Seedling
2-3 weeksTiny cotyledons emerge within 5-10 days; first true leaves appear shortly after
Keep soil consistently moist but not soggy. Provide bright light. Thin seedlings to proper spacing once true leaves develop
Vegetative Growth
3-4 weeksPlant develops multiple rosette leaves; foliage becomes increasingly frilled and elongated. Plant grows outward rather than upward
Maintain consistent watering and moderate fertilizer every 2-3 weeks. Mulch around plants to retain moisture and regulate soil temperature
Leaf Development
2-3 weeksLeaves reach full length and texture; plant becomes fuller with deeply serrated, attractive foliage
Begin selective harvesting of outer leaves. Continue regular watering and monitor for heat stress in warm seasons
Harvesting Ready
1-2 weeksPlant reaches mature size with full rosette of tender, flavorful leaves ready for cutting
Harvest outer leaves regularly to encourage continued production and prevent bolting. Keep soil consistently moist
Bolting/Decline
Variable, accelerates in heatPlant sends up central flower stalk; leaves become bitter and tough as plants mature toward seed production
Harvest immediately or remove plants. In hot weather, provide afternoon shade to extend harvest window

Harvest Tips
Begin harvesting outer leaves when plant is 4-6 inches tall, allowing inner leaves to continue growing. Use the 'cut and come again' method: harvest leaves from the outside, leaving at least 1-2 inches of the crown to regrow. Alternatively, harvest entire plant when mature. Best harvested in early morning when leaves are crisp. Most tender when harvested before temperatures exceed 75°F; quality declines rapidly in heat
Fun Facts
- 🌱 Long Leaf Lettuce varieties are particularly well-suited to coastal climates because the marine influence moderates temperature extremes and reduces bolting risk compared to inland regions
- 🌱 Lettuce is approximately 95% water, making it extremely low in calories while still providing important vitamins and minerals
- 🌱 The 'cut and come again' harvesting method can extend a single planting's productivity by 4-6 weeks compared to full plant harvest methods
