How to sow?
Iceberg lettuce will thrive in the cool spring season and its best to prepare a well-drained soil bed which receives about 4 to 5 hours of sunlight every day. Iceberg lettuce doesn’t develop deep roots so remember to keep the base of the plant properly moist. If you plan to plant lettuce in a rather warmer zone, protect the plant from direct afternoon sun. Excessive warmth may lead the lettuce plant to bolt and cause a very bitter taste in the leaves.
