Seedling
2-3 weeksTiny cotyledons emerge with characteristic oval shape; first true leaves appear with slight venation patterns
Keep soil consistently moist but not soggy. Maintain warm soil (65-75°F) for germination. Thin seedlings to prevent damping off.
Vegetative Growth
4-6 weeksRosette expands with 4-8 leaves; variegation begins to show with green and light purple patterns; plant remains relatively compact
Provide consistent moisture and full sun. Begin light fertilizing with balanced fertilizer every 3-4 weeks. Remove any damaged outer leaves.
Leaf Development & Variegation
3-4 weeksCharacteristic pale green base leaves with burgundy variegation become more pronounced; leaves develop ruffled edges typical of variety
Maintain even moisture to prevent stress-induced bitterness. Apply mulch around plants to regulate soil temperature and moisture. Avoid overhead watering to prevent leaf spots.
Maturation
2-3 weeksFull rosette formed with 12-16 leaves; distinctive two-toned coloring fully developed; leaves reach 6-8 inches long
Monitor for bolting triggers (temperature extremes). Begin light harvesting of outer leaves if desired. Maintain consistent watering.
Harvest-Ready
Extends 1-2 weeks before possible boltingRosette fully mature with vibrant variegation; leaves tender and mild-flavored; plant reaches 8-10 inches diameter
Harvest in morning when leaves are crisp. For whole rosette harvest, cut at soil line. For leaf-by-leaf harvesting, remove outer leaves first.

Harvest Tips
Cicoria di Castellfranco is best harvested when the rosette is fully mature but before bolting (typically 70-100 days). Harvest in the morning when leaves are crisp. For whole rosette harvest, cut at soil line with a sharp knife. Alternatively, harvest individual outer leaves continuously to extend the growing period. The plant can be stored in a cool, humid environment (32-40°F, 95% humidity) for 2-3 weeks.
Fun Facts
- 🌱 Cicoria di Castellfranco is an ancient Italian heirloom from the Veneto region near the small town of Castelnuovo, prized since the 1600s and protected as a PAT (Traditional Agro-Food Product) in Italy.
- 🌱 The distinctive variegation develops best in cooler weather (55-65°F nights); warm conditions may produce more green coloring and less of the signature burgundy patterning.
- 🌱 Unlike traditional heading radicchio varieties, Cicoria di Castellfranco forms loose, open rosettes rather than tight heads, making it easier to harvest leaves continuously throughout the season.
