Harvest Tips
Harvest baby leaves at 4-5 weeks for tender microgreens, or wait 7-8 weeks for full mature heads. Cut outer leaves continuously for extended harvest, or cut entire head at soil level when desired size is reached. Morning harvest ensures crispest leaves. Store in refrigerator in plastic bags for up to 2 weeks.
Fun Facts
- 🌱 Red leaf lettuce's crimson color comes from anthocyanin pigments, the same compounds that make blueberries and red wine beneficial for health. The red coloration intensifies with cooler temperatures and more sunlight exposure.
- 🌱 Lettuce has been cultivated for over 2,500 years, with evidence of its use in ancient Egypt where it was associated with fertility and rebirth in religious contexts.
- 🌱 Red Head and other loose-leaf lettuces can be continuously harvested by picking outer leaves, allowing the plant to regenerate and produce more leaves for weeks or even months under ideal conditions.
