Lettuce Iceberg Queen of Summer

What Lettuce Iceberg Queen of Summer is

Lettuce Iceberg Queen of Summer (Lactuca sativa) is an annual vegetable of the Asteraceae family. This variety comes from Poland and is not suitable for planting too early. Sow the seeds indoors and then plant out the seedlings in the ground from late April to July.

The iceberg lettuce of this variety is light green, very tasty and resistant to downy mildew.

It takes 50-55 days from planting to harvest.

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).

Lettuce and salad are the foundation of the spring table — crisp, fresh and quick. With the right variety and sowing in several batches, you have fresh salad from March to November.

How to sow and grow Lettuce Iceberg Queen of Summer

• Sowing method: direct or seedlings
• Depth: 0.5 cm (the seeds like light)
• Spacing: 25–30 cm
• Germination: 4–8 days at 12–20 °C
• Position: sun to partial shade

Iceberg 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. 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.
