Leeks are the gentle giant of the allium family - milder than onions, easier than garlic, and more cold-hardy than both. They occupy the garden for a long time (5-6 months from seed) but require minimal attention once established. Excellent for cool-season gardens and highly adaptable across Australian zones. A staple of winter soups, gratins, and quiches.

How to Grow Leek in Arid / Semi-Arid Australia
When to Plant
March to August. Autumn-winter growing. Need consistent irrigation.
- Soil
- Rich, well-drained soil with plenty of organic matter. Leeks are heavy feeders that benefit from deeply dug beds with generous compost and aged manure. Prefer neutral to slightly alkaline soil. Add lime to acidic soils.
- pH Range
- 6.5-7.5
- Sunlight
- Full sun (6+ hours). Tolerates partial shade better than most alliums, but stems will be thinner in shade.
- Spacing
- 15cm apart, 40cm between rows
- Watering
- Consistent moisture throughout growth. Water deeply once or twice per week. Leeks are more drought-tolerant than onions but produce thicker stems with consistent water. Reduce watering slightly in win

Harvesting Leek
When ready: Stems are at least 2cm diameter (pencil-thick minimum, but 3-5cm is better). Can be harvested at any size from baby leeks (1cm diameter, 10 weeks) to full-size (5cm+, 5-6 months). No rush - leeks hold well in the ground.
How to harvest: Loosen soil alongside the leek with a garden fork, then lever out. Do not pull straight up - the stem may snap. Trim roots and damaged outer leaves. Wash thoroughly between sheaths (soil and insects hide in the layers).
