Did You Know?
1. Did you know that planting onions with tomatoes can actually repel pests? Onions emit a strong odor that deters pests like aphids and spider mites, helping to protect your tomato plants.
2. Believe it or not, planting onions alongside tomatoes can enhance their flavor! The sulfurous compounds released by onions can actually intensify the taste of tomatoes, making them even more delicious.
3. If you’re looking to boost your tomato plant’s growth, planting onions nearby can do the trick. Onions release ethylene gas, which stimulates fruit ripening and can lead to larger, more abundant tomatoes.
4. Onions and tomatoes also make great companions in terms of nutrient absorption. While tomatoes are known for their high potassium requirements, onions are great accumulators of this mineral. Planting them together allows the tomatoes to indirectly benefit from the onion’s potassium-rich soil environment.
5. As an added bonus, planting onions with tomatoes can even help with weed control! Onions produce dense foliage that shades the ground, impeding weed growth and reducing competition for nutrients and water between your desired plants and pesky weeds.
Marigolds: Beneficial Plants For Tomatoes
When it comes to companion planting, marigolds are often lauded for their ability to repel harmful insects and nematodes. But did you know that these vibrant flowers can also be beneficial to tomato plants? Planting marigolds alongside your tomatoes can help enhance their growth and provide a natural deterrent against pests.
Marigolds release a strong aroma that pests, such as aphids and whiteflies, find unappealing. This makes them an excellent companion plant for tomatoes, as they can help prevent infestations and reduce the need for chemical pesticides. Additionally, marigolds attract beneficial insects, like ladybugs and hoverflies, which devour pests that may attack your tomatoes.
When planting marigolds with tomatoes, ensure that the marigold flowers are grown nearby rather than directly next to the tomato plants. This allows their beneficial properties to reach the surrounding area and provides space for air circulation between the two plants, which can help prevent diseases.
Garlic: Companion Planting With Tomatoes
Garlic is not only a delicious culinary herb, but it also possesses natural pest-repellent properties, making it an excellent companion plant for tomatoes. When grown alongside tomatoes, garlic can help deter pests that commonly affect tomato plants, such as aphids, spider mites, and whiteflies.
The strong-smelling compounds emitted by garlic help mask the scent of tomato plants, making it harder for pests to locate them. This can significantly reduce the risk of infestation and protect your tomatoes from damage caused by these insects. Furthermore, garlic has natural anti-fungal properties, which can help prevent diseases like blight from affecting your tomato plants.
When planting garlic with tomatoes, it is best to interplant them rather than directly next to each other. This ensures that their strong scent permeates the surrounding area, maximizing their pest-repelling effects.
Onions: Great Companion Plants For Tomatoes
Onions, like garlic, belong to the allium family and offer similar benefits when planted alongside tomatoes. Onions release certain compounds into the soil that repel pests, such as aphids, moths, and cabbage loopers, which are known to attack tomato plants.
Placing onions in close proximity to tomatoes can create a barrier against these pests and help keep your tomato plants healthy. Additionally, onions possess natural anti-fungal and antibacterial properties, which can help prevent diseases from affecting your tomatoes.
When planting onions with tomatoes, it is essential to provide enough space between the plants for proper air circulation and to avoid shading the tomatoes. This way, both plants can thrive and support each other in your garden.
Lavender: Complementary Additions To Tomato Gardens
Lavender, with its lovely purple blossoms and delightful fragrance, can be a beautiful and complementary addition to your tomato garden. While it may not offer direct pest-repelling benefits like marigolds or garlic, lavender attracts beneficial insects, such as bees and butterflies, which aid in pollination.
Pollinators play a crucial role in the reproduction of tomatoes, ensuring the formation of healthy fruits. By planting lavender alongside your tomatoes, you can encourage the presence of these pollinators, leading to improved fruit set and yield.
In addition to attracting beneficial insects, lavender also benefits tomatoes by providing a calming and aromatic environment. It can help mask the scent of the tomatoes, making it harder for pests to locate them.
In Conclusion
Companion planting with tomatoes offers a range of benefits, including:
- Pest management
- Disease prevention
- Improved pollination
- Overall plant health
The inclusion of marigolds, garlic, onions, and lavender in your tomato garden can be a fantastic strategy to enhance the growth and productivity of your plants while reducing the need for chemical interventions.
Remember to consider the proper spacing and placement of these companion plants to optimize their benefits. Experimenting with different combinations and observing the results will help you find the ideal companions for your tomatoes.

Frequently Asked Questions
Can you plant onions close to tomato plants?
Yes, planting onions close to tomato plants can be beneficial as they act as natural pest repellents due to their strong odor, similar to garlic. Onions make excellent companion plants for tomatoes as they can help deter pests. However, if you are specifically dealing with thrips in your garden, it is recommended to avoid planting onions, leeks, or garlic near your tomatoes, as they may not be as effective against this particular pest.
What do you put around tomato plants?
One effective option for providing protection and insulation around tomato plants is to use dry grass clippings. These clippings can be applied as an organic lawn fertilizer, and when spread around the plants, they form a mat that safeguards the plants and helps to retain heat. Another suitable choice is straw, which serves as excellent mulch for tomatoes. It is important to avoid using hay, as it contains seeds that can potentially harm the plants.
Can I plant onions next to garlic?
While it may be tempting to plant onions and garlic side by side, it is best to refrain from doing so. Onions and garlic belong to the same Allium family and have similar requirements for growth, including full sun, well-drained soil, and regular watering. However, interplanting them can lead to competition for resources, stunted growth, and potential disease transmission. It is recommended to provide separate beds or containers for each plant to ensure optimum growth and avoid any potential negative effects.
What not to plant next to tomatoes?
One plant that should not be planted next to tomatoes is cabbage. This is because cabbage and tomatoes are both members of the brassica family and will compete for the same nutrients, resulting in stunted growth for the tomato plants. Another plant to avoid planting with tomatoes is corn, as it can also out-compete tomatoes for nutrients and hinder their growth.
