Asparagus is a delicious and nutritious vegetable that is a favorite among many gardeners. It is a perennial plant that can produce bountiful harvests for up to 20 years. Like any other plant, asparagus can benefit from companion planting, where certain plants are grown alongside it to enhance its growth, deter pests, and improve overall health. In this article, we will explore some of the best companion plants for asparagus.

Why Companion Planting is Beneficial

Companion planting is a gardening technique that involves growing compatible plants together to create a mutually beneficial environment. There are several reasons why companion planting is beneficial for asparagus:

  • Improved pest control: Some companion plants repel pests that commonly affect asparagus, such as asparagus beetles and nematodes. Planting these repellent plants alongside asparagus can help deter pests naturally.
  • Enhanced pollination: Certain companion plants attract pollinators like bees and butterflies, which can increase the chances of successful pollination for asparagus plants.
  • Soil improvement: Certain plants, known as nitrogen fixers, have the ability to convert atmospheric nitrogen into a form that can be easily absorbed by plants. Planting nitrogen-fixing plants near asparagus can help provide it with a natural source of nitrogen, which is essential for healthy growth.
  • Weed suppression: Some companion plants can help suppress weeds by shading the soil or releasing chemicals that inhibit weed growth. This can reduce competition for nutrients and water, benefiting the asparagus plants.

Companion Plants for Asparagus

Now that we understand the benefits of companion planting, let’s explore some of the best plants to grow alongside asparagus:


Tomatoes are excellent companion plants for asparagus. They repel asparagus beetles and provide shade to the asparagus ferns during hot summer months. Additionally, tomatoes are heavy feeders, which means they require lots of nutrients. Growing them alongside asparagus can help deplete excess nutrients from the soil, preventing them from becoming imbalanced.


Parsley is not only a delicious herb but also a great companion plant for asparagus. It attracts beneficial insects like hoverflies and parasitic wasps, which prey on common asparagus pests. Parsley also provides shade to the asparagus plants, helping to keep the soil cool and moist.


Marigolds are known for their ability to repel a wide range of pests, including nematodes, which can be harmful to asparagus. Planting marigolds around asparagus can help deter these pests, reducing the risk of damage to the asparagus plants.


Nasturtiums are lovely flowering plants that attract pollinators and repel aphids and other pests. By planting nasturtiums near asparagus, you can create a more diverse and balanced ecosystem in your garden, supporting the overall health and productivity of your asparagus plants.


Beans are nitrogen-fixing plants, meaning they have the ability to convert atmospheric nitrogen into a form that can be absorbed by plants. Planting beans near asparagus can help provide it with a natural source of nitrogen, promoting healthy growth. Additionally, beans can act as a living mulch, suppressing weeds and conserving soil moisture.


Companion planting is a valuable technique that can greatly benefit asparagus plants. By carefully selecting and growing compatible plants alongside asparagus, you can improve pest control, enhance pollination, improve soil health, and suppress weeds. Tomatoes, parsley, marigolds, nasturtiums, and beans are just a few examples of companion plants that can thrive alongside asparagus. Experiment with different combinations to find the best companion plants for your asparagus garden and enjoy a healthier and more productive harvest.
