Growing Spring Onion in Australia: The Complete Guide
Spring Onion is an easy bulb & allium to grow, needing full–part sun with regular watering.
If you're thinking about adding spring onion to the homestead, here's the real detail behind our printable guide — what it actually takes to grow it well in an Australian garden.
Harvested before bulbing
Spring onions are simply pulled young, before a true bulb forms — a fast, low-effort crop that can be tucked into gaps between slower-growing vegetables.
Getting Spring Onion Into the Ground
Method — direct sow thickly in a short row or block. Soil — loose, well-drained, moderately fertile. Timing — sow year-round in mild zones for a continuous supply.
Day-to-Day Care
Worth paying attention to:
- Succession sow every few weeks for a steady harvest.
- Keep soil evenly moist.
- Harvest by pulling every second plant to let others size up.
- Feed lightly if growth looks slow.
What Can Go Wrong
Keep these points in mind:
- Onion thrips — silvery streaking; hose off.
- Rust — orange spotting; improve airflow.
- Damping off — young seedlings in wet, cool soil; avoid overwatering seedlings.
- Bolting — less of an issue since harvested young.
Harvest and Storage
Signs — usable from pencil-thickness onward. Method — pull by hand, whole plant. Curing — none needed. Storage — fridge crisper, about a week.
