Lettuce thrives in cool conditions with consistent moisture. Weed, water and be sure to thin carefully to proper spacing for best quality heavy heads. If birds are attracted to young seedlings, cover with floating row covers or netting. Make a shade structure in hotter climates to extend the growing season.
HARVEST AND USE
Savor young thinnings in your first spring salads. Then harvest plants by cutting mature heads when they feel firm and well-filled out. Be sure to thin properly and keep evenly moist for sweet tasting, full heads. Pull and discard or compost over-mature plants if they begin to elongate (“bolt”) in hot weather as leaves turn bitter at this stage.
