Start indoors 4-6 weeks before last frost, plant out 3–6 weeks before frost. For fall harvest, transplant 8 weeks before first frost, without additional protection. In a hoophouse, you can plant 2-3 weeks later. Leaves become sweeter during winter greenhouse growing. Direct sow 1–2 weeks after soil can be worked above 55˚F. Late fall varieties sow in September for baby leaf, sow in 2-4” wide band, 1” apart, sow every 2 weeks for a continuous harvest. Control weeds early to help slow growing seedlings. Triple rinse harvest, remove broken leaves, store at 32˚F for 10-14 days. Soil pH 6.5-7.5. Hardiness zones 5-9. Annual.
