Growing from seed

Start Iceberg Lettuce indoors about 4 weeks before your last frost, keeping seeds in cooler soil (around 10–18 °C). Seeds usually come up in around 7 days. Move seedlings out once the danger of frost has passed, in partial sun, spaced about 30 cm apart. Expect to harvest in roughly 85 days.

Iceberg Lettuce seed rarely stays viable beyond 5 years — track what's still worth sowing.
