To ensure a bountiful harvest, choosing the best asparagus varieties for Michigan’s unique climate is paramount.
Selecting the Ideal Varieties for Michigan’s Climate
Michigan’s winters can be harsh, with fluctuating temperatures and occasional extreme cold. Therefore, selecting asparagus varieties that can withstand these conditions is crucial. The following varieties have proven their resilience in Michigan’s climate:
- Jersey Giant: A classic variety known for its thick, tender spears and high yield.

Considerations for Successful Cultivation
Beyond variety selection, several factors contribute to successful asparagus cultivation in Michigan:
Soil Preparation
Asparagus prefers well-drained, sandy loam soil with a pH between 6.0 and 6.8. Amend the soil with plenty of organic matter, such as compost or manure, to improve drainage and fertility.
Planting Time and Depth
Plant asparagus crowns in the spring or fall, spacing them 18-24 inches apart in rows 4-6 feet wide. Dig a trench 6-8 inches deep and place the crowns upside down, with the roots spread out. Cover the crowns with 2-3 inches of soil and gradually fill in the trench as the plants grow.
Mulching and Watering
Mulch around the asparagus plants with organic matter such as straw or hay to suppress weeds and retain moisture. Water the plants deeply and regularly, especially during hot, dry weather.
Fertilization
Fertilize asparagus plants annually in the spring with a balanced fertilizer. Avoid over-fertilizing, as it can promote excessive top growth at the expense of spear production.
Harvesting and Storage
Harvest asparagus spears when they reach 6-8 inches in length. Snap them off at the base of the plant and store them in the refrigerator for up to a week.
Companion Planting and Troubleshooting
Companion Planting
Asparagus benefits from companion planting with other vegetables such as tomatoes, basil, and marigolds. These plants can help deter pests and improve soil health.
Troubleshooting
Pests: Asparagus beetles are the most common pests. Control them by handpicking or using insecticidal soap.
Diseases: Fusarium wilt is a fungal disease that can cause plants to wilt and die. Prevent it by planting disease-resistant varieties and rotating crops.
