Grow as for carrots, keeping tops of roots covered to avoid cankers. Always use fresh seed.
Sow seed 2 to 3 cm deep, 1 cm apart, into well worked and deeply dug soil that has been well manured for a previous crop. Best sown August to January (cold), August to March (warm) and February to September in the tropics. Seed must be kept constantly moist for germination in around 10 days in warm soil. Thin seedling to 5 to 10 cm apart. Bigger spacings give the largest roots.
