A Guide to Growing and Caring for Asparagus Companions

Asparagus, a delicate and nutritious vegetable, has been a staple in gardens for centuries. Cultivating a flourishing asparagus bed requires not only knowledge but also a strategic approach to ensure the best results. In this comprehensive guide, we delve into the art of growing and caring for asparagus companions, providing you with the insights needed to cultivate a bountiful harvest.

Choosing the Right Asparagus Varieties

Selecting the appropriate asparagus varieties is crucial for a successful harvest. Jersey Giant, Mary Washington, and Purple Passion are among the top choices for their adaptability and excellent yields. Consider your climate and soil conditions when making your selection, as these factors play a pivotal role in the asparagus cultivation process.

Site Selection and Preparation

Finding the Perfect Spot

For optimal growth, choose a site with well-drained soil and ample sunlight. Asparagus thrives in full sun, so select a location with at least six to eight hours of direct sunlight daily.

Soil Preparation

Prepare the soil by incorporating organic matter such as compost or well-rotted manure. This enhances soil fertility and provides the necessary nutrients for robust asparagus growth. Ensure the soil pH is between 6.0 and 7.0, creating an ideal environment for your asparagus companions.

Planting Asparagus Crowns

Timing Matters

Plant asparagus crowns in early spring, as soon as the soil is workable. This ensures that the crowns have sufficient time to establish themselves before the growing season kicks into full gear.

Proper Spacing

Space the crowns approximately 18 inches apart in rows that are three feet apart. Adequate spacing promotes air circulation, reducing the risk of diseases that can affect asparagus.

Planting Depth

Plant the crowns at a depth of 6 to 8 inches, covering them with soil gradually as they grow. This gradual covering encourages the development of a strong root system, a key factor in the long-term success of your asparagus bed.

Watering and Fertilizing

Consistent Moisture

Maintain consistent moisture throughout the growing season, especially during dry spells. Asparagus requires regular watering to ensure optimal development and prevent stress-induced issues.

Fertilization Schedule

Apply a balanced fertilizer in early spring before shoots emerge and again after the harvest season. This practice ensures that your asparagus receives the nutrients essential for vigorous growth and a substantial yield.

Companion Planting Strategies

Marrying Asparagus with Complementary Plants

Enhance the health and productivity of your asparagus bed through strategic companion planting. Tomatoes, basil, and parsley are excellent choices, as they deter pests that can harm asparagus while promoting a harmonious growth environment.

Avoiding Harmful Pairings

Steer clear of planting asparagus alongside onions and garlic, as these can impede the growth of asparagus. Their root systems may compete for nutrients, leading to suboptimal results.

Pest and Disease Management

Vigilant Monitoring

Regularly inspect your asparagus bed for signs of pests and diseases. Early detection allows for prompt intervention, preventing potential damage to your crop.

Natural Pest Deterrents

Encourage natural predators like ladybugs and lacewings to thrive in your garden, as they are effective in controlling aphids and other common pests. This eco-friendly approach minimizes the need for chemical interventions.

Harvesting and Storage

Patience Pays Off

Resist the temptation to harvest asparagus during the first two years, allowing the plants to establish a robust root system. Once established, you can begin harvesting in the third year, snapping or cutting spears at ground level when they reach 6 to 8 inches in height.

Storing Fresh Asparagus

For optimal freshness, store harvested asparagus in the refrigerator. Trim the ends and place the spears upright in a container with water, covering them with a plastic bag to maintain moisture.


Cultivating a thriving asparagus bed is a rewarding endeavor that requires careful planning and execution. By choosing the right varieties, preparing the soil adequately, and implementing strategic companion planting, you can ensure a bountiful harvest year after year.

Stay vigilant against pests and diseases, and follow proper harvesting and storage practices to savor the delectable flavor of homegrown asparagus.
