How to Grow Mary Washington Asparagus Seeds

Start seeds indoors 8–10 weeks before your last frost date or sow directly outdoors in early spring once soil can be worked.
Choose a sunny location with deep, well-drained soil rich in organic matter.
Sow seeds ½ inch deep in seed trays or prepared beds.
Space seedlings 12–18 inches apart; rows should be spaced 3–4 feet apart for mature plants.
Keep soil consistently moist during germination.
Maintain soil temperatures between 70–75°F for best germination.
Seeds typically germinate within 14–21 days.
Transplant seedlings to a permanent bed once they are strong enough, as asparagus prefers undisturbed roots.

Grow in fertile, deeply cultivated soil enriched with compost or aged manure.
Feed with a balanced fertilizer in early spring and after harvest.
