Lettuce Field

Lettuce is considered one of the easier crops to grow. However, it doesn't like to grow when the conditions are too hot or too cold. Lettuce starts as a seed and takes about 60 to 90 days to grow. In the field, seeds of iceberg lettuce are planted side by side in rows.

Seeds of romaine lettuce are also planted in rows in the field. Sometimes the plants are started in a greenhouse and then transplanted out to the field. This only happens during colder months of the year.

Iceberg Lettuce	Lettuce needs a steady supply of water to keep its leaves crispy and tender. As iceberg lettuce grows, it forms a very tight head. That's why iceberg lettuce is sometimes called "head" lettuce.
Romaine Lettuce	The leaves on Romaine lettuce grow straight and open. This allows the sun to penetrate the plants and give them their dark green color.
