Additional Information
SCIENTIFIC NAME: Asparagus officinalis
CULTURE: Asparagus is a long-lived perennial vegetable crop. With proper site selection, preparation, and care, it can thrive for 15 years or more. Asparagus prefers well-drained, fertile soil with a pH of 7.0 in full sun or part shade. Soil testing and bed preparation should be completed in the season prior to planting. May not perform well in warmer areas such as TX, MS, GA, LA, AL, or FL, as it may not become dormant, which is needed to prevent frost/freeze damage to crowns in winter months.
GROWING FROM SEEDS: Sow seeds indoors 12-14 weeks before desired transplant date. Sow 1 seed per 2" cell, ½-¾" deep. Germinate at 75-80°F (23-27°C) day, 65°F (18°C) night. Fertilize moderately as needed. After last frost, plant seedlings similarly to crowns, but use W-shaped furrow. Plant the seedlings in the middle point of the W to ensure better drainage. Gradually fill in furrow as plants grow.
PLANTING CROWNS: Crowns can be planted about 3-4 weeks prior to last average frost date. In a furrow 5-8" deep (shallower for heavy soils), 12" wide, place crowns with buds up and roots spread out, 8-14" apart in-row for green varieties and 6 - 8" apart in-row for purple varieties (closer spacing creates more slender spears). Allow 3-6' between rows. Cover crowns with 2-3" of soil at planting. As spears grow, gradually fill in furrow. Use caution when cultivating to avoid damaging crowns. Keep bed free of weeds (straw or leaf mulch works well) and irrigate regularly during establishment. Allow "ferns" to grow — do not cut until they senesce in the fall. Add compost or aged manure to the beds each fall or early spring.
HARVEST: One year after planting, beds can be harvested in spring for 7-10 days; 2 years after planting for 2-3 weeks. A normal harvest of 6 weeks is possible three years after planting. Marketable spears are approximately 7" in length and pencil-size in diameter. Harvest by bending spears over until they snap, or cut with knife just below soil surface. Store harvested spears upright at 36°F (2°C) and 95-100% relative humidity for up to 2 weeks.
SEED SPECS: SEEDS/LB.: Avg. 16,000.
PACKET: 30 seeds, sows approx. 25' depending on spacing.

Quick Facts
- Latin Name

- Days To Maturity
Average number of days from seeding date to harvest, within a specific crop group. If a transplanted crop: average number of days from transplant date. Not sure if crop is direct-seeded or transplanted? Check the Growing Information box for details. If crop can be both direct-seeded or transplanted, days to maturity refers to direct seeding. Days to maturity for all flowers and herbs is calculated from seeding date.
- Standard harvest begins third year after planting

Life Cycle
Plants can be Annuals (single growing season), Perennials (grow year after year), Tender Perennials (grow year after year in warmer climates; and in some cases when given special protection in colder climates), or Biennials (require two years to mature).

Hybrid Status
Hybrid: The offspring of a cross between two or more distinct parent lines, usually of same species, and selected for improved traits.
Open-pollinated: A non-hybrid variety that can reproduce itself in kind, demonstrating relatively stable traits from one generation to the next. - Hybrid (F1)
