Parsnips are a cool-season root vegetable prized for their sweet, nutty flavour which intensifies after frost exposure. They are slow-growing and demand patience, but reward with excellent yields. A staple of temperate Australian gardens, they struggle in tropical and subtropical climates.

How to Grow Parsnip in Arid / Semi-Arid Australia
When to Plant
Sow March-May (autumn) for winter growth. Harvest July-September. Summer growing is impossible due to heat.
- Soil
- Deep, loose, stone-free loam. Dig to at least 30-40cm depth. Avoid heavy clay or stony soil which causes forked, stunted roots. Do not use fresh manure - this also causes forking.
- pH Range
- 6.0-6.8
- Sunlight
- Full sun to light afternoon shade
- Spacing
- 12cm apart, 40cm between rows
- Watering
- Consistent deep watering throughout the growing season. Inconsistent watering causes cracking and woody cores. Water deeply once or twice per week. Reduce watering slightly as roots approach maturity.
Companion plants: Radish (as row markers), Onion, Garlic, Pea
Avoid planting near: Carrot (shares pests), Celery, Dill

Harvesting Parsnip
When ready: Foliage begins to yellow and die back. Roots should be at least 5cm diameter at the crown. Flavour improves significantly after first frost. Can be left in the ground and harvested as needed.
How to harvest: Loosen soil deeply alongside the root with a fork before lifting. Never pull directly - parsnip roots snap easily. Trim foliage to 2cm. Use immediately or store.
