Best Tomato Companion Plants in My Garden (A Few Break the “Rules” but Here’s How I Make Them Work)

You just planted your tomato plants, and now you may be wondering what companion plants go well with tomatoes. Today, I’m going to share with you companion plants that you can plant with your tomatoes. Some of them may not be found on the ideal companions charts, but I’ll show you some tricks so that you can make them work.

One of the companions I want to show you in my garden is squash. I grow squash with tomatoes in my straw bales, and it works perfectly because the squash plant is situated a little bit in front of the tomato plants, allowing them to be put against a trellis. Another great companion plant is cantaloupe, which climbs up the trellis beside the tomatoes. By tucking cantaloupe in between my tomato plants, I can get even more harvest of my favorite melons. Additionally, I love planting beans, carrots, flowers like calendula and alyssum, onions, basil, cover crops like hairy vetch, cilantro, and peppers as companion plants with tomatoes. These companion plants attract beneficial insects, provide shade, enrich the soil, maximize space, and promote pollination. Just remember to consider sunlight requirements and proper spacing when planting companion plants with tomatoes.

Companion Plants for Tomatoes

Squash

Planting squash near your tomatoes can provide a number of benefits. Squash plants have large, sprawling leaves that can shade the soil around the base of the tomato plants, helping to retain moisture and keep the soil temperature cooler. Additionally, the prickly leaves of squash can act as a natural deterrent to pests such as aphids and spider mites, which are common tomato pests.

Cantaloupe

Cantaloupe is another great companion plant for tomatoes. Like squash, cantaloupe plants have large leaves that can provide shade to the tomato plants. Additionally, the flowers of cantaloupe attract important pollinators like bees and butterflies, which can help improve fruit set and overall yield.

Bush Beans

Bush beans are a fantastic companion plant for tomatoes because they help to improve the soil in which the tomatoes are growing. Beans are nitrogen-fixing plants, which means they draw nitrogen from the air and fix it into the soil. This can help provide an added boost of nitrogen to the tomatoes, which is essential for healthy growth and fruit development.

Carrots

Planting carrots alongside your tomatoes can be beneficial for a couple of reasons. First, carrot roots grow deeper into the soil, which can help break up compacted soil and improve drainage for the tomatoes. Additionally, the strong scent of carrots may help to deter pests such as the carrot fly, which can damage tomatoes.

Flowers

Planting flowers in close proximity to your tomatoes can have several benefits. Some flowers, such as marigolds and nasturtiums, are believed to repel pests like aphids and whiteflies. Others, such as borage and zinnias, attract pollinators and beneficial insects that can help control pests and promote overall plant health.

Onions

Onions are a natural deterrent to many common tomato pests, including aphids and thrips. Planting onions near your tomatoes can help deter these pests and reduce the risk of infestation. Additionally, onions can help improve the flavor of tomatoes when planted together due to their complementary flavors.

Basil

Basil is not only a delicious herb to have in your garden, but it also makes a great companion plant for tomatoes. Basil can help repel pests such as aphids and whiteflies, as well as attract beneficial insects like bees and butterflies. Additionally, the strong aroma of basil can help mask the scent of tomatoes, making them less attractive to pests.

Cover Crops

Cover crops play an important role in companion planting for tomatoes. Cover crops, such as clover or vetch, can be planted between rows of tomatoes to help suppress weeds, improve soil structure, and provide additional nutrients to the soil as they decompose. This can lead to healthier and more productive tomato plants.

Cilantro

Cilantro is a popular herb that can be grown alongside tomatoes as a companion plant. Cilantro attracts beneficial insects like hoverflies and parasitic wasps, which can help control pests such as aphids and caterpillars. Additionally, the strong scent of cilantro may help mask the scent of tomatoes, reducing the risk of pest infestation.

