Asparagus In The Spring
As the days grow longer and the soil begins to warm, one of the earliest vegetables to greet spring is asparagus. Known for its tender stalks and unique flavor, asparagus is a perennial favorite in both gardens and kitchens. Growing asparagus in the spring is a gratifying experience, whether you’re starting a new bed or enjoying the return of an established patch. Here’s how to make the most of asparagus season in your spring garden.
1. Understanding Asparagus as a Perennial
Unlike many vegetables, asparagus is a long-term commitment. Once planted, it can produce for 15 to 20 years with proper care. Spring is the peak season for harvesting, and also a good time to plant new crowns. While it takes a couple of years before new plants yield a full harvest, the wait is worth it.
2. Planting New Asparagus Crowns
If you’re starting fresh, early spring is the ideal time to plant asparagus crowns (one-year-old roots). Choose a sunny location with well-drained soil. Asparagus prefers slightly sandy soil with a pH between 6.5 and 7.5.
Prepare a trench about 6 to 8 inches deep and 12 to 18 inches wide. Space crowns 12 to 18 inches apart and spread their roots out evenly. Cover the crowns with 2 inches of soil and gradually fill in the trench as the plants grow. This helps the developing spears stay upright and encourages strong root development.
3. Caring for Established Beds
In established asparagus beds, spring is the time to clean up dead ferns from the previous season and apply a fresh layer of compost or well-rotted manure. This not only enriches the soil but also suppresses weeds and conserves moisture.
As soon as the soil temperature reaches about 50°F (10°C), spears begin to emerge. Keep an eye out, as they grow quickly. You’ll want to harvest when the spears are about 6 to 8 inches tall and before the tips start to open.
4. Harvesting Spring Asparagus
Harvest asparagus by cutting or snapping the spears just above the soil line. Be gentle to avoid damaging new shoots below the surface. For young beds in their second or third year, limit the harvest period to 2-4 weeks to allow the plants to build strength. Mature beds can be harvested for 6-8 weeks.
Stop harvesting once the spears become thin—this is a sign that the plant needs energy to regenerate. Let the remaining spears grow into ferns, which feed the crowns and ensure a healthy crop next year.
5. Weed and Water Management
Asparagus doesn’t compete well with weeds, so regular weeding is important. Apply a mulch layer to keep weeds at bay and retain soil moisture. Water consistently, especially during dry spells, as stressed plants will produce fewer, thinner spears.
Avoid using herbicides in asparagus beds, as the plants have shallow roots that are easily damaged.
6. Pests and Diseases
While asparagus is relatively low-maintenance, it can fall victim to pests like the asparagus beetle. These small, dark beetles and their larvae chew on spears and ferns. Hand-pick beetles or use organic insecticidal soap if needed. Keep beds clean and healthy to reduce disease risk.
Final Thoughts
Spring is a special time for asparagus growers. Whether you’re harvesting tender spears from a mature bed or planting new crowns, it’s the start of something delicious and enduring. With a little care and patience, your asparagus patch can become a springtime tradition, feeding your family and garden for years to come
