Germination
5-10 daysSeeds sprout and first cotyledons (seed leaves) emerge from soil
Keep soil warm (65-75°F) and consistently moist; thin seedlings to proper spacing once they develop first true leaves
Seedling
2-3 weeksTrue leaves develop; plants establish 2-4 sets of leaves
Maintain consistent moisture; begin light feeding with diluted liquid fertilizer; provide bright light to prevent leggy growth
Vegetative Growth
2-3 weeksLeaves multiply and thicken; the characteristic wrinkled, crinkled leaves develop; plant begins forming loose head structure
Water regularly; apply balanced fertilizer every 2 weeks; thin plants to final spacing; monitor for pests
Head Formation
2-3 weeksInner leaves wrap tightly together forming a compact head; leaves become denser and more tightly arranged
Maintain consistent watering; reduce nitrogen to encourage tighter head formation; maintain cool temperatures if possible
Harvest Ready
ongoingHeads reach full size (4-6 inches), leaves are tender, color is vibrant green with slight yellow inner leaves
Monitor daily for maturity; harvest before extreme heat causes bolting; cut at soil level or harvest outer leaves for continued production

Harvest Tips
Harvest when heads reach 4-6 inches in diameter and are firm to touch, typically 45-60 days after planting. Cut heads at soil level with a sharp knife in early morning for maximum crispness. For continuous harvest, remove outer leaves while allowing inner leaves to continue growing. Harvest before temperatures exceed 75°F consistently to avoid bolting. Store unwashed heads in refrigerator crisper drawer for up to 2 weeks.
