How to grow Radishes, step by step
Sow direct, often
- Direct-sow every 1–2 weeks in cool weather; thin to 2 in.
- They dislike transplanting.
Keep growing fast
- Steady water grows crisp, mild roots; drought makes them hot.
- Thin early so roots can size up.
Pull promptly
- Harvest as soon as roots reach size — they go woody fast.
- Pull before warm weather makes them bolt.
