How to Grow Carrot in Cold / Highland Australia
When to Plant
October to January only. Very short window. Start early with cloches. Paris Market (round) matures fastest at 60 days.

- pH Range
- 6.0-6.8
- Sunlight
- Full sun (6+ hours). Tolerates light afternoon shade in hot climates, which can actually improve root quality.
- Spacing
- 5cm apart, 25cm between rows
- Watering
- Keep soil evenly moist but not waterlogged. Inconsistent watering causes cracking and splitting. Water deeply 2-3 times per week. Reduce watering slightly in the last 2 weeks before harvest to concent

Harvesting Carrot
When ready: Shoulder of carrot visible at soil surface, typically 2-3cm diameter for standard varieties. Foliage is still green and vigorous. Pull one test root to check size and colour development.
How to harvest: Loosen soil alongside row with garden fork before pulling. Grasp foliage close to crown and pull gently with a twist. In heavy soils, always fork first to avoid snapping roots. Twist off tops immediately after harvest.
