What plants should not be planted near onions?
Planting onions can be a rewarding experience for any gardener. However, it is important to be aware of which plants should not be grown near onions. Certain plants can have negative effects on the growth and health of onions, affecting their flavor and overall yield. This article will explore the plants that should not be planted near onions and the reasons behind it.
1. Potatoes
Potatoes should never be planted near onions. These two vegetables belong to the same family, known as the nightshade family. When planted together, they can attract common pests such as onion flies and potato beetles. The proximity between potatoes and onions can also lead to the spread of diseases like blight, which can destroy both crops.
2. Beans
Beans, particularly any type of legume, should be kept away from onions. Onions have shallow roots and can easily be smothered by the dense foliage of legume plants. Additionally, beans add nitrogen to the soil, which onions do not require in excessive amounts. This excess nitrogen can lead to excessive leaf growth in onions, delaying bulb formation and reducing their size.
3. Peas
Similar to beans, peas belong to the legume family and can have similar negative effects on onions. The dense foliage of pea plants can outcompete onions for sunlight and inhibit their growth. Additionally, excessive nitrogen from pea plants can cause a delay in bulb formation and result in smaller onions.
4. Alliums
While it may seem counterintuitive, planting certain types of alliums near onions is actually not recommended. Alliums, such as garlic and shallots, can compete with onions for nutrients and space, hindering their growth. Additionally, planting different alliums close together increases the risk of spread for diseases that commonly affect this plant family.
5. Asparagus
Asparagus should not be planted near onions as they have different soil requirements. Asparagus requires a well-drained soil with a pH range of 6.0-7.0, whereas onions prefer a slightly acidic soil with a pH range of 5.5-6.5. Planting onions near asparagus can lead to soil imbalances, affecting the growth and overall health of both plants.
6. Sage
Sage is an herb that is often used in culinary dishes. However, it should not be planted near onions. Sage releases certain chemicals into the soil that can inhibit the growth of onions. These chemicals act as growth inhibitors, preventing onions from reaching their full potential.
Overall, it is important to be aware of which plants should not be planted near onions. By avoiding the companionship of certain plants, gardeners can ensure healthy and abundant onion crops. Taking these precautions will help maintain the flavor and yield of onions, enhancing the overall success of the garden.
Frequently Asked Questions
Can I plant onions near other vegetables?
It is not recommended to plant onions near certain vegetables. Onions release a compound called “allelopathic chemicals” that can inhibit the growth of nearby plants. Some plants that are affected by these chemicals include beans, peas, and asparagus. It is advisable to keep a distance of at least 4-6 feet between onions and these plants.
Can I plant onions near herbs?
Yes, onions can be planted near certain herbs. In fact, planting onions near herbs such as parsley, basil, and sage can actually be beneficial. Onions can help repel pests that commonly affect herbs, such as aphids and onion flies. Additionally, the strong aroma of onions can help mask the scent of herbs, making them less attractive to pests.
Should I avoid planting onions near root vegetables?
It is generally recommended to avoid planting onions near root vegetables. Onions are known to compete for nutrients in the soil, and planting them too close to root vegetables like carrots and radishes can result in stunted growth. To ensure optimal growth for both onions and root vegetables, it is best to keep a distance of at least 12 inches between them.
Will planting onions near tomatoes affect their flavor?
Yes, planting onions near tomatoes can affect the flavor of the tomatoes. Onions release sulfur compounds that can alter the taste of nearby plants. Tomatoes are particularly sensitive to these compounds, and planting onions too close to tomatoes can result in a pungent or unpleasant flavor. It is recommended to keep a distance of at least 4-6 feet between onions and tomatoes to avoid this flavor interference.
Can I plant onions near leafy greens?
Yes, onions can be planted near leafy greens such as lettuce and spinach. In fact, planting onions near these greens can help deter pests like aphids and slugs. The strong aroma of the onions acts as a natural repellent. However, it is important to note that onions can compete with leafy greens for nutrients. To ensure optimal growth for both, it is recommended to maintain a distance of at least 6-8 inches between the onion and the leafy greens.

Container gardening is an excellent option for growing herbs, vegetables, and even flowers, and it offers a great solution for urban dwellers or those with mobility issues.
Final Thoughts
In conclusion, it is important to consider the compatibility of onions with other plants when planning your garden. Onions can have both positive and negative effects on neighboring plants, depending on their species and growing conditions. It is advisable to keep a distance between onions and certain vegetables, such as beans and peas, to avoid inhibiting their growth.
