Tips & Best Practices
- Direct sow lettuce 4–6 weeks before the last frost — it tolerates light frosts.
- Lettuce germinates poorly above 80°F; in summer, start seeds in a cool spot.
- Succession plant every 2 weeks for a continuous harvest.
- Provide afternoon shade in warm climates to delay bolting.
