The leaves become bitter and the plants begin to bolt as the stem elongates into a tall bloom stalk. Leaf lettuce varieties take about 40 days from seeding to harvest while head types may take 70 days. This is another reason the head types are more of a challenge. To get more from your garden space, consider interplanting your lettuce with slower maturing crops.
Pick outside leaves first; the plant will continue to actively grow and produce. Or cut the entire plant 2 inches above the base. The new plants may not have the lovely form of the original, but more leaves will be produced. To store lettuce, soak it immediately in an ice water bath for five minutes. Then drain, and store in zip-top plastic bags in the refrigerator.
