All Year Round Lettuce (53 Days)
The All Year Round Lettuce is very popular in England and Australia. As the name implies it can be sown at any time – spring to fall and will be slow to bolt. The crisp, tight hearts are an appealing light green with the centers appearing a bit blanched.
Germination: 4-10 days
Germination Temperature: Optimum soil temperatures are 60-75ºF. Soil above 75ºF. inhibits germination.

Outside Sowing: Spring when the soil temperature reaches at least 50ºF. Sow 1” apart, thin to 6-12”, depending on the size of lettuce you want, baby to full heads. Keep soil moist during germination.

Starting Indoors: 3-4 weeks before planting outside. Sow 2-3 seeds per cell/pot, thinning to one per cell/pot. Provide 60-70 ºF. soil temperatures. Transplant out, 8-12” apart in rows 12” apart.
