5. Fertilization:
   • Incorporate organic matter or a balanced fertilizer into the soil before planting.

6. Weed Control:
   • Keep the growing area free from weeds, which can compete with lettuce for nutrients and water.
7. Pest and Disease Management:
   • Monitor for common pests such as aphids, slugs, and snails. Use insecticidal soap or organic methods for control.
   • Prevent diseases such as damping-off and mildew by practicing good crop rotation and providing adequate air circulation.
8. Thinning and Maintenance:
   • Thin seedlings to ensure proper spacing and encourage healthy growth.
   • Remove any damaged or diseased leaves promptly to prevent the spread of disease.
9. Harvesting:
   • Harvest iceberg lettuce when heads are firm and compact, usually when they reach full size (typically around 60 to 90 days after planting).
   • Cut heads at the base or use a sharp knife to harvest individual leaves as needed.
10. Post-Harvest Handling:

• Immediately after harvest, cool lettuce heads or leaves to preserve freshness.
• Store harvested lettuce in the refrigerator or a cool, shaded area to maintain quality and prolong shelf life.

By following these cultivation practices, growers can cultivate healthy iceberg lettuce plants and enjoy a successful harvest of this popular and versatile vegetable.
