Asparagus

When to plant asparagus in Australia

Plant asparagus crowns in winter — June to August in cool, arid and temperate zones, June to July in subtropical zones. Not recommended for tropical climates, since asparagus needs reliable winter chill to trigger spear production. Whichever zone, resist harvesting for the first two years while the crowns establish. From year three you'll get a proper harvest each spring, and a well-prepared bed can keep producing for 20 years or more.

Frequently asked

How long until asparagus is ready to harvest?

About two years to establish before any harvest at all. From year three, expect a reliable harvest each spring, and a well-prepared bed can keep producing for 20 years or more.

Can I grow asparagus in a tropical climate?

Not reliably — asparagus needs consistent winter chill to trigger proper spear production, which tropical climates like Darwin and Cairns don't provide.

How much space does asparagus need?

Crowns are typically spaced around 30cm apart within the row, with 120cm between rows to allow access for harvesting over its long life.

What pests affect asparagus?

Asparagus beetle is the main pest — handpick adults and larvae, and clear old fern growth at season's end to reduce overwintering sites.
