Companion Plants for Cabbage and Broccoli

companion plants for cabbage and broccoli

Cabbage and broccoli are popular vegetables that are grown all over the world. They are both members of the Brassica family, which also includes cauliflower, kale, and Brussels sprouts. While they are both delicious and nutritious, they are also prone to certain pests and diseases. Companion planting is an excellent way to reduce the risk of these problems and improve the growth and yield of your cabbage and broccoli plants.

Why Use Companion Plants?

Companion planting involves growing different plants together that have a mutually beneficial relationship. The benefits of companion planting include:

1. Pest Control

By planting certain plants together, you can naturally repel pests that would otherwise damage your cabbage or broccoli plants. For example, planting marigolds alongside your cabbage or broccoli will help to deter aphids, flea beetles, and other pests.

2. Nutrient Cycling

Companion planting can also help to improve soil health by using nutrient cycling. Certain plants, such as legumes, fix nitrogen in the soil, which can be used by your cabbage and broccoli plants. Other plants, like comfrey, have deep roots that can bring up nutrients from deeper in the soil.

3. Attracting Beneficial Insects

Some companion plants can attract beneficial insects, such as bees and ladybugs, which will help to pollinate your cabbage and broccoli and control pest populations.
