Lettuce - Iceberg Superior - Lactuca sativa
Hardy annual Iceberg produces compact, large heads with crisp hearts, and light green leaves. With unrivaled crunch, this lettuce is one of America's favorite vegetables. Iceberg is heat resistant, but also does well in cool temperatures. Superior is tipburn resistant.
Soil & Water: Lettuce likes full sun except in hot summer climates where it prefers some shade, especially in the afternoon. Add plenty of compost to the soil to encourage rapid growth. Water evenly and moderately to prevent bitterness.
Planting & Growing: Start seeds indoors 4 weeks before transplanting outside, or sow seed directly as soon as the soil is workable. Make successive plantings every 10-14 days for a continuous harvest. In mild climates, lettuce can be sown from spring through fall.
Harvesting & Storage: Harvest the entire plant when mature, but still young and crisp. All lettuces are at their best when picked as needed and used immediately. Head lettuce will only last a few days in the refrigerator before deteriorating.
