Planting Tips for Organic Heirloom Lettuce Seeds:

Sow directly into very fertile, loose soil.  Thin down to final spacing once plants are established.  For best results, plant in spring or fall.  Harvest outside leaves for a continual harvest.  For longer harvest, stagger plantings every 2-3 weeks.

Heat Tolerance:  If you are growing lettuce in the heat, plant them where they will get afternoon shade.  Lettuce is a spring and fall crop in really hot areas.

Harvest Tips: For a continual harvest, sow a new crop every 2-3 weeks if cutting full heads, otherwise harvesting outside leaves will encourage a longer harvest from individual plants.

Seeding Rate:

30,000 plants/acre, aproximately 2 oz.
