The Ultimate Onion Companion Planting Chart

Onions are a versatile vegetable that can be enjoyed in many different dishes. They are also relatively easy to grow, but there are a few things you can do to improve your chances of success. One of the most important things is to plant your onions with the right companion plants.

Companion planting is the practice of planting certain types of plants together to benefit each other. Some plants, for example, can help to repel pests or diseases, while others can improve the flavor or growth of their neighbors.

When it comes to onions, there are a number of great companion plants that you can choose from. Here are a few of the best:

• Beets: Beets are a good companion plant for onions because they help to repel pests like aphids and flea beetles. They also add minerals to the soil, which can benefit the growth of your onions.
• Broccoli, cabbage, cauliflower, kohlrabi, kale, and other brassicas: These plants are all susceptible to insect damage, so planting them near onions can help to deter pests. Onions also help to improve the flavor of brassicas.
• Cantaloupe, honeydew, watermelon, and other melons: Onions can help to repel pests that attack melons, such as cucumber beetles and squash bugs. They also help to improve the flavor of melons.
• Chamomile: Chamomile is a flowering plant that has insect-repelling properties. Planting it near onions can help to keep pests away. Chamomile also helps to improve the flavor of onions.
• Lettuce: Lettuce and onions are both cool-season crops that can be planted together. Lettuce helps to shade the soil around the onions, which helps to keep them cool and moist. Onions, on the other hand, help to repel pests that can damage lettuce.

In addition to these plants, there are a number of other companion plants that can be beneficial for onions. Some of these include:

• Carrots: Carrots and onions can be planted together because they have different root systems and do not compete for nutrients. Carrots also help to repel carrot fly, a pest that can damage onions.
• Cucumbers: Cucumbers and onions can be planted together because they have different water needs. Cucumbers prefer moist soil, while onions prefer well-drained soil. This way, each plant can get the moisture it needs without competing with the other.
• Herbs: Many herbs, such as basil, dill, and mint, can be beneficial companion plants for onions. These herbs help to repel pests and improve the flavor of onions.
• Peas: Peas and onions can be planted together because they help to fix nitrogen in the soil. This means that they can provide nitrogen for each other, which can help to improve their growth.
• Spinach: Spinach and onions can be planted together because they have different growing habits. Spinach grows quickly and matures early, while onions take longer to mature. This way, you can harvest spinach while you are waiting for your onions to grow.

Of course, there are also some plants that should not be planted near onions. These include:

• Beans: Beans and onions compete for the same nutrients, so planting them together can stunt their growth.
• Asparagus: Asparagus can release chemicals into the soil that can inhibit the growth of onions.
• Sage: Sage can inhibit the growth of onions.

It is important to note that these are just general guidelines. The best way to determine which companion plants are right for your garden is to experiment and see what works best for you.

Onions are a versatile vegetable that can be enjoyed in many different dishes. But did you know that the plants you grow near your onions can also affect their flavor and growth? That's where companion planting comes in.
