Growth Stages

1

Seedling

1-2 weeks

Tiny leaves emerge within 3-5 days; true leaves develop within 1 week

Thin seedlings to 2-3 inch spacing when first true leaves appear. Overcrowding causes small, forked roots.

2

Vegetative Growth

1-2 weeks

Feathery, deeply lobed green leaves develop; root begins expanding underground

Keep soil consistently moist. Provide steady nitrogen for leaf development. Monitor for flea beetles.

3

Root Development

1-2 weeks

Long, slender white root emerges and elongates; roots may protrude slightly above soil surface

Hill soil around protruding roots to prevent green shoulders. Maintain even watering to prevent splitting.

4

Maturity

2-3 days optimal

Roots reach 6-10 inches long with crisp, tender white flesh; leaves mature and darken

Begin harvesting when roots are young and tender for best flavor. Delay harvesting too long risks bitterness and woodiness.
