Growing Asparagus in Australia: The Complete Guide
Asparagus is a moderate perennial vegetable to grow, needing full sun with regular watering.
Asparagus is one of the moderate additions to a home garden, and this article walks through everything behind our one-page printable guide in a bit more depth.
Trench planting
Spread the crown over a mound at the base of a trench, then backfill gradually as spears emerge through the season — rather than filling all at once.
Getting Asparagus Into the Ground
Method — dig a 20cm trench, mound soil, spread the crown roots, backfill gradually as shoots grow. Soil — deep, free-draining, weed-free. Asparagus resents competition and waterlogging. Timing — plant dormant crowns in early spring.
Day-to-Day Care
A few things matter most here:
- Don't harvest in the first two years — let ferns grow to build the crown.
- Water well through the growing season, especially while establishing.
- Feed generously with compost or aged manure each spring.
- Cut ferns back to ground level once they yellow in autumn.
What Can Go Wrong
The key things to get right:
- Asparagus beetle — strips foliage; hand-pick or net during active feeding.
- Crown rot — from waterlogged soil; ensure sharp drainage.
- Rust — orange streaks on ferns; choose resistant varieties.
- Weed competition — shallow roots; hand-weed rather than dig.
Harvest and Storage
Signs — spears reach 15–20cm before tips begin to open. Method — snap or cut at soil level; harvest 4–6 weeks in year three, longer after. Curing — none needed — use promptly for best flavour. Storage — fridge, stems in water, up to a week. Freezes well blanched.
