Lettuce can be categorized in several different ways. You will find that we have bibb (butterhead) lettuce, loose-leaf lettuce, crisphead or iceberg lettuce, and romaine lettuce. Plant several different kinds of lettuce for a colorful and tasty harvest. Lettuces can be grown as baby leaf or head lettuce. Baby leaf lettuce is harvested when the lettuce is very young and tender. Head lettuce is allowed to grow and mature until it forms a full head for harvesting. Many lettuces are "cut-and-come-again" lettuces. Meaning, that if you harvest a few inches above the ground, your lettuce will regrow for a second, third, and even fourth harvest! Great for small spaces. Lettuce enjoys cool temperatures and ample moisture. In hot climates, use shade cloth to protect lettuce plants.
