Crisphead Iceberg Lettuce is cold tolerant and can be planted in soil up to a couple weeks before last frost. However, if your winter weather is extended, seeds may rot or get washed away. Plant in full sun when soil temps are above 60°F for best germination.
Much like the traditional grocery store head of lettuce, crisphead lettuce is a great lettuce to use as a shredded garnish for many dishes.
Allow your Iceberg lettuce to reach full maturity before harvesting the head. Head should be firm when it's harvested, but make sure to get it before outer leaves start to turn brown. If seed stalks start to form, pick lettuce immediately to prevent a bitter crop.
Allow a couple of lettuce plants to bolt and flower. These flowers will dry out on plant and have puffs of white cotton showing around the top (like a dandelion). Pick these flower heads and toss them in a bag.
Break the flower heads apart and oval shaped seeds will fall out. Allow the seeds to dry for a couple of weeks before safely storing them for the next growing season.
