How do lettuce seeds grow?
Head lettuce is usually grown from seeds started indoors during warm weather for a fall garden. Transplant head lettuce in rows 12 to 18 inches apart with 10 to 12 inches between each plant. You don’t need lettuce to develop deep roots. In fact, you want to encourage leaf growth over rooting.
How does lettuce reproduce?

Ancient Egyptian artwork, especially tomb paintings, depicts different varieties of lettuce.
How long lettuce seeds grow?
Lettuce seeds grow very quickly. On average, it only takes about 40-50 days for them to reach full maturity. You can start harvesting leafy varieties much sooner than that, since they don’t need to reach full maturity first. However, larger types, or those that produce a head, need longer to mature.
How many lettuce seeds are in a hole?
Lettuce has a high germination rate and planting between 2-3 lettuce seeds per cell or hole would be the best option. Planting 1 seed per hole can be risky in case it doesn’t germinate. Afterward, select the best seedling to use in your garden and nip the others to make sure only a single head will grow in the hole.

Growers often thin the density of growing plants leaving approximately 6 to 12 inches between plants to allow the plants to grow and expand.
Why is it called a head of lettuce?
The term head lettuce describes those varieties on which the leaves grow in a dense rosette. Leaf lettuce describes the varieties with leaves that branch from a single stalk in a loose bunch rather than forming a tight head.
