Asparagus Companion Plants & Bad Companion Plants for Asparagus

  • by

When planting asparagus, or any other vegetable, you should choose companion plants that get along well with one another. The asparagus plant lives for many years and thrives in the sunniest part of the yard. 

They achieve their maximum productivity after a period of two to three years, following which they continue to produce spears for another ten to fifteen years. This indicates that the plants that you choose to grow with your semi-permanent asparagus should enjoy sun exposure and be able to work around the asparagus.

Companions for asparagus may include plants that enrich the soil with nutrients, protect against diseases and pests, provide a home for beneficial insects, or help with the retention of water or the suppression of weed growth.

Here in this post, we’ll see some good companion plants for asparagus. We will also discuss plants you should avoid planting close to asparagus.

Good Companion plants for Asparagus

Tomatoes, basil, and parsley are likely to be the most successful companion plants for asparagus. The combination of all four of these plants creates a harmonious environment in the garden and provides a number of advantages. 

Other vegetables and fruits that work well when planted with asparagus include lettuce, peppers, spinach, eggplant, strawberries, and a wide variety of herbs.

Some flowers, or maybe just one, are a great addition to a garden with asparagus tops and ferns. When it comes to getting along with other plants in the garden, you may discover that asparagus is a rather friendly neighbor. I will not be able to describe every kind of vegetable, but I will discuss the most common companion for asparagus.

Basil and Parsely

Basil!

Due to the fact that it has a low maintenance need, basil and parsley are fantastic plants to have in your garden. The use of chemical pesticides may be minimized thanks to aromatic compounds’ ability to ward off not only the annoying asparagus beetle but also flies and mosquitoes. Both basil and parsley resist asparagus beetles, as well as other insects that may be harmful to any variety of asparagus, such as tomato hornworms. Additionally, basil and parsley encourage pollinators to all of their neighboring partner plants.

Tomatoes

Tomatoes

Tomato plants have a lot of the chemical solanine, which has been shown to deter the asparagus beetles that eat the young spears and fronds of asparagus plants. In the soil, however, asparagus discourages root-knot nematodes, which are pests that consume the root systems of nightshades. Similar properties may also be found in other nightshades, such as eggplants, which deter bugs from eating asparagus. You may get a big harvest from tomatoes, eggplants, and asparagus if you grow them all together.

Spinach and lettuce

Spinach

The shallow roots of spinach and lettuce never come into contact with the deeper roots of the asparagus plant. In addition, the rapid growth rate of spinach results in a restricted absorption of nutrients by the plant. From the moment the seeds germinate until the time they are harvested, they never remove a sufficient amount of minerals from the soil to do any harm to the asparagus.

Spinach and lettuce plants develop wide leaves that throw shade to prevent the soil from drying up and keeping it cool and wet. They grow quite well in the spaces between the rows of asparagus plants, and it may even be used as a trap crop to attract pests  

Beans

Beans are a very adaptable plant that can be planted alongside a broad range of other sorts of vegetables as well as other plants. This occurs as a result of the fact that beans and other legumes raise the level of nitrogen in the soil and provide essential nutrients to the plants that are growing in close proximity to them. In return, the development of other plants benefits from the growth of bean plants. You should feel free to plant asparagus next to beans.

Dills

The natural odor that dill plants give off helps to repel some of the most troublesome insects (spider mites and aphids) that are found in gardens. The cultivation of dill is simple, and the plant’s extensive taproots prevent it from competing with asparagus for nutrients in the first few inches of the soil. In the summer, when temperatures are at their highest, leaves that are longer offer shade and help prevent dill from running away. Learn more about companion plants for dills.

Rhubarb

Rhubarb

Many people are unaware that rhubarb leaves contain oxalic acid, a compound that is very effective for warding off insects that feed on leaves. Make sure to allow rhubarb lots of room to expand into, as this will prevent it from smothering other nearby plants as it grows. If you have pets, you should not grow rhubarb in the yard since the leaves of the plant are poisonous if eaten.

Grapes

The sandy, nutrient-poor soil that is essential for the growth of asparagus plants is also ideal for growing grapes. As a result of this, grapes have been used for many decades as companion plants for asparagus. However, due to the fact that both of these plants demand a significant amount of space, it requires some creative thinking to maintain them both in the same yard.

Grapes are climbing plants, thus they need to be taught to grow on a trellis so that they don’t suffocate other plants in the garden. Asparagus should be planted in a row on the side of your garden that faces away from the sun since this is the optimal location for growing leeks. During the hot afternoons, the grapes will provide a shadow over the asparagus plants, protecting them from the sun.

Strawberries

strawberries

Due to the fact that the roots of these two plants flourish at different depths, planting them together is an effective strategy. This indicates that both plants will be able to take use of the nutrients provided by the soil!

Additionally, they are early crops, which means that you are often able to harvest them at the start of the growing season for the majority of other crops.

Both asparagus and strawberries may reproduce on their own if given the chance. It is important to keep in mind that at some time you may need to maintain your pots or asparagus and strawberry beds by splitting the plants and transplanting them.

Nasturtium 

A wide variety of herbivorous insects that feed on vegetables are drawn to nasturtiums. Nasturtiums are preferred food for a variety of insects, including aphids, cabbage moths, spider mites, and leafhoppers. A lot of gardeners put nasturtiums in the spaces in between their rows to discourage pests like aphids and slugs from eating their more costly plants. 

Marigolds

Marigold plants, particularly French marigold cultivars, have a naturally unpleasant perfume that drives away the majority of bug pests. This may help you reduce the number of creepy crawlies and winged creatures in your yard. The plants also produce a phytotoxin that drives nematodes away from the soil, which makes them a particularly useful companion for asparagus.

What not plant with Asparagus

There are several plants that might pose a threat to the nutrients that your asparagus needs. This may have a significant influence on both the performance and crop production. It’s possible that asparagus beetles and other insects that consume asparagus will be attracted to other plants. Because of these factors, it is strongly recommended that you should not use the following plants as companions for your asparagus.

Carrots

Carrots

Carrots are vegetables with long roots that may reach deep into the ground, where they absorb as many nutrients as they can from the soil. Because they consume so many nutrients so rapidly, they pose a threat to the growth of your asparagus plants by robbing them of the minerals they need. In addition, carrots have the potential to attract carrot flies, which, if given the opportunity, would consume asparagus plants.

Potatoes

Potatoes

Potatoes demand a significant amount of nourishment, they sadly do not make good companion plants for asparagus. Your asparagus plants won’t have a chance of survival if you let these root vegetables use all of the nutrients in the soil first. Grow potatoes and asparagus in different beds if you want to harvest both crops successfully.

Allium

Allium

If you plant alliums like garlic, leeks, or onions near your asparagus, the plant’s development will be stunted. If you grow alliums alongside asparagus, you may expect your harvest to be on the smaller side, and that’s assuming the two plants don’t completely suffocate one another. You can grow allium with asparagus but plant them a good distance away from asparagus beds.

Final words

You can give your asparagus an advantage by surrounding it with the appropriate plants and maintaining a safe distance from it from the inappropriate ones. If you provide these plants with all they need for growth, you can be certain that you will be able to harvest and enjoy excellent asparagus produced in your own garden for many years to come. I really hope that you found this post to be informative.
