Growth Stages of Romaine Lettuce
Romaine lettuce goes through distinct growth stages that showcase its transformation from seed to harvestable vegetable.
Seedling Stage
During the seedling stage, romaine lettuce starts from tiny seeds. Seeds germinate in soil, typically within 7 to 14 days, depending on temperature and moisture. Young seedlings are small, with delicate, light green leaves emerging. You’ll notice the initial leaf shape is broad and rounded, distinguishing them from mature leaves. Proper watering and sunlight encourage strong growth during this stage.
Mature Stage
In the mature stage, romaine lettuce grows into its recognizable form. The plants reach heights of 12 to 18 inches and develop elongated, sturdy leaves. Leaves have a crisp texture and vibrant green color, with a prominent rib running down the center. As the head forms, it becomes tightly packed and upright. This stage typically occurs 70 to 80 days after planting. Harvesting happens when the leaves are firm and the head feels dense, ensuring optimal freshness and flavor.
