The Ultimate Guide To Companion Planting With Onions

The Ultimate Guide to Companion Planting with Onions

Onions are a staple in many gardens, and for good reason. They're delicious, versatile, and relatively easy to grow. But did you know that companion planting can help you get even more out of your onions?

Companion planting is the practice of planting different types of plants together in a way that benefits both plants. Some plants help each other by attracting beneficial insects, deterring pests, or improving the soil.

In the case of onions, there are a number of companion plants that can help them thrive. Here are some of the best:

• Carrots: Carrots and onions are a classic companion plant combo. The strong scent of the onions helps to repel carrot fly larvae, while the carrots help to improve the flavor of the onions.
• Beets: Beets and onions are another great pair. The beets help to draw nitrogen from the soil, which benefits the onions. The onions, in turn, help to repel pests that can damage beets.
• Lettuce: Lettuce and onions are both cool-season crops that can be planted together. They have similar growing requirements, so they won't compete for resources. Plus, the lettuce helps to shade the onions' roots, which can help to prevent them from drying out.
• Strawberries: Strawberries and onions are a surprising but effective companion plant combination. The onions help to repel pests that can damage strawberries, while the strawberries help to improve the flavor of the onions.
• Tomatoes: Tomatoes and onions are another great pair. The onions help to repel tomato hornworms, while the tomatoes help to improve the flavor of the onions.
• Swiss chard: Swiss chard and onions are a good choice for companion planting because they have different water needs. The Swiss chard needs more water, while the onions need less. This means that you can water each plant according to its needs without overwatering or underwatering either one.
• Marigolds: Marigolds are not edible, but they are a great companion plant for onions. The marigolds help to repel pests that can damage onions, such as aphids, beetles, and root maggots.

In addition to these plants, there are a few that you should avoid planting near onions. These include:

• Peas: Peas and onions compete for nitrogen, so they should not be planted together.
• Beans: Beans and onions can stunt each other's growth.
