Asparagus is a long-lived perennial that takes 2-3 years to establish but then produces harvests for 15-20 years or more. It requires patience upfront but rewards with decades of spring spears. Male crowns are more productive than female plants as they don't waste energy on berry production. One of the most rewarding investments in any Australian home garden.

Pro Tips

  • Afternoon shade from taller plants or shade cloth beneficial

Harvesting Asparagus

When ready: Spears 15-20cm tall with tight, compact tips. Harvest before tips begin to open or 'fern out'. Thickness of a pencil or larger.

How to harvest: Snap spears at soil level by bending gently. They break at the natural weak point. Alternatively, cut with a sharp knife 2cm below soil surface. Harvest every 1-2 days during peak season.
