Out of the two varieties of lettuce I grew this year I much preferred this Outredgeous variety. It grew so strong and healthy compared to my other lettuce and even came back after being severely damaged by slugs/other pests at the start of it's season. I will definitely be growing this lettuce regularly from now on.
This one out does all the reds. Outredgeous is so red that botany students didn't recognize it as lettuce when they saw it in Frank Morton's breeding nursery. A superb upright baby leaf variety that forms a loose head at maturity. Makes an outrage of red in your premium gourmet salad mix.
Leaf lettuce may also be grown at a lower density, allowing more space between the plants. The plants will get larger and the leaves will get bigger. Plants may be cut to the ground as above, or you can just remove the largest leaves as you need them. When thinning out a planting of lettuce, you can move some of the plants around the garden, filling in any empty spots. Done at dusk or on a rainy day, these small transplants will take quickly to a new location.
Lettuce is generally considered a cool-weather crop, but varieties will do quite well in the heat of summer. Look for types that are especially tolerant of warm weather. In midsummer, lettuce may be grown in the shade of tomatoes or pole beans. You can also grow it under a section of shade cloth, stretched over hoops. The key to having a good supply of high-quality lettuce, is to plant a few seeds every two or three weeks during the growing season. Keep your eyes open for any vacant spots in the garden and when you find one, tuck in a few lettuce seeds. Once a lettuce plant goes past its prime, the sap becomes milky, the leaves get biter and the center of the plant will elongate into a seed stalk. Don't let these over-mature plants take up space in your garden. Pull them out quickly and replant the area with new lettuce seed or a fall crop of beets or carrots.
Lettuce can be started indoors under lights (where it's easy to monitor growth), or you can plant seeds directly in the garden. Sprinkle the seeds as sparsely as possible over the prepared area and press them down gently with the palm of your hand. Cover with a very fine layer of soil as light is required for good germination.
