Lettuce Iceberg Great Lakes 118: variety and characteristics

Lettuce Iceberg Great Lakes 118 (Lactuca sativa) is an annual vegetable of the Asteraceae family. It is a popular variety among many farmers because of its large heads with great flavour. Great Lakes 118 adds the perfect crunch to salads and sandwiches.

Early sowing of this vegetable in cool weather is recommended, because the seeds may not germinate in hot weather.

Iceberg lettuce is slightly sweeter. It has a longer growing period (two weeks) than other types.

The young leaves have an excellent flavour, a crunchy and tender texture, and contain protein, sugars, provitamin A, B vitamins, vitamins C, E and K, and minerals (such as calcium and potassium).

How to sow and grow Lettuce Iceberg Great Lakes 118

• Sowing method: direct or seedlings

• Spacing: 25–30 cm
• Germination: 4–8 days at 12–20 °C
• Position: sun to partial shade

Lettuce is hardy and can be planted as soon as the soil is workable. Can be sown directly, 3 seeds in rows 20-30 cm apart. Cover the seeds lightly with about 1 cm of fine soil and firm lightly. Thin to one plant per position, which will ensure a full spacing of 30 cm. Sow every 3 weeks for a continuous supply of fresh lettuce. The seeds germinate even at a soil temperature of 4°C, but poorly above 22°C. In dry weather, keep the soil moist.

Sow shallowly — the seeds germinate better in the light. Above 25 °C germination stops and the plants bolt; in summer, sow in partial shade. Water regularly.

Harvest and use

Harvest whole heads when they are firm, or cut individual leaves in the case of leaf varieties.
