Garden lettuce is a fast-growing cool-season annual best planted in spring or autumn when temperatures stay between 45–75°F (7–24°C). Keep the soil evenly moist and provide at least 4–6 hours of sunlight daily for full, tender leaves. Harvest outer leaves regularly to extend the productive season and prevent early bolting.
