Growth Stages

1

Germination

7-10 days

Seeds sprout and first true leaves emerge; seedlings are delicate and pale green

Keep soil consistently moist; maintain temperature between 60-70°F; provide light once sprouted; thin seedlings to proper spacing

2

Seedling & Early Growth

2-3 weeks

Young plants develop 3-4 true leaves and establish root system; leaves are thin and tender

Maintain consistent watering; fertilize lightly with diluted balanced fertilizer; protect from pests; ensure adequate light to prevent leggy growth

3

Vegetative Growth

3-4 weeks

Plant produces more foliage, outer leaves expand, and head formation begins; leaves are crisp and medium-sized

Continue consistent watering; maintain cool temperatures (60-70°F ideal); side-dress with nitrogen-rich fertilizer halfway through stage; monitor for bolting if temperatures rise

4

Head Formation

2-3 weeks

Outer leaves tighten around developing head; interior leaves blanch to pale green/white; head becomes denser and more compact

Maintain steady water supply to prevent tip burn; reduce nitrogen fertilizer; provide afternoon shade in hot weather; harvest when heads feel firm

5

Harvest Ready

At harvest maturity

Head is fully formed, compact, and dense; outer leaves are medium green; interior is crisp and pale; head feels solid when squeezed gently

Harvest in early morning when plants are most crisp; cut at soil level or pull entire plant; use sharp knife for clean cut; refrigerate immediately

Fun Facts

  • 🌱 Iceberg lettuce is called 'iceberg' because it was originally packed in ice for cross-country shipping in the early 1900s, and the name stuck despite modern refrigeration making it unnecessary.
  • 🌱 Salinas, California produces nearly 70% of the nation's lettuce, and the 'Salinas' variety name honors this agricultural region's reputation for premium lettuce cultivation.
  • 🌱 Lettuce is one of the few vegetables that doesn't continue to ripen after harvest, so proper timing is critical—unlike tomatoes, you can't wait for it to mature once picked.
