How to Select the Best Asparagus Plants and Crowns

[Stephen Albert]

Choosing high-quality asparagus plants or crowns is critical for establishing a long-lived, productive bed. The right selection ensures vigorous growth, thicker spears, and fewer pest or disease problems. Over more than 30 years of growing asparagus in my California garden, I’ve learned what to look for when purchasing or sourcing plants to maximize your harvest.

Step 1: Choose Between Crowns and Plants​

• Crowns: One- or two-year-old dormant roots; faster to establish and produce harvestable spears sooner.
• Seedlings/Young Plants: Offer variety selection but require more time before full harvest.

Step 2: Look for Healthy Crowns​

• Firm and Plump: Avoid shriveled or soft crowns, which indicate poor health.
• Good Roots: Roots should be moist, pliable, and free from rot or mold.
• Size Matters: One-year-old crowns with multiple buds are ideal for quicker establishment.

Step 3: Inspect Plants Carefully​

• Foliage: Look for vibrant green, pest-free leaves.
• Root System: Avoid plants with tangled, damaged, or dried-out roots.
• Disease Check: No signs of discoloration, lesions, or fungal growth.

Step 4: Choose the Right Variety​

• All-Male Hybrids: High-yielding, produce thicker spears, and fewer berries. Examples: ‘Jersey Knight,’ ‘Jersey Giant.’
• Heirloom or Mixed-Gender Varieties: Provide berries for seed saving but slightly lower yields.

Step 5: Source Reputable Suppliers​

• Purchase from local nurseries or trusted online suppliers specializing in asparagus.
• Avoid crowded or stressed plants, which may struggle to establish.

My Experience and Key Takeaways​

Selecting robust crowns and healthy young plants has consistently produced thicker, more abundant spears in my garden. Paying attention to root health, bud count, and variety ensures long-term productivity and reduces maintenance challenges.
