Buttercrunch - Organic Lettuce Seeds

Plant seeds directly in the garden in early spring, starting about 4 weeks before your average last frost date or as soon as the soil can be worked. You can also start seeds indoors 2–4 weeks before transplanting. Optimum soil temperature for seed germination is 55–65°F. Lettuce seed germinates poorly in warm soil and may become dormant as soil temperatures rise above 75–80°F. Resume sowing in late summer for a fall harvest. Lettuce is cold tolerant and will withstand light to moderate frosts. For a steady harvest, make succession sowings every 1–2 weeks during cool weather. Keep plants evenly watered for best flavor and texture.
