Iceberg Lettuce Care

Iceberg lettuce doesn't set deep roots, so it requires proper irrigation to keep the root zone moist. Watering the bed when the top inch of soil feels dry is usually sufficient. Depending on how cool and moist the weather is, the lettuce may require watering every five to 10 days.

Feed lettuce plants every two weeks with a balanced water soluble or granular fertilizer, such as a 10-10-10 or a 5-5-5, diluted to half strength.

If you don't have enough light on a windowsill, grow your crop under lights.
