Plant Needs
Sunlight
Full sun to partial shade; requires consistent sunlight to support healthy root development and prevent bolting
Watering
Keep soil evenly moist to avoid woody, bitter roots; avoid overwatering to prevent root rot
Temperature
Thrives in cool temperate conditions; prolonged temperatures above 25°C may trigger premature bolting
Characteristics
- Leaf: Basal rosette of smooth, lanceolate green leaves with slightly serrated margins
- Root: Round, bright scarlet-red taproot with crisp, mild-flavored white flesh

Care Guide
Watering
Keep soil consistently moist; water deeply 2–3 times weekly to support root swelling
Fertilization
Incorporate well-rotted compost into soil at planting time. Use low-nitrogen amendments to prioritize root growth over leaf production
Eggshell powder topdress：Crush dried eggshells into fine powder; sprinkle lightly over soil at planting time to boost calcium levelsPruning
- Thin seedlings to 2–3 cm apart when 2–3 true leaves emerge to allow adequate root growth space
- Remove yellowing outer leaves to improve airflow and reduce disease risk
- Cut back flowering stalks immediately if bolting occurs to redirect energy to root development
