Growing basics

Lettuce is a cool-season crop, started from seed in the garden or transplanted.

Seeds germinate once soil reaches about 40°F.

Plants bolt or decline once sustained daytime highs reach 80°F.

Varieties in the library run 45 to 75 days to maturity.

Grows in full sun or part sun.

Frost tolerance varies by variety, from frost-tender to frost-hardy.

Space plants 6 to 12 inches apart.
