What Grows Well With Asparagus: Maximizing Your Asparagus With he Perfect Companions

Perennial gardening is a sustainable and effortless way to cultivate your crops. Unlike annual plants, perennials replenish themselves year after year, with minimal effort required on your part. If you’re considering creating a perennial garden, planting asparagus is a fantastic choice. However, to maximize your asparagus harvest, it’s essential to select suitable asparagus companion plants.

Asparagus, with its delicate leaves and stalks emerging from the soil in the spring, is a perennial plant that offers multiple harvests over several years. While it was once classified in the same family as onions and lilies (Allium), it now has its own family (Asparagaceae) within the order Asparagales, which also includes orchids and plants from the aster family.

What Does Companion Planting Involve?

Companion planting is an age-old technique in which farmers strategically choose specific crops to grow together in a garden to achieve various benefits. Companion plants can enhance crop yields, repel pests, attract beneficial insects, and even improve soil nutrient levels. It’s a system of mutual support and cooperation that mirrors natural ecosystems.

One classic example of companion planting is the “three sisters” method practiced by indigenous tribes. They plant beans, corn, and squash together. The corn provides support for the climbing beans and shade for both beans and squash. Beans enrich the soil with nitrogen and aid in the growth of corn and squash. Squash acts as a deterrent for pests and prevents weed growth. This interconnected system demonstrates the essence of companion planting and its ability to create a harmonious micro-ecosystem.

By selecting the right plants as companions, you can create a beneficial system for your asparagus. Apart from providing essential nutrients and monitoring pests, you can allow your plants to thrive together without much intervention. This principle applies to asparagus companion planting as well. By choosing companions like tomatoes and avoiding garlic and potatoes in your asparagus bed, you can achieve a bountiful harvest while keeping asparagus beetles at bay.

Ideal Plants To Grow Alongside Asparagus

Tomatoes

When it comes to asparagus companion planting, tomatoes are one of the most well-known and beneficial options. Asparagus and tomatoes thrive symbiotically. Tomato plants release solanine chemicals into the soil, repelling asparagus beetles. On the flip side, asparagus repels nematodes that can harm tomato roots. By planting tomatoes alongside asparagus, you can enjoy a healthy asparagus harvest while also safeguarding your tomatoes.

Eggplants

Similarly, eggplants, as part of the nightshade family, make excellent companions for asparagus. Planting tomatoes and eggplants in the area where you harvested asparagus stalks in early spring, along with extra compost to boost nutrient levels, can support both crops.

Herbs

Certain herbs can also aid in the growth of asparagus. Basil and parsley, for instance, attract beneficial insects while repelling asparagus beetles. Basil is particularly effective at deterring tomato hornworms and attracting pollinators. Since basil and parsley have similar moisture requirements, they can be conveniently planted side by side. This arrangement, combined with tomatoes, repels insects averse to the aromatic oils of these herbs while attracting insects that contribute to your garden’s health.

Cilantro and dill, with their shallow root systems, make great companions for asparagus. They appreciate the shade provided by asparagus plants and can be planted in rows at the other end of your asparagus bed. These herbs attract pollinators that help asparagus flowers produce seeds. In turn, these pollinators attract birds that prey on pests, creating a mutually beneficial environment.

Flowers

Various flowers, especially those from the aster family, are excellent companions for asparagus.

Petunias, marigolds, and nasturtiums help deter asparagus beetles and other pests.
Marigolds repel whiteflies, aphids, and nematodes, while petunias repel aphids.
Nasturtiums, with their vibrant flowers, can trap pests that might target asparagus fronds.
Comfrey, in addition to attracting pollinators, enriches the soil when planted in an asparagus garden.

All these flowers attract pollinators and some can even be consumed, providing an edible and visually appealing garden that fosters the right balance of insects.

Strawberries

If you prefer intensive planting, strawberries are an ideal companion for asparagus. Just ensure that your asparagus is planted about six inches deeper than usual to prevent root competition between the two plants. Strawberries act as ground cover and suppress weeds, which benefits asparagus. However, avoid planting strawberries and tomatoes together, as strawberries continue to grow and spread, unlike tomatoes.

Spinach, lettuce, and beets

Spinach, lettuce, and beets are also compatible with asparagus. These shallow-rooted plants occupy minimal space and have short lifecycles, which means they won’t interfere with the deep roots of asparagus. By planting these vegetables alongside the aforementioned flowers and herbs, you can minimize insect pests and enjoy an abundant supply of greens for your meals. Additionally, leafy greens are excellent companions for marigolds, which deters nematodes.

Opinions

While asparagus was historically grown alongside grapes during the Colonial era, opinions on their companionship vary today. Some argue that their shared preference for low-quality soil makes them suitable companions. However, others believe the large size of both plants may lead to difficulties in maintaining a productive asparagus garden. Grapevines require support for their vines, which might result in interference with asparagus growth. Unlike tomatoes, grapevines are long-lasting. However, if you’re feeling adventurous, you can experiment with planting them together, but be prepared for potential challenges.

Since asparagus roots grow deep and take time to develop, it’s advisable to plant them near shallow-rooted plants. Some of the companions mentioned earlier, such as herbs and flowers with deeper roots, may be better suited for the perimeter of your raised or in-ground asparagus garden. By planning your vegetable garden bed and incorporating borders of flowers, herbs, and nightshades, you can create an optimal environment for your asparagus to flourish.

Plants To Avoid Planting Alongside Asparagus

To ensure the health and productivity of your asparagus, it’s crucial to avoid planting it near alliums. Alliums, including onions, leeks, shallots, garlic, chives, wild onions, and ramps, hinder asparagus growth. These plants consume significant nutrients and take an extended period to mature. Their robust root systems can disturb the slow growth of asparagus, resulting in stunted stalks or a lack of growth altogether.

Potatoes are also incompatible with asparagus due to their shared dependency on deep root sections. Both plants require ample space for root development and have longer growth cycles. Similarly, carrots and asparagus don’t make good companions since carrots need deeper roots and don’t appreciate being planted near herbs like dill, which is beloved by asparagus.

Avoid planting any deeply rooted plants near asparagus, as they will compete for space and resources. Plants that take a long time to mature, like asparagus, should also be avoided as companions. By refraining from planting alliums and other deep-rooted crops, you can prevent stunted growth and ensure a thriving asparagus bed.

If you wish to grow potatoes, consider creating a separate potato tower in a different area of your farm or garden. This segregation will prevent competition and enable each plant to flourish independently.

Frequently Asked Questions

Q: Can I plant strawberries and asparagus together?

A: Absolutely! Asparagus and strawberries are compatible and make excellent companions. However, ensure that your asparagus roots are buried about a foot below the soil before interplanting strawberries. This will prevent root competition and allow both plants to thrive.

Q: Can I plant asparagus with other vegetables?

A: Many vegetables can happily coexist with asparagus. Lettuce, beets, spinach, and other shallow-rooted plants are compatible because they won’t compete with the deep roots of asparagus. Additionally, these crops complete their lifecycle before they can deplete nutrients from your asparagus plant.

By selecting the right companions, your asparagus can thrive and provide you with a bountiful harvest year after year. Incorporate these tips into your gardening routine, and watch your asparagus garden flourish with the power of companion planting. Happy planting!
