- Lettuce is hardy and can be planted as soon as the soil can be worked. Can be direct seeded, 3 seeds every 8 inches in rows 8-12 inches apart, as early as the soil can be worked or grown indoors 3-4 weeks before transplanting outdoors.
- Cover seed lightly with about 1/8 inch of fine soil, and firm soil gently.
- Thin young seedlings to one plant per spot.
- Sow every 3 weeks for a continuous supply of fresh lettuce.
- Seeds germinate even at low 40-degree F soil temperature, but poorly above 75-85-degree F.
