Common Name(s): Lettuce
Categories: Fruits and Vegetables
Lettuce is one of the most important year-round salad vegetables. It is not difficult to grow lettuce successfully provided you keep in mind that all types need well-prepared soil that is rich in organic material, regular thorough watering and feeding every two weeks. There are four types of lettuce: iceberg or crisphead, butterhead, loose-leaf, and cos or romaine. The most commonly grown is the iceberg type. Loose-leaf types can remain in the garden for about three months before replanting. Planting the correct hybrid for the time of year is most important.
