-
Leaf Size and Maturity
Leaf size serves as a primary indicator of harvest readiness. Loose-leaf lettuce varieties can be harvested incrementally, picking individual leaves as they reach a usable size, typically 4-6 inches in length. Butterhead and romaine lettuce are usually harvested as a head when the leaves have formed a dense, compact structure. Observing the overall maturity and firmness of the head guides the determination of harvest time. For instance, a butterhead lettuce with a loosely formed head is likely not yet ready for harvest, while a tightly packed head indicates maturity.
-
Bolting Indicators
The onset of bolting, characterized by a rapidly elongating central stem and the development of flower buds, signifies a critical point beyond which lettuce quality deteriorates rapidly. As bolting progresses, the leaves become increasingly bitter and tough. Monitoring for these visual cues is essential for preventing crop loss. Warm temperatures and long days accelerate bolting, necessitating more frequent observation during these periods. If bolting is detected, harvesting immediately, even if the head is not fully mature, is preferable to losing the entire crop.
-
Time of Day
Harvesting lettuce during the cooler parts of the day, such as early morning, minimizes wilting and preserves leaf crispness. During warmer periods, the leaves lose moisture more rapidly, resulting in a limp texture. Harvesting in the morning, before the leaves have been exposed to direct sunlight and high temperatures, maintains optimal leaf turgor and extends shelf life. If morning harvest is not feasible, ensuring prompt cooling and storage after harvesting at other times of the day is crucial.
