Choosing the Right Lettuce Seeds
Most gardeners grow leaf lettuce because it grows quickly and can be grown from early spring to early summer and again from late summer through late fall. Leaf color can vary from green to red hues. Also common and easy to grow are butterheads. They grow in loose heads and have dark green to buttery yellow leaves with a nice tender flavor. Romaine is somewhat less popular to grow and with a longer days to maturity. Crisphead lettuce requires a long, cool growing season and can be more difficult to grow in some areas of the country.

- Place the tape on loose, well-drained soil.

Lettuce Seed: Getting the Most out of Your Purchase
Lettuce is a cool-season crop that can withstand light frost and can be grown in partial shade. To extend the lettuce season, you can plant a crop every few weeks. During the cooler months, lettuce should be planted in full sun. Because lettuce doesn't like direct afternoon sun during the summer months, many gardeners plant it where taller plants, such as corn, shade it in the afternoon. Many lettuce varieties tend to bolt and get bitter when the hot summer months set in.
When to Plant Lettuce Seeds
Growing lettuce from seed is fairly easy. Lettuce seed can be directly sown into the garden when the ground can be worked in the spring. To get a jump-start on the lettuce season, some gardeners start lettuce seeds indoors and transplant it to the garden in the spring. Gurney's offers a complete line of seed-starting supplies to help gardeners start their lettuce seed indoors. Lettuce seed can also be planted in late summer and into fall.
How to Plant Lettuce Seeds
Lettuce seed should be sown very shallowly, about 1/8 to 1/4- inch deep, in loose, well-drained soil. Water well. Once the seedlings emerge, thin the plants according to the directions on the seed packet.
How to Grow Lettuce Seeds
When the lettuce seedlings emerge, keep the ground moist, but do not overwater.
How to Harvest Lettuce
After the lettuce seeds have grown, the leaf lettuce can be harvested at the baby leaf stage or the mature stage. For a continuous harvest, called cut and come again, cut the plants above the ground, and they will re-grow in a few weeks if watered and given the proper food and fertilizer. Wait until heads form to harvest butterhead, romaine, and crisphead lettuce.
