Lettuce can grow from seed to salad in about 1 month in many regions, and only a little longer in others. The key to tender and tasty lettuce is rapid growth, however lettuce has a relatively shallow and compact root system that doesn’t absorb nutrients and moisture from the soil very efficiently, which can slow the growth. So to encourage fast growth, add plenty of finished compost before planting and again as a side-dressing a week or so after seedlings appear or transplants are planted.

Lettuce is a good crop for succession planting. To have a continuous supply of lettuce over the season, make plantings every 10 days to 2 weeks. As the weather warms, grow varieties that tolerate hot weather and resist bolting, such as crisp-head varieties.
Vegetable Garden – Tips on Growing Lettuce From Seed
Give supplemental feedings of compost tea every few weeks until harvest. Gather outer leaves with all except iceburg types, as soon as they are big enough for the salad bowl. The harvest is over when a central stem starts to form. This is the signal that the plant is getting ready to bolt, then the leaves will be bitter.
