Carrots and beets are two of the most popular root vegetables grown in home gardens. They are easy to grow and can be harvested throughout the growing season. However, as with any plant, they can be prone to pests and diseases. One way to naturally protect them is by planting companion plants that will help repel pests, attract beneficial insects, and improve soil health. In this guide, we will explore some of the best companion plants for carrots and beets.

The Best Companion Plants for Carrots and Beets

1. Onions and Garlic

Onions and garlic are great companions for carrots and beets. They repel pests such as carrot flies and aphids, which can damage the root vegetables. Additionally, they have natural fungicidal properties that can help prevent fungal diseases such as damping off.

When planting onions and garlic, make sure to space them out so that they do not compete with the root vegetables for nutrients. Plant them in between the rows of carrots and beets or in nearby beds.

2. Beans and Peas

Beans and peas are legumes that fix nitrogen in the soil. This means they take nitrogen from the air and convert it into a form that other plants can use. Carrots and beets are heavy feeders, so adding nitrogen to the soil can help them grow stronger and healthier.

Plant beans and peas near carrots and beets or interplant them in the same row. Make sure to provide support for climbing varieties.

3. Lettuce and Spinach

Lettuce and spinach are cool-season crops that grow well with carrots and beets. They have shallow roots, which means they won't compete with the root vegetables for nutrients. Additionally, they provide shade to the soil, which can help keep it cool and moist.

Plant lettuce and spinach in between the rows of carrots and beets or in nearby beds. Make sure to harvest them before they get too big and shading out the root vegetables.

4. Nasturtiums

Nasturtiums are beautiful flowers that attract beneficial insects such as ladybugs and hoverflies. These insects feed on pests such as aphids and caterpillars, which can damage the root vegetables. Additionally, nasturtiums have a strong scent that repels pests such as squash bugs and whiteflies.

Plant nasturtiums near carrots and beets or interplant them in the same row. They prefer full sun but can tolerate some shade.

5. Marigolds

Marigolds are another flower that attracts beneficial insects and repels pests. They contain a natural chemical called thiophene, which repels nematodes, a type of pest that can damage the root vegetables. Additionally, marigolds have a strong scent that can mask the scent of the root vegetables, making them harder for pests to find.

Plant marigolds in between the rows of carrots and beets or in nearby beds. They prefer full sun but can tolerate some shade.

Other Tips for Companion Planting

1. Rotate Your Crops

Rotating your crops is important for preventing soil-borne diseases and pests. Avoid planting carrots and beets in the same spot every year. Instead, rotate them to a different bed or section of your garden.

2. Avoid Planting Brassicas

Brassicas such as broccoli, cauliflower, and cabbage are not good companions for carrots and beets. They are heavy feeders and can attract pests such as cabbage worms and root maggots.

3. Choose Plants That Have Similar Watering Needs

When planting companion plants, make sure to choose plants that have similar watering needs. Carrots and beets prefer well-drained soil that is moist but not waterlogged. Avoid planting them with plants that require a lot of water or have different watering needs.

4. Mulch Your Garden

Mulching your garden can help conserve moisture and suppress weeds. Use organic materials such as straw, leaves, or grass clippings. Avoid using plastic mulch, which can create a barrier that prevents water and air from reaching the roots.
