To define a number range, you have to create a new number interval: 1  Specify an alphanumeric key with up to 2 characters. 2  Specify the limits of the number interval.  Mark the number range if it is planned for external number assignment.
Inspect the lettuce plants for leaves that are ready to harvest. Most leaves are mature enough once they reach 1 to 3 inches long, but they should still be tender up to 6 inches long. Cut off the outer leaves of the plants with a small pair of garden shears to harvest just a few leaves.
1 To defrost your lettuce leaves, remove them from the bags and place them flat on a piece of paper towel or a dish towel at room temperature for about an hour. 2  You can place a baking sheet under the towel to protect your work surface from moisture, if you wish.
