can help ward off late blight and other common fungal infections that often afflict tomato plants. Garlic acts as a natural fungicide and antibacterial, reducing the need for chemical interventions.

For effective use, intersperse garlic cloves around the tomato plot to ensure that the garlic’s protective properties are well distributed.

4. Borage: The Bee Attractor and Tomato Protector

Borage is an exceptional companion for tomatoes due to its ability to attract pollinators while simultaneously warding off harmful pests such as tomato hornworms.

The star-shaped blue flowers of borage attract bees, essential for the pollination of many garden plants, including tomatoes.

Furthermore, borage is believed to improve tomato growth and flavor. The plant itself is hardy and improves the soil around it by adding trace minerals that are beneficial to tomato health.

Growing borage can therefore bolster your garden’s ecosystem while enhancing the quality and yield of your tomatoes.

5. Carrots: Deep Soil Conditioners

Carrots and tomatoes make excellent neighbors. The fine roots of carrots help to aerate the soil, which promotes better root growth for tomatoes.

This deeper and looser soil allows tomato roots to penetrate more easily, enhancing their access to nutrients and water.

However, timing is crucial when planting carrots with tomatoes; carrots should be sown first to allow them to establish themselves without competing with the tomatoes for space.

Additionally, as the carrots are harvested, they leave behind channels in the soil that further enhance air and water circulation for the tomato plants.

6. Nasturtiums: Colorful Insect Traps

Nasturtiums offer more than just bright splashes of color in your garden. These vigorous plants are known for their ability to attract and trap aphids, which are common pests that can be detrimental to tomatoes.

Nasturtiums act as a decoy, luring aphids away from your tomatoes, effectively reducing damage to your main crop.

Moreover, nasturtium flowers and leaves are edible, adding a peppery zest to salads. Plant nasturtiums around the borders of your tomato beds or in hanging baskets nearby to maximize their pest control benefits while beautifying your garden space.

7. Asparagus: A Long-Term Companion

Pairing asparagus and tomatoes in the garden can be particularly beneficial over the long term. Asparagus plants are perennial, and once established, they can produce for 20 years or more.

Tomatoes, on the other hand, are annuals that can benefit from the asparagus’s ability to repel certain types of nematodes in the soil, which also negatively impact tomato plants.

This symbiotic relationship helps to protect tomatoes each year and improves the overall health of the asparagus. It’s a strategic planting choice for gardeners looking to make the most of their space year after year.

8. Lettuce: Maximizing Garden Space

Lettuce is an excellent companion for tomatoes, particularly in maximizing garden utilization. Tomato plants tend to grow tall and can provide much-needed shade to lettuce, which thrives in cooler temperatures.

This natural umbrella can extend the lettuce growing season, especially in warmer climates. Planting lettuce around the base of tomatoes can also help in keeping the soil moist and weed-free.

This intercropping technique is not only efficient but also makes for a visually appealing garden layout.

9. Chives: Enhance Growth and Flavor

Chives, a mild onion-like herb, are beneficial when planted next to tomatoes. They help prevent bacterial diseases and can improve the taste and health of tomato plants.

Chives also repel pests like aphids and mites, acting as a natural insecticide. Their small purple or white flowers provide an aesthetic boost and can also attract pollinators.

Regularly harvesting chives can stimulate their growth and ensure they continue to benefit your tomatoes throughout the season.

10. Amaranth: The Distractor for Tomato Pests

Amaranth is not just a nutritious grain; its broad leaves also serve as an excellent trap crop for several pests that would otherwise target tomatoes.

Leaf miners, in particular, prefer amaranth over tomato leaves, diverting their attention and minimizing damage to your main crops.

Amaranth can grow quite tall, so it should be planted in a way that does not shade your tomato plants too much.

Besides its role as a protector, amaranth adds a striking visual element to the vegetable garden with its vibrant reds, golds, and greens.

Incorporating these ten plants into your tomato garden can significantly enhance yield, reduce pest issues, and improve overall plant health.

Companion planting is a sustainable step toward a more productive and beautiful garden. Experiment with these companions to see which work best in your climate and soil conditions, and enjoy the process of creating a more interconnected and thriving garden ecosystem.
