Crisphead lettuce can be grown anywhere as long as you have composted soil. Lettuce
grows best if planted indoors and transplanted outdoors in early spring.
Lettuce does well in composted soil. It does not do well in clay soil. Make
successive plantings. Plant
your seeds indoors 3 to 6 weeks before setting outside. Lettuce will better
tolerate heat if plants are well thinned and air can circulate around them.
Spring planting should occur as soon as soil can be worked, and fall planting
done around June or July. Plants grow 2 - 10" tall.
