Germination & Seedling
10-14 daysTiny cotyledons emerge 5-10 days after sowing. First true leaves appear pale green and delicate.
Keep soil evenly moist. Provide bright light to prevent leggy growth. Thin seedlings to proper spacing once 2-3 true leaves appear.
Vegetative Growth
20-30 daysPlant develops multiple layers of deeply crinkled outer leaves that are bright green. The rosette expands outward. Inner leaves begin to pale in color.
Water consistently. Ensure adequate spacing for air circulation. Mulch around base to retain moisture and keep soil cool. Monitor for pests.
Heart Development
10-15 daysInner leaves become noticeably pale yellow-green, forming a distinct tender heart. The plant reaches near-mature size with full frilly texture.
Continue consistent watering. Reduce nitrogen fertilization to prevent bolting. Cool temperatures favor continued quality leaf production.
Maturity & Harvest-Ready
Variable with harvesting methodFully developed rosette with vibrant green crinkled outer leaves and creamy pale yellow-green heart. Leaves are tender and flavorful.
Begin harvesting outer leaves or harvest entire head. Can continue harvesting outer leaves for extended production if plant remains cool and well-watered.
Bolting (If Not Harvested)
Accelerates in warm temperatures above 70°FPlant elongates and sends up a central flower stalk. Leaves become bitter and lose tenderness.
Harvest immediately if bolting begins. Plant in spring/fall or provide shade in summer to prevent bolting. Remove bolting plants that cannot be salvaged.

Harvest Tips
Begin harvesting outer leaves once they reach full size (about 45-60 days from sowing). Pinch or cut outer leaves individually for continuous harvest, leaving the inner rosette to continue growing. Alternatively, harvest the entire head by cutting just above soil level. Early morning harvest ensures crispest leaves. Cut-and-come-again method extends harvest window by 2-3 weeks. Cool seasons produce superior flavor and texture compared to warm-weather harvests.
