All lettuces need loose, well drained soil. Sow in open ground; barely cover seeds. Loose-leaf lettuce can be grown as close as 4 in. apart; thin all other types to 1 ft. apart. Grow mesclun in blocks 4 in. wide and don't thin. For prolonged harvest, sow at 2-week intervals. In cold-winter regions, begin sowing seed for all types after frost, as soon as soil is workable; where summers are very short, sow indoors, then transplant seedlings outdoors after last frost.
In light of fall’s arrival, I’m going to start planting again! First, I have to make sure the soil is ready. I typically do this by breaking up the ground with my hands and gardening tools, adding some good soil.
