Lettuce are so easy to grow, so nutritious, and so delicious picked fresh from the garden, that everyone should grow them. Grow lettuce in the vegetable garden, tuck it into flowerbeds, or cultivate it in containers. With regular watering, shade from hot sun, and succession planting, you can enjoy home-grown lettuce almost year-round in much of the country. From baby leaf lettuce to big, crisp heads, lettuce is easy to grow in spring and fall, when the soil is cool. Leaf colour and texture vary with variety. All types of lettuce grow best when the soil is kept constantly moist, and outside temperatures range between 45 and 75 degrees Fahrenheit. Before you plant your lettuce seeds, make sure the soil is prepared. It should be loose and drain well so moist without staying soggy. To keep the soil fertile, feed it with organic matter about one week before you seed or transplant. Since the seed is so small, a well-tilled seedbed is essential. Large clods will reduce germination. Direct sowing is recommended as soon as the ground can be worked. Plant seeds Â½ inch deep. Snow wonâ??t hurt them, but a desiccating cold wind will. If you want an earlier crop, however, you may start seeds indoors 4 to 6 weeks before last spring frost date for an earlier crop. Harden off seedlings for about one week, and transplant outside between 2 weeks before and 2 weeks after last spring frost.
