Are you looking to grow asparagus companion plants in your garden but need help knowing where to start? Did you know that companion planting is an excellent way to make the most of your asparagus crop? Read on to find out the best companion plants to grow alongside asparagus and the benefits of doing so.

Companion Planting Basics

Companion planting is a gardening technique that encourages natural habitat development and benefits the plants grown together. While there is no one-size-fits-all approach to companion planting, it can be a great way to maximize your space and get the most out of your garden.

One of the ideal plants to use in companion planting is asparagus. Asparagus is a hardy, perennial vegetable that grows well in most home gardens. It produces spears in early spring and can be harvested for several months. Regarding companion planting with asparagus, there are a few essential tips to keep in mind.

First, it’s essential to choose companion plants that will provide shade for the asparagus, as too much direct sunlight can cause the spears to become challenging. Tomatoes, peppers, lettuce, and beans are all recommended as companion plants for asparagus, as they can provide partial shade and won’t compete for the same nutrients.

Herbs are also great for companion planting with asparagus, as they can help improve the spears’ flavor. Aromatic herbs like parsley, thyme, rosemary, and oregano can enhance the flavor of asparagus while also providing some natural pest control by deterring aphids that might feed on the spears.

Finally, flowers are also great companion plants for asparagus. Marigolds and nasturtiums are particularly beneficial, as they produce strong-smelling compounds that can help to repel pests and attract beneficial pollinators.

By combining the right companion plants with your asparagus patch, you can create a vibrant and productive garden that will provide you with fresh spears for months to come.

Asparagus Companion Plants

When gardening, one of the best ways to maximize your crop yield is to strategically pair what you’re planting. Asparagus is no exception! Asparagus requires companions to thrive, and several asparagus companion plants do a great job of providing support. These plants will help to reduce disease, provide essential nutrients for the asparagus, and even improve its taste.

Let’s look at some of the most popular asparagus companion plants.


Basil is an excellent companion plant for Asparagus. Paired together in the garden, they make an excellent addition to any landscape. Basil is known for its fragrant aroma and array of flavors. It is also an easy-to-grow herb that has many uses in the kitchen.

When planting basil with asparagus, it is best to plant basil near the base of the asparagus plant. This allows the roots of the basil plant to access the deeper soil near the roots of the asparagus plant. Additionally, the basil can help to block the sun from reaching the base of the asparagus plants, protecting them from the heat and keeping them cool. The basil also helps to keep the asparagus moist.

The basil helps to keep the asparagus plants healthy by providing nutrients to the soil. Basil plants can provide nitrogen, potassium, calcium, and magnesium to the soil, making it easier for the asparagus plants to grow. This also helps to keep the plants healthy and encourages growth.

Not only does basil benefit the asparagus plants nutritionally, but it also helps repel aphids, mites, slugs, and other pests. The pungent odor of the basil plant’s oils repels many common garden pests, helping to keep the asparagus plants free from damage.

In addition to repelling pests, basil also acts as a sacrificial plant. If a pest makes its way to the asparagus plants, the basil acts as a magnet, trapping the pest so that it does not damage the asparagus.

Overall, basil is an excellent companion plant to asparagus. Not only does it provide nutrition and protection from pests, but it also helps to keep the soil moist and the asparagus plants relaxed. Planting basil near asparagus is a great way to ensure a healthy, vibrant garden.


Tomatoes are a popular option when it comes to companion planting with asparagus. Tomatoes can help protect asparagus from the dreaded asparagus beetle, a common pest in many gardens. They also help keep soil temperatures cooler, which asparagus loves. The tomatoes will also benefit from the shade of the asparagus in the summer, keeping them cool and producing better fruit.

Tomatoes should be planted away from the asparagus, as the tomato vines can easily keep the asparagus from getting enough sunlight. Additionally, the roots of the tomatoes can spread out and compete with the asparagus for nutrients, so make sure to keep them at a distance from each other.

When planting tomatoes, choose varieties resistant to diseases, such as Roma and Big Boy. Plant them upright, instead of sprawling on the ground, to help keep the weeds away from the asparagus. Additionally, use tomato cages to keep the plants under control and less likely to spread.

Tomatoes and asparagus can also be grown together in a container garden. Make sure the container is large enough to allow for root growth. Also, be sure to use quality soil and feed the plants with a balanced fertilizer at least once a month. This will help to ensure that the tomatoes get the nutrients they need while keeping the asparagus healthy.

By carefully considering the types of tomatoes you plant, keeping them at a distance from the asparagus, and providing the right environment, you can enjoy a bounty of fresh tomatoes and asparagus this season!


Parsley is a great choice when it comes to choosing companion plants for asparagus. Parsley grows best in well-drained, nutrient-rich soil, and asparagus thrives in similar conditions. This is part of the reason that the two make such good companions. Additionally, parsley can help to trap moisture in the soil, which is beneficial for asparagus, as it needs ample moisture for optimal growth.

Parsley is a fast-growing and low-maintenance plant that can help to supplement soil nutrition for both plants. The presence of parsley also keeps the soil warm and soft, which helps to make root growth easier. Additionally, both plants’ shallow root systems help minimize competition for nutrients while helping to provide additional opportunities to retain moisture.

Parsley also plays a part in discouraging pests and protecting against disease. The firm, fragrant aroma of the leaves and oils produced by the plant can help to repel insects and other pests. The presence of parsley can also help to mask the smell of asparagus, which some pests find attractive. Additionally, parsley can help to break up the development of fungal diseases due to its antibacterial properties.

