Description
Lettuce Iceberg is a timeless classic heirloom lettuce that is easy to grow and slow to bolt. It has proven to be one of the most popular crisp heads lettuces for years. Crisp and delicious, it has firm leaves that grow in compact rounded bunches with medium sized heads. It has light green ruffled outer leaves with white hearts.
Lettuce does best in full sun, however, if you live in a hot climate then some shade will benefit your lettuce. Start lettuce seeds indoors or out, by sprinkling seeds in rows or in containers, and covering with a layer of soil. Seedlings should appear within a week to 10 days. Lettuces can tolerate cold, but care should be taken to protect them from wind.
Lettuce and other leafy greens have high water transpiration rates and should be kept consistently moist and in well drained soil. If leaves begin to wilt, plants need more water. Harvest your lettuce when it is full size and the center is firm.
