Seedling
2-3 weeksDelicate feathery foliage emerges; true leaves develop slowly; roots begin expanding slightly below surface
Keep soil consistently moist; provide bright light; thin seedlings once they reach 2 inches tall to 2-3 inches apart to reduce competition
Vegetative Growth
3-4 weeksFerny green foliage develops; orange root begins swelling underground; visible carrots may push slightly above soil surface
Maintain consistent moisture; mulch around plants to retain moisture and prevent root shoulders from turning green from light exposure; remove any large weeds by hand
Root Development
3-4 weeksRoot expands steadily; characteristic half-long shape forms; shoulders become more pronounced; foliage becomes fuller and bushier
Hill soil around roots if they protrude above ground to prevent greening; continue consistent watering; apply 1-2 inches of mulch; monitor for pests
Maturation
1-2 weeksRoots reach full size (6-7 inches long, 1.5-2 inches diameter); color deepens to rich orange; foliage growth slows or plateaus
Reduce watering slightly if desired to concentrate sugars; maintain mulch layer; watch for carrot rust flies; begin harvest testing by gently uncovering shoulder
Harvest
Ongoing from day 70 onwardsRoots are firm, fully colored, and at desired size; foliage remains green but growth has halted; roots can remain in ground in cool weather
Harvest by loosening soil with a fork or hand, then pulling; handle carefully to avoid bruising; remove excess soil; store in cool conditions if desired
