Companion planting is a gardening technique that involves growing different plants together for mutual benefit. As the name suggests, companion planting involves selecting plants that are complementary to one another and that can work together to improve soil health, reduce pest problems, and increase yields.

One plant that is particularly well-suited for companion planting is the humble onion. In this article, we will explore the benefits of companion planting with onion and discuss some of the best practices for incorporating this versatile vegetable into your garden.

The Benefits of Companion Planting with Onion

Onions are beneficial in many ways when grown alongside other plants. Here are just a few of the benefits of companion planting with onion:

Improving Soil Health

Onions are known for their ability to absorb nutrients from the soil and make them available to other plants. They also have a deep root system that helps to break up compacted soil, allowing air and water to penetrate more easily. This means that by planting onions alongside other plants, you can improve the overall health of your soil, which in turn leads to healthier and more productive plants.

Repelling Pests

Onions are naturally repellent to many pests, including aphids, spider mites, and thrips. By planting onions alongside other plants, you can help to deter these pests and reduce the likelihood of an infestation. Additionally, some gardeners believe that the strong odor of onions can help to mask the scent of other plants, making them less attractive to pests.

Increase Yields

When planted alongside other vegetables, onions can help to increase yields by improving soil health and repelling pests. Additionally, onions are known for their ability to accumulate sulfur, which is an important nutrient for many plants. By planting onions alongside other vegetables, you can help to ensure that they have access to the sulfur they need to thrive.

Best Companion Plants for Onion

Now that we've discussed the benefits of companion planting with onion, let's take a look at some of the best companion plants to pair with this versatile vegetable.

Carrots

Onions and carrots are a classic combination in the garden, and for good reason. Carrots and onions complement each other well and can be grown together without any negative effects. Additionally, carrots are believed to help repel onion maggots, which can be a problem for onion plants.

Lettuce

Lettuce is another great companion plant for onion. The shallow root system of lettuce makes it a good choice to grow alongside onions, as it will not compete with them for nutrients. Additionally, lettuce is believed to help protect onions from thrips, a common garden pest.

Tomatoes

While onions and tomatoes might seem like an unlikely pairing, they actually work quite well together. Onions are believed to help repel tomato hornworms, a common pest that can wreak havoc on tomato plants. Additionally, tomatoes and onions both benefit from the improved soil health that comes with companion planting.

Peppers

Peppers and onions are a natural pairing, both in the kitchen and in the garden. Onions are believed to help repel aphids and spider mites, which can be a problem for pepper plants. Additionally, peppers and onions complement each other well in terms of flavor, making them a great combination for cooking.

Plant onions in between other plants

To get the most benefit from companion planting with onion, it's best to plant them in between other vegetables. This allows the onions to work their magic without competing too heavily with other plants for nutrients and resources.

Plant seedlings close together

When planting onion seedlings, it's important to plant them close together to maximize their impact. You can plant them as close as two inches apart, as they will not compete heavily with each other for resources.

To prevent soil-borne diseases from building up in your garden, it's important to rotate your crops each year. Avoid planting onions in the same spot for more than two years in a row, and consider rotating them with other alliums like garlic or shallots.
