HOW TO GROW LETTUCE
Start indoors 4-5 weeks before last frost, plant out 4 weeks before frost. For fall harvest, transplant 8–10 weeks before first frost. Direct seed after last frost 1” apart, thin. Plant every 2–3 weeks to ensure continuous crop. Avoid sowing one long row all at once. Choose bolt-resistant varieties for summer harvest. Lettuce seed can enter thermal dormancy at high temperatures, see optimum germination temps. For continuous winter cold frame harvest from Elliot Coleman’s book ‘The New Organic Grower’: September 1 to 10, sow every 3-1/2 days. September 10 to 18, every 2 days, September 18 to October 10, every 3-1/2 days, October 10 to November 15, every 7 days. November 15 to December 15, every 10 days. Soil pH 6.0-6.8. Hardiness zones 6-9. Annual.
