Carrot Companion Plants: For The Most Success

My carrots have germinated!

It feels like an extra level of success this year.

Last year it was very dry when we made our garden, and everything struggled to grow. This year we’ve gotten beautiful rain and carrots are loving it.

I’ve grown carrots for many years, and found that good carrots depend a lot on healthy soil, and certain soil types. Storing carrots long-term is easy if you have a cool place to put them.

Growing your own carrots can be incredibly rewarding, but also a little frustrating sometimes.

Did you know that choosing the right companion plants can make a big difference in your garden’s success?

This is something that I am discovering, and I thought I would share with you as I am learning.

Certain plants can help your carrots not only by preventing pest issues, but also by improving soil health and even enhance flavor.

By planting companions like onions, radishes, and marigolds nearby, you can create a more resilient and productive garden.

Companion planting is all about the symbiotic relationships between different plants.

For instance, onions release a scent that repels carrot flies, one of the most common pests for carrots.

Meanwhile, radishes act as a trap crop, attracting pests away from your carrots and taking the brunt of the damage.

Marigolds bring their own magic to the mix by suppressing nematodes in the soil, which can harm carrot roots. These are a super companion plant for many different vegetables.

I started planting marigolds several years ago after learning how beneficial they were. Marigolds don’t smell great, but they repel certain pests.

3 Benefits of Companion Planting with Carrots

Companion planting carrots can lead to better pest control, improved soil health, and more efficient use of your garden space.

Pest Control

Pest control is the main reason many people start studying companion planting. Working together with nature to keep pests away from your garden will help you garden organically, and with less loss.

Carrots benefit significantly from companion plants that deter pests. Planting onions or leeks alongside carrots keep away carrot flies due to their strong scents.

Herbs like rosemary and sage as are good companions as well. These aromatic plants help mask the scent of carrots, lessening the risk of attracting pests.

Soil Improvement

Certain companion plants can enhance soil quality, benefiting carrots.

Leguminous plants like beans and peas fix nitrogen in the soil, a crucial nutrient for carrot growth. This natural enrichment can lead to stronger, healthier roots.

Additionally, deep-rooted companions like radishes can break up compacted soil, improving aeration and drainage.

This makes it easier for carrot roots to grow straight and long. Better soil conditions from these companion plants can result in higher yields and tastier carrots.

Spatial Efficiency

Using companion plants can maximize your garden’s space. By interplanting carrots with fast-growing crops like lettuce, radish and spinach, you can harvest these earlier, reducing competition for resources.

Vertical-growing companions such as tomatoes can be paired with low-growing carrots to optimize space. The varied canopy creates a natural shade, reducing weed growth and maintaining soil moisture.

Efficient use of garden space through companion planting can lead to more diverse and productive gardening.

13 of the Best Companion Plants for Carrots

Carrots thrive when grown alongside specific plants. These companions help by repelling pests, improving flavor, and enhancing growth.

Aromatic Herbs

Aromatic herbs like rosemary, sage, and thyme are excellent companion plants for carrots. These herbs can deter common carrot pests such as carrot flies.

Their strong scent confuses and repels these pests, reducing the chances of your carrot plants being affected.

Additionally, herbs can improve the soil quality around carrots.

They often attract beneficial insects like ladybugs and predatory wasps, which help keep harmful pests in check.

Plant these herbs near your carrots to create a more balanced and healthy garden ecosystem.

Leafy Greens

Leafy greens such as lettuce, spinach, and chard pair well with carrots.

These plants have shallow roots, allowing them to coexist with deeper-rooted carrots without competing for resources.

They also act as living mulch, keeping the soil moist and cool, benefiting carrot growth.

Moreover, these greens mature quickly and can be harvested early, making more space and light available for the slower-growing carrots.

This symbiotic relationship maximizes garden efficiency and yields.


Alliums, which include onions, garlic, and leeks, are beneficial companions for carrots.

Carrots are susceptible to carrot root fly, and the the pungent smell of these plants helps deter pests like carrot flies and aphids.

Carrots and alliums do not compete heavily for nutrients, making them excellent neighbors in the garden.

Planting alliums with carrots also improves the flavor and development of both crops. Alliums can help break up the soil, making it easier for carrot roots to grow straight and strong.


Legumes such as beans and peas are fantastic companions for carrots. They help enrich the soil by fixing nitrogen, an essential nutrient for carrot growth.

This natural fertilization reduces the need for additional soil amendments and promotes healthier carrot plants.

Additionally, legumes can act as a trellis for carrot greens, providing a support structure that keeps the carrot tops upright. This setup improves air circulation and reduces the risk of fungal diseases.

Plant legumes near your carrots to boost their growth and improve garden productivity.

Radishes (My Favorite option)

Radishes and carrots are ideal to plant together. Planting radishes alongside carrots helps to plant carrots seeds with correct spacing. Radishes are harvested relatively early, leaving space for the carrots to fill out and grow.


There is good reason that carrots love tomatoes. Carrots dislike heat, and tomatoes love it.

They can be interplanted as shade for carrots, while carrots deep tap roots help to being up nutrients from deep in the ground.

You do need to be careful to not plant the tomato plants too thickly, as this will prevent sunlight from reaching the carrots. Lack of sunshine will stunt carrot growth.

Plants To Avoid Companion Planting With Carrots

Avoid planting carrots with others of its family. Dill, Parsley, Celery and Cilantro are all part of the Apiaceae family, and should not be planted together,

They can attract the same pests, and are no help to each other. Also, certain types of these plants can cross pollinate. This is a problem if you are saving seeds on your homestead.

Carrots are a nutritious root vegetable to grow in the garden.

And the taste of a homegrown carrot does not even compare with one from the store. Planting these carrot companion plants will help you grow the heathiest food possible for you and your family.
