Why these dates

Lettuce is a cool-season crop. Above 75F it bolts (goes to seed). Plant in early spring and again in late summer for fall harvest. Provide afternoon shade in midsummer to extend the season.

The dates above are anchored to Louisiana's average last spring frost date of 03-15, with offsets standard across university Extension publications. For zone-specific local timing, use the frost date lookup tool with your ZIP code.