As with any companion plant, it’s essential to consider the sunlight available. Parsley prefers a spot that receives partial shade but also access to some direct sunlight. It’s also a good idea to check with your local USDA zone to determine if parsley can be grown successfully in your area.

Overall, parsley is an ideal companion for asparagus. With its natural pest repellent, disease prevention, and nutrient-rich properties, parsley can help to ensure that both plants thrive.


Celery is an excellent companion plant for asparagus. It is part of the same family, Apiaceae, and they share many similar characteristics. Celery is an easy-to-grow plant that requires little maintenance and provides nutritional benefits. Additionally, celery can provide a barrier against weeds, reducing the time spent weeding around asparagus. The tall, stiff celery stalks give any vegetable garden a lush, evergreen look and can even provide shade for asparagus during the hot summer months.

When planting celery alongside asparagus, it’s important to remember that celery prefers slightly alkaline soil, so adding a bit of lime to the area may be beneficial. An inch or two of mulch will help keep the soil moist and protect the celery from the sun. It’s also essential to keep the rows of celery and asparagus further apart than you usually would to avoid competition between the two vegetables.

Celery sometimes attracts certain garden pests, such as carrot rust flies and celery leaf miners. To keep these pests away, you can try companion plantings, such as planting onions, garlic, and other herbs between the celery and asparagus. Additionally, providing plenty of organic matter and avoiding excessive water will help deter pests. With the proper care and maintenance, you can enjoy celery and asparagus happily growing together in your vegetable garden!


Garlic is a reliable companion plant for asparagus due to its ability to repel insects and other pests. Garlic is also a great complement to asparagus in a culinary sense, so it’s an excellent choice for gardeners who want to maximize their space and get the most out of their garden. Garlic is best planted a few weeks before asparagus to give it enough time to become established before the asparagus is planted. Make sure to plant the garlic in full sun or at least partial sun and in a well-drained spot. Garlic tends to survive harsh winters, but you may need to mulch it in colder climates. As garlic sends out its new shoots and divides itself, it spreads and reproduces.

Garlic can also help ward off many pests who might like to snack on your asparagus, like aphids and cabbage worms. Garlic emits an odor many pests and animals can’t stand, deterring them from getting too close and destroying the asparagus crop. Garlic also helps to act as a natural fertilizer and can help to improve soil quality. Growing garlic alongside asparagus is a great way to get the best of both worlds, and it makes for a great addition to the vegetable garden.


Onions are a great companion plant for asparagus. If you’re looking to add some variety to your garden, onions are a great way to do so. They are also easy to grow and maintain, making them an ideal companion plant for asparagus. Onions can help protect your asparagus plants from pests and provide extra nutrition.

When planting onions with asparagus, make sure to keep them well apart. Onions are known to produce a strong odor, which can impact the flavor of the asparagus. If the onions are too close, the flavor of the asparagus may be affected. Make sure to provide plenty of space between the two plants.

Onions are also great for providing nutrition to the asparagus. Onions are rich in sulfur, which helps to enrich the soil with essential nutrients. This helps the asparagus absorb essential minerals better, leading to healthier and more flavorful asparagus stalks.

Onions also act as a natural repellent for pests. Growing onions alongside asparagus can help keep pests away and allow the asparagus to grow without the fear of being eaten.

Overall, onions are an excellent companion plant for asparagus. They can provide the extra nutrition, act as a natural pest repellent, and add variety to your garden. When growing onions alongside asparagus, remember to provide plenty of space between them to ensure the onion’s strong odor does not impact the asparagus.

Benefits of Growing Asparagus with Companion Plants

When included in a healthy garden landscape, asparagus often benefits from the companionship of other plants. The right companion plants can provide several benefits, including improved pest control, nutrient balance, and even higher yields.

One of the most beneficial benefits of companion planting with asparagus is pest control. Asparagus is a relatively low-maintenance crop that is not prone to many significant pests. However, certain companion plants can help keep away more aggressive pests like slugs and snails. Planting garlic, alliums, and other strong-smelling companion plants can help ward off these pesky critters and keep your asparagus thriving.

In addition to pest control, companion plants can benefit your asparagus crop. For example, certain herbs can be used to help boost the flavor of your asparagus. Parsley and dill, for example, can make your asparagus taste more affluent and more delicious. Asparagus also does well with leguminous plants, such as peas and beans, as these plants help increase nitrogen levels in the soil and improve overall soil fertility.

Regarding companion plants for asparagus, there are a few key considerations to bear in mind. As always, you must ensure the companion plants you choose are not aggressive competitors that could steal resources away from your asparagus crop. Any plants you choose should be spaced adequately to allow the asparagus plants to grow freely. Finally, ensure you rotate companion plants regularly to avoid pest and disease build-up in the soil.

Overall, companion planting is an effective and beneficial strategy for any asparagus gardener. By carefully selecting the right companion plants and rotating them regularly, you can help keep pests away, increase soil fertility, and boost the flavor of your asparagus crop.


Growing together has never been so rewarding! With companion planting, you don’t just get a few good ingredients to add to your meals. You get an entire garden full of dynamic relationships that create more robust flavors, more insect and disease resistance, and vibrant soil. The possibilities are endless.

Asparagus is a unique vegetable that grows best in the company of its companion plants. Basil, tomatoes, parsley, celery, garlic, and onions make great friends for asparagus; providing them with the nutrients and protection they need to thrive. Not to mention the abundance of flavors they bring to the table. So why not give your asparagus the companionship it deserves? With the right combination of companion plants, you can get the most out of your garden and save time and money. You can also bring extra flavor, color, and life to your garden. There’s no better way to get the most out of your garden. So get planting, and grow together with asparagus and its companions!