Peppers

Peppers and tomatoes are natural companions in the garden. They have similar growing requirements and can benefit from being planted together. Peppers can help repel pests such as aphids and spider mites, which are common tomato pests. Additionally, planting peppers near tomatoes can provide some shade to the tomato plants, helping to keep the soil temperature cooler.

Breaking the Traditional Rules

When it comes to companion planting for tomatoes, it’s important to remember that these guidelines are not set in stone. While there are certain plants that are commonly recommended as companions for tomatoes, it’s always a good idea to experiment and see what works best in your own garden. Don’t be afraid to break the traditional rules and try out new combinations of plants.

How to Make Them Work

To make companion planting work effectively, consider the following tips:

  1. Plan your garden layout carefully to ensure that your companion plants are placed in the appropriate locations to maximize their benefits.
  2. Pay attention to the sunlight requirements of each plant. Some companion plants may prefer full sun, while others thrive in partial shade. Be sure to match the sunlight needs of your companion plants with the available conditions in your garden.
  3. Proper spacing is essential. Be mindful of the recommended spacing requirements for each plant to ensure they have enough room to grow and access to adequate sunlight and nutrients.
  4. Rotate your companion plants each season to prevent the buildup of pests and diseases in the soil. This can help maintain the health and productivity of your tomato plants year after year.

Benefits of Companion Planting

Companion planting offers a range of benefits for your tomato plants and your garden as a whole. Let’s explore some of the advantages of companion planting for tomatoes.

Attracting Beneficial Insects

Many companion plants, including flowers like marigolds and herbs like basil and cilantro, attract beneficial insects to the garden. These insects, such as bees, butterflies, ladybugs, and parasitic wasps, can help control pest populations and promote pollination. By attracting these beneficial insects, companion plants can contribute to the overall health and productivity of your tomato plants.

Providing Shade

Certain companion plants, such as squash, cantaloupe, and peppers, have large leaves that can provide shade to the base of the tomato plants. This shade can help regulate soil temperature, prevent moisture loss, and reduce weed growth. Additionally, providing shade to the tomato plants can help protect them from sunburn during hot summer months.

Enriching the Soil

Some companion plants, like bush beans and cover crops, can help enrich the soil in which your tomatoes are growing. Beans are nitrogen-fixing plants, which means they convert nitrogen from the air into a form that can be used by other plants. This nitrogen enrichment can help provide essential nutrients to the tomato plants, leading to healthier growth and higher yields. Cover crops, on the other hand, can help improve soil structure, suppress weeds, and add organic matter as they decompose.

Maximizing Space

Companion planting allows you to maximize the use of limited garden space. By interplanting, you can grow multiple crops together and take advantage of shared resources, such as sunlight, water, and nutrients. This can be especially helpful in small gardens or raised beds where space is at a premium. By carefully selecting companion plants, you can optimize the use of space and increase overall garden productivity.

Promoting Pollination

Companion plants, particularly those with attractive flowers, can help promote pollination in your garden. Pollinators like bees and butterflies are attracted to the flowers of companion plants and will visit them while foraging for nectar and pollen. These pollinators can then transfer pollen from the companion plants to the flowers of your tomato plants, leading to improved fruit set and higher yields.

Considerations for Companion Planting

While companion planting can be highly beneficial, it’s important to consider certain factors to ensure success.

Sunlight Requirements

One of the most important factors to consider when companion planting is the sunlight requirements of each plant. While some companion plants prefer full sun, others thrive in partial shade. It’s crucial to match the sunlight needs of your companion plants with the available conditions in your garden. This will help ensure that each plant receives the appropriate sunlight exposure for healthy growth and development.

Proper Spacing

Proper spacing is essential for companion planting. Each plant, including tomatoes and their companion plants, has specific spacing requirements to allow for optimal growth and access to sunlight, water, and nutrients. Be sure to consult planting guides or seed packets for recommended spacing distances. Overcrowding can lead to competition for resources, increased risk of disease, and reduced productivity.
