3. Planting Different Types of Lettuce
When you are planting your lettuce seeds or seedlings you will want to sow the seeds into single rows. You can also broadcast the seeds for wider planting rows. If you choose to broadcast you will have to thin out the lettuce for appropriate spacing.
Leaf lettuce should be planted about four inches apart. Any type of cos or loose headed types of lettuce will need to be planted about eight inches apart. A firm headed type of lettuce should be planted roughly sixteen inches apart. The rows of lettuce plants need to be about a foot or just over a foot apart.
Once you have placed the seeds in the ground you will want to cover them with about a quarter of an inch to a half-inch of dirt. Once you have transplanted your seedlings or planted your seeds, make sure that you water the garden bed thoroughly.
