Pruning iceberg lettuce — FAQ
When should I prune iceberg lettuce?
Harvest when heads are firm and dense (typically 70–85 days from transplant); remove outer leaves as they yellow throughout growth. Cut the mature head cleanly at the stem base with a sharp knife. If outer leaves are yellowing before harvest, remove them by hand, taking care not to damage the forming heart. Do not attempt to regrow after heading — replant fresh seedlings for succession.
How often does iceberg lettuce need pruning?
Once at harvest; outer leaf removal as needed. Iceberg lettuce is a heading type that is harvested whole rather than pruned. Remove yellowing outer (wrapper) leaves to improve airflow and reduce rot risk. Cut the full head at ground level when the heart feels firm and dense. Iceberg does not suit cut-and-come-again as it forms a tight, solid head.
