Seed germination
2-3 weeksSeeds are very small and slow to germinate. Soil appears unchanged except for emerging fine cotyledons.
Keep soil moist; germination takes 14-21 days. Thin seedlings to proper spacing once they develop first true leaves.
Seedling and thinning
1-2 weeks after emergenceTiny seedlings with feathery foliage emerge; plants are delicate and easily crowded.
Thin to 3-4 inch spacing when seedlings are 2 inches tall. Remove competing seedlings carefully to avoid disturbing remaining plants.
Vegetative growth
3-4 weeksFeathery green foliage develops rapidly; roots are beginning to expand underground but remain thin.
Maintain consistent moisture and weed carefully. Remove any competing weeds that might restrict root development.
Root development
3-4 weeksFoliage becomes bushier; underground the characteristic round root begins forming and swelling.
Ensure soil remains loose and well-draining; compact soil causes deformed, forked roots. Consistent watering is critical.

Harvest Tips
Rondo carrots are ready to harvest 65-75 days after planting when roots are 1-1.5 inches in diameter. Pull gently from the soil or use a small fork to loosen soil first. Harvest in early morning for best texture and sweetness. Can be harvested smaller for baby carrots or left in ground in cool weather (they'll keep in soil up to 30 days in autumn). Remove green tops before storage to prevent moisture loss.
