Seedling
10-14 daysTiny cotyledons emerge and first true leaves appear. Plants are delicate with thin stems.
Keep soil moist. Provide consistent light if starting indoors. Thin seedlings to proper spacing once they have 2-3 true leaves.
Vegetative Growth
20-30 daysLeaves expand and rosette structure begins to form. Plant develops multiple leaves but has not yet headed up.
Maintain consistent moisture and cool temperatures (60-70°F ideal). Apply balanced fertilizer every 2-3 weeks. Mulch around plants to retain moisture and keep roots cool.
Head Formation
15-25 daysLeaves begin to curve inward, forming the distinctive elongated head. Outer leaves deepen in red color.
Continue regular watering. Reduce nitrogen slightly to encourage heading. Cooler temperatures favor tighter, more colorful heads.
Maturity
3-7 days at peak qualityFully formed elongated head with deep red outer leaves and lighter center. Heart is crisp and tender.
Monitor for bolting (especially in heat). Check for pest damage. Heads are ready for harvest when firm and well-colored.
Harvest
Harvest window is 3-10 days for best qualityHead is fully mature, firm, and colorful. Leaves are crisp and bitter flavors are minimal.
Harvest in early morning when plants are fully hydrated for best crispness. Cut at soil level or pull entire plant.

Harvest Tips
Harvest when heads are firm and well-colored, typically 50-70 days from planting. For best crispness, harvest in early morning when plants are fully hydrated. Cut the entire head at the soil line with a sharp knife, or pull the whole plant. Outer leaves can be harvested individually while the plant matures for a longer harvest period. Romana Rosso is best eaten fresh within a few days of harvest, though it stores for 1-2 weeks in the refrigerator's crisper drawer.
Fun Facts
