Onions (allium cepa) look like they belong in a garden bed, with their green flat leaves and rounded bulbs poking above the soil. But onions will also grow successfully in containers. Whether you choose to plant your onions in raised beds or containers, get ready to enjoy a variety of delicious flavors and uses for your home-grown onions.
Beans are a good match for onions. Onions help beans grow. Beans, like onions, also aid in the growth of other plants and benefit the soil.
Onions can be planted near beans in early spring or fall. Planting onions around your bean plants will help them grow faster and produce more yields than if you planted them alone.
The combination of beans and onions is beneficial for both the soil and your garden because they improve drainage and loosen clay soils while improving aeration by adding organic matter to sandy soils
Carrots and onions are a great pairing. They both help to improve soil quality, making them good for your garden overall. Carrots and onions also work together in the kitchen, creating a vibrant blend of flavors when cooked together. This works especially well if you’re cooking with garlic or other spices that complement these flavors, too. If you’re looking for ways to enjoy both carrots and onions in your diet without having to sacrifice taste or healthiness, consider growing some of each at home!
Peas are a good companion plant for onions. They grow well in the same soil as onions, and can be planted alongside onion plants in your garden. This is because both peas and onions are cool-season annuals that thrive in spring weather, but will die back when the summer heat arrives. Peas also provide an excellent source of nitrogen to nourish your onion plants throughout their growing season (1).
In addition to being a good companion plant for onions, there are several other reasons why you might want to consider planting peas with your onions:
- Peas only need 30 days from germination until harvest (2), so you can have fresh peas on hand all summer long!
- Although pea seeds cost more than onion seeds (this may be reflected by pricing at local hardware stores), once planted they will produce multiple harvests over a longer period of time than an onion bed would if harvested only once after two months’ growth–and since harvesting affects how many new leaves emerge from each plant, repeated harvests mean lots more leafy tops available for eating later on down the road! So growing peas along with your early crop of full-sized green ones might actually end up saving money over time because fewer plants would need replacing later on down there road
Garlic is a perennial plant that can be planted in the fall and harvested in the spring. It’s also a good companion plant for onions, so if you’re planning on planting onions, consider planting garlic as well. It’s easy to grow and will be ready to harvest before your onions are ready to pick. Garlic is high in protein and vitamins, so it’s both good for you and nutritious! The vitamin C content of garlic is higher than any other vegetable or fruit (except citrus fruits), with one clove containing over ten percent of your daily value of this nutrient! Garlic also contains allicin which has been shown to have antiviral properties and may help prevent cancer cells from multiplying.
Onions will do well with many plants. Onions will help strawberries grow. Onions will help strawberries grow better. Onions will help strawberries grow faster. Onions will help strawberries grow more.
Lettuce is a great companion for onions, because the two plants have similar needs. They are both sun-lovers and don’t mind being planted close together in the garden. Lettuce also has tall stalks that can help shade the soil around it, which is beneficial to the onion plant’s roots. As long as you keep the lettuce from getting too tall and competing with your onions, it will be a good companion plant for your garden. Onions will deter pests from attacking lettuce, keep them moist and warm during cooler weathers (both by emitting gases), and even help promote healthy growth of this crop!
Nasturtiums are a great companion plant for onions. Not only are they easy to grow, but they also do well in containers and flower beds. They make an excellent edible flower, with their leaves and flowers both being tasty additions to salads or soups. Nasturtiums are also very nutritious; this flowering herb is one of the few edible plants that contain vitamin C. In addition to providing vitamin C, nasturtiums have been found by researchers from Italy’s University of Pisa to have high levels of antioxidants that may help prevent cancer cells from forming
Roma tomatoes are a popular choice for the home gardener. They can be grown in containers and are very easy to grow, making them ideal for beginners. They can also be grown in raised beds or hanging baskets, making them perfect for urban gardeners with limited space.
Roma tomatoes are a small-fruited tomato that is best eaten when it’s ripe, as opposed to being canned or frozen. The taste of Romas varies depending on the variety you choose, but it will always be sweeter than other types of tomatoes like cherry tomatoes or beefsteak varieties due to its smaller size and lack of seeds found in larger varieties
Cabbage and Broccoli
Onions can be used in conjunction with cabbage and broccoli to help repel pests, keep the soil moist and loose, and keep it warm.
If you have an onion bed that is next to a cabbage or broccoli crop, you should be able to reap all of the benefits of these companion plants. The onion’s strong smell will help repel beetles from the other crops while also keeping those pesky pests away from your plants if they ever do show up on their own. Onions are also a great source of nitrogen for your soil; this means that they will help fertilize your garden as well as make sure that there is plenty of moisture available for both crops to grow in. Finally, onions will actually help keep soil warm so that seeds germinate faster in cold weather!
Cauliflower and Brussels sprouts
Cauliflower and Brussels sprouts can be grown with onions. The onions can be planted in the same bed, row or space as these vegetables, or they can share a pot together.
You will need to make sure that the different plants are spaced properly so that they have room to grow without crowding each other out.
Onions will do well with many plants.
Most gardeners and farmers consider onions to be an asset in the garden. Onions are not only good for your plants, but they are also kind to the soil, compost pile and compost bin.
Onions will help any crop grown after them because they:
- Improve the soil by adding nitrogen to it as they decompose.
- Prevent erosion by holding on to topsoil when watering or watering less often. They also reduce runoff during rain events by keeping moisture in the ground longer than other plants would do so alone.
- Build up humus in your garden beds over time through their decomposition process which helps improve drainage and water retention properties of soils that are otherwise poor due to compaction or sandy texture (which result in poor drainage)
For those who don’t want to use pesticides, onions are a great option for natural bug control. If you have any plants that are getting attacked from bugs, planting them near onion plants can help keep the insects at bay.
This is true of many types of insects, but leafhoppers and aphids are especially repelled by the onion scent. However, if you’re growing onions as a companion plant and trying to keep pests away from other crops, you need to be careful not to let your onions spread too far into the other plants’ territory! If they grow too close together, then it will only attract more bugs instead of scaring them off.
The same goes for cabbage worms—onion leaves repel cabbage worms, so interplanting them throughout your cabbage crop will help keep these pests at bay.
