Seedling
2-3 weeksTiny cotyledons emerge, developing into the first true leaves
Keep soil consistently moist. Thin seedlings to proper spacing once they develop 2-3 true leaves. Provide 12-16 hours of light daily if indoors.
Vegetative Growth
4-6 weeksPlant develops multiple leaves forming a loose rosette; green foliage dominates
Maintain consistent watering and fertilize every 3 weeks with balanced fertilizer. Ensure full sun exposure. Remove any dead or diseased leaves.
Head Formation
3-4 weeksLeaves begin to curl inward, forming a loose, open head structure
Continue consistent watering to prevent tip burn. Support developing heads with stakes if needed in windy areas.
Blanching/Coloration
1-2 weeksOuter leaves begin showing rose-red and cream variegation; inner leaves lighten
Begin blanching 2-3 weeks before harvest by tying outer leaves loosely or covering with shade cloth. Blanching develops the characteristic marbled coloring and reduces bitterness. Harvest after 1-2 weeks of blanching.

Harvest Tips
Harvest in late fall through early winter when heads are firm but tender. Cut the entire head at soil level with a sharp knife, or remove individual outer leaves. Best harvested after the first light frost, which improves flavor. Use within 1-2 weeks of harvest for best quality, though heads can be refrigerated for 2-3 weeks in a plastic bag.
Fun Facts
- 🌱 Variegato di Castelfranco originates from the Veneto region of Italy and is named after the small town of Castelfranco Veneto, where it has been cultivated for centuries.
- 🌱 The beautiful variegation is enhanced by blanching, a traditional technique where outer leaves are loosely tied or covered to exclude light, reducing chlorophyll and developing the characteristic rose-red and cream marbling.
- 🌱 Unlike some radicchio varieties that can be quite bitter, Variegato di Castelfranco is notably mild and sweet, making it one of the most palatable chicories for fresh eating.
