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 Warm Temperate Australia
When to Plant
Sow March-August. Best results from April-June sowings (root development through cool winter). Harvest July-November.
- 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
Warm Temperate Growing Tips for Parsnip
Recommended Varieties
- Hollow Crown
- Melbourne Whiteskin
- Guernsey (canker resistant)
- Javelin
Key Challenges
- Slow germination in cool soil
- Canker in wet winters
- Forked roots in heavy soil
Pro Tips
- Prepare beds deeply - at least 30cm of loose, stone-free soil
- Sow with radish as row markers (radish germinates in days, parsnip in weeks)
- Keep soil consistently moist during the long germination period
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.
