For 5 years, I have tried out companion planting. Trust me! It is one of the best gardening practices that involves growing certain plants together to enhance growth and protect against pests.
Green and red onions are essential crops to have in your garden. They can protect many common garden pests due to their strong “fragrant” smell. In addition to this, they improve soil conditions by releasing certain compounds that are of benefit to their companions.
It is important to know the RIGHT plants to choose from. Selecting the right companion plants can make a significant difference in the overall health and productivity of your garden.
9 Companion Plants for Green and Red Onions
You are reading this article because you seek answers! Well, I am here to help you out.
In my 5 years of practicing companion planting, I have found the 9 best companion plants you should try out with green and red onions. They coexist harmoniously with onions but also enhance their growth and flavor.
Read on to find out more.
1 – Beets
You can plant beets alongside green and red onions. The deep root system of beets helps loosen the soil, improving aeration and drainage, which is of utmost benefit to onions.
In addition to this, the different nutrient needs of beets and onions make it easy for them to coexist without the need to compete for soil resources.
2 – Lettuce
Lettuce and onions go hand in hand. Just as they are a perfect combo for salad and other meals, you can plant them alongside in your garden.
I discovered this combination while trying to solve my lettuce pest problem. Because onions release a strong scent which repels pests and rodents, they can form a protective shield around my lettuce as they both grow.
3 – Strawberries
Just like lettuce, they can be easily infested by pests and diseases. To solve this problem, plant strawberries alongside red and green onions.
Together, they will grow well, improving your soil condition and keeping pests away from your garden.
4 – Potatoes
Potatoes and onions are great companion plants. They grow well together without having to compete for the same nutrients.
Furthermore, potatoes have a different root structure from onions. With this, soil balance can be maintained.
The broad foliage of potatoes also provides shade that keeps the soil cool and inhibits weed growth. Onions can benefit from this as well.
5 – Carrot
Since carrots and onions have different nutrient needs, there will be less competition and enough room for both crops to thrive. In addition to this, the strong scent of onions repels carrot flies and other pests from your garden, creating a balanced and healthy garden ecosystem.
6 – Chamomile
The combination of herbs and onions forms a perfect garden bed. I have tried this out severally and loved the results. Trust me! The combination of chamomile and onions in your garden keeps pests away and creates a favorable condition for both crops to bring forth their best.
7 – Parsley
If you want to have a diverse garden environment, then incorporate parsley. Having it as a companion plant for green and red onions is the best choice you will ever make.
Both plants can thrive perfectly without exhausting the essential nutrients of your soil. Furthermore, parsley attracts insects like hoverflies and beetles, which are beneficial for pest control.
8 – Dill
I love dill because it enhances the growth and flavor of green and red onions. It is one of the best companion plants you should have with your onions. Great combo! Perfect garden experience!
9 – Eggplant
Eggplants also work well with onions. They protect your green and red onions from pests and also enhance their flavor. Therefore, these fall into the class of companion plants for your onions.
