Growing Tips

  • Long-term investment — plant crowns for harvest in year 2–3.
  • Don't harvest at all the first year.
  • Plant in a dedicated permanent bed — asparagus lives 20+ years.
  • Stop harvesting when spears become thin.
  • Weed early and often.

Common Mistakes

  • Harvesting the first year — weakens the plant.
  • Moving the bed.
  • Cutting all spears — some must fern to feed roots.
  • Planting in heavy clay.

Companion Planting
