In this guide, we'll explore some of the best companion plants for broccoli and cauliflower and how to use them.

The Best Companion Plants for Broccoli and Cauliflower

Dill is a natural insect repellent that can help deter pests like aphids and cabbage loopers. Additionally, it attracts beneficial insects like wasps and other parasitic insects that can help control pest populations.

To use dill as a companion plant, plant it near your broccoli and cauliflower plants. You can also use dill leaves to make a natural insecticide spray.

4. Borage

Borage is a great companion plant for broccoli and cauliflower because it attracts bees, which are essential for pollination. Additionally, borage has natural pest-repelling properties and can help deter pests like tomato hornworms and cabbage worms.

To use borage as a companion plant, plant it near your broccoli and cauliflower plants. You can also use the flowers and leaves in salads or as a garnish.

Other Tips for Successful Companion Planting

1. Choose plants that have similar growing requirements

When choosing companion plants for broccoli and cauliflower, it's important to select plants that have similar growing requirements. This will ensure that all of your plants are able to grow strong and healthy and that they won't compete for resources like water and nutrients.

Mulch can help retain moisture in the soil and prevent weeds from growing around your broccoli and cauliflower plants. This will help improve soil health and reduce the risk of disease.

Rotating your crops can help prevent soil-borne diseases and pests from building up in the soil. If you plant broccoli and cauliflower in the same spot every year, you may notice a decline in plant health over time. Instead, rotate your crops to different parts of your garden each year.
