Parsnips are a classic winter root, sweetened by frosts and perfect for roasts.
When to Sow
- Direct sow Feb–May outdoors or under cover for earlier germination.
- Fresh seed is essential, as old seed loses viability quickly.
How to Grow
- Sow thinly in rows 30cm apart.
- Thin seedlings to 10cm spacing.
- Keep soil moist for even germination.
Harvesting
- Harvest Oct–Feb.
- Roots improve in flavour after frost.
Polytunnel Growing Tips

- Tunnel-grown parsnips mature sooner.
Quick Tips Recap
- Sow: Feb–May
- Spacing: 10cm
- Harvest: Oct–Feb
- Polytunnel advantage: Better germination, earlier cropping
