Asparagus, Jersey Knight, Bare Root

Asparagus: Jersey Knight

Description:
Jersey Knight asparagus is a standout hybrid variety prized for its high yields, superior disease resistance, and robust, tender spears. Known for its ability to thrive in a variety of soils, including heavier clay types, Jersey Knight is a favorite for gardeners seeking a low-maintenance and productive asparagus crop. This variety is predominantly male, meaning it devotes more energy to spear production rather than seed development, resulting in larger and more abundant harvests.

Key Features:

• Type: Hybrid, predominantly male variety
• Flavor: Sweet and tender
• Spear Size: Large, thick, and deep green with purple-tinged tips
• Lifespan: Long-lived perennial, producing for 15–20 years with proper care
• Hardiness: Best in USDA zones 3–9

Growing Tips:

• Soil: Prefers well-draining, fertile soil with a slightly acidic to neutral pH (6.5–7.5). Thrives in heavier soils like clay when amended with organic matter.
• Light: Requires full sun for optimal growth and spear production.
• Planting:
  • Crowns: Plant dormant crowns in early spring, 6–8 inches deep and 12–18 inches apart in rows spaced 4–5 feet apart.
  • Seeds: Can be started indoors or direct sown, but crowns are preferred for quicker establishment.
• Watering: Keep soil consistently moist during the establishment phase. Mature plants tolerate occasional drought.
• Fertilization: Apply a balanced fertilizer in early spring and again after harvest to support healthy fern growth.
• Mulching: Use mulch to retain moisture, suppress weeds, and protect crowns from extreme temperatures.

Harvesting:

• Begin harvesting lightly in the second year after planting crowns (third year for plants started from seed).
• Harvest spears when they are 6–8 inches tall, cutting or snapping just above soil level.
• Stop harvesting by late spring or early summer to allow ferns to grow and recharge the plant for next year.

Why Grow Jersey Knight Asparagus?

• High Yields: Predominantly male plants focus on spear production, leading to larger harvests.
• Disease Resistance: Exceptional resistance to rust, crown rot, and fusarium, making it a reliable choice for challenging conditions.
• Adaptability: Performs well in a wide range of soil types, including heavier clay soils.
• Low Maintenance: Once established, Jersey Knight is long-lasting and requires minimal care.

Jersey Knight asparagus is a top-performing variety, ideal for gardeners who want a productive, durable, and delicious perennial vegetable in their garden.
