Sow Harvest
The method
- 1
Sow direct
Scatter thinly 1 cm deep. Sow a short row every 10 days.
- 2
Water often
Dry soil = hot, woody roots. Water little and often.
- 3
Pull promptly
Harvest as soon as roots swell — a week too late and they're inedible.
Common problems
Hot, woody roots
Water more and harvest earlier.
All leaf, no root
Soil too rich in nitrogen. Sow in leaner soil.

Field tips
- “Sow between slow rows of carrots to mark them and use the space.”
- “Try winter varieties like daikon for autumn sowings.”
