Did You Know?
1. Hemp: Did you know that planting hemp alongside onions can help repel some common pests, such as aphids and onion maggots? This natural companion plant not only provides a protective barrier but can also attract beneficial insects, such as ladybugs, that feed on harmful pests.
2. Beets: Onions and beets have a symbiotic relationship when planted together. While onions deter pests like aphids and onion flies, beets release organic compounds into the soil that help suppress weeds, creating a beneficial environment for both crops.
3. Chamomile: Planting chamomile near onions can result in increased onion yield and improved flavor. Chamomile helps repel onion flies and pests due to its strong aroma, while its shallow root system loosens the soil, aiding in nutrient absorption.
4. Lettuce: When onions and lettuce are companion planted, they can mutually benefit from each other. Onions help deter pests like slugs and snails that often damage lettuce leaves, while lettuce provides a shade cover that helps keep the onion bulbs cool and prevents them from bolting prematurely.
5. Nasturtiums: Nasturtiums make excellent companions for onions as they attract predatory insects that feed on onion pests. Additionally, their brightly colored flowers can help attract pollinators like bees and butterflies, benefiting both crops by increasing overall pollination rates.
Onions As Pest Deterrents
Onions, with their pungent odor and strong taste, have long been known to deter certain pests from attacking nearby plants. One common example is when onions are planted with carrots, which can help deter carrot root fly and onion fly. These pests are attracted to the smell of carrots and onions, but when planted together, the strong scent of the onions confuses them and keeps them away. This natural insect repellent can help protect your carrot and onion crops from being decimated by these pests.
Other pests that can be deterred by planting onions with specific companion plants include aphids and beetles. Marigolds, known for their bright and vibrant blooms, also have the ability to repel these pests. By planting marigolds next to your onion crop, you can create a natural barrier that keeps these insects at bay. The strong smell of the onions combined with the pungent aroma of marigolds is highly effective in deterring these pests, providing a safe and chemical-free solution for pest control in your garden.
Beneficial Pairings For Onions
While there are some plants that may not thrive when planted with onions, there are also several beneficial pairings that can help improve growth and yield for both plants.
-
Planting onions alongside tomatoes, beets, and lettuce can result in beneficial outcomes.
-
Onions act as natural pest deterrents for these crops, keeping common pests such as aphids, beetles, and rodents away.
-
Additionally, the combination of the plants can enhance the flavor of the vegetables, making them even more enjoyable to eat.
Cucumbers and onions, though they both belong to the root vegetable category, can also be planted together without any negative effects.
-
Since they have different nutrient requirements, they do not compete for resources, allowing both plants to flourish.
-
This companion planting also helps to create a diverse and visually appealing garden.
Incompatible Plants For Onions
Although onions can be planted alongside many plants, certain vegetables, such as peas, beans, and asparagus, should not be planted together with them. This is because these plants have different soil pH and moisture preferences, which can negatively affect the growth and development of onions. Therefore, it is recommended to separate these crops in order to ensure the maximum growth potential of each.
Onions And Pest Control
In addition to their ability to deter pests from attacking companion plants, onions also play a crucial role in overall pest control in the garden. By deterring pests from infesting nearby crops, onions indirectly protect other vegetables and fruits from potential damage.
For example, planting onions near a strawberry patch can keep pests away from the strawberries, ensuring a healthier and more bountiful harvest.
Onions also act as a deterrent for insects and rodents that may munch on lettuce leaves or damage parsnips. Their strong odor and taste confuse these pests, making them less likely to approach and attack these crops. By strategically planting onions in proximity to these vulnerable vegetables, you can create a barrier that helps protect them from harm.
Enhancing Flavor And Yield With Onion Companions
Not only do companion plants help deter pests and protect crops, but they can also enhance the flavor and yield of the onions themselves. Certain companion plants, such as chamomile, parsley, dill, and savory, can boost the flavor and growth of the onions when planted nearby.
- Chamomile, when grown alongside onions, has been known to enhance the flavor of the onions, adding a subtle floral note to their taste.
- Similarly, parsley can have the same benefits as planting onions with carrots, as it helps to deter pests and enhances the overall flavor of the onions.
Dill and onions make excellent companions, both in the garden and in the kitchen. When planted together, they enhance each other’s flavors, providing a harmonious combination that can elevate any dish. Additionally, growing onions near savory helps make them grow larger and more flavorful, giving you a more satisfying harvest.
In summary, onions have the potential to serve as excellent companion plants in the garden. They act as natural pest deterrents, protect neighboring crops from attacks, and can enhance the flavor and yield of the onions themselves. By carefully selecting and pairing onions with compatible plants, you can create a thriving and vibrant garden that is both beautiful and productive.
- Companion plants can enhance the flavor and growth of onions.
- Chamomile adds a subtle floral note to the taste of onions.
- Parsley deters pests and enhances the overall flavor of onions.

Frequently Asked Questions
What should you not plant onions next to?
While onions have many beneficial qualities as planting companions, it is best to avoid planting them next to peas, pole beans, bush beans, and asparagus. These crops may not thrive when in close proximity due to incompatible growth patterns or potential competition for nutrients in the soil. Therefore, it is recommended to give these plants their own designated areas to ensure optimal growth and productivity.
Can onions and cucumbers be planted together?
Yes, onions and cucumbers make excellent companions in the garden. The allium family, to which onions belong, emits a distinct aroma that deters pests from attacking cucumbers. This makes them perfect for planting together, as the onion scent serves as a natural pest repellent for the cucumber plants. Additionally, low-growing chives, another member of the allium family, can be planted beneath the cucumber plants, providing further pest protection while also enhancing the flavors of cucumber salads.
What onions grow fast?
One type of onion that grows fast is the ‘Walla Walla Sweet’ variety. These onions are known for their quick growth, reaching maturity in just 90 days. Not only do they grow fast, but they also produce sweet bulbs that can weigh up to two pounds each. With their crunchy white flesh and mild taste, ‘Walla Walla Sweet’ onions are a popular choice for those who are looking for a flavorful and fast-growing onion option.
Can you plant zucchini and onions together?
Yes, planting zucchini and onions together can be a smart choice. Zucchini plants have large leaves that can provide shade for onions, helping to protect the soil from erosion. Additionally, both zucchini and onions require minimal growing space, making them compatible companions in the garden. By planting them together, you can maximize space and create a beneficial environment for both plants to thrive.
