Lettuce Butterhead Justyna

Lettuce Butterhead Justyna — variety description

Lettuce Butterhead Justyna (Lactuca sativa) is an annual vegetable of the Asteraceae family. This is a variety suited to growing in a greenhouse as well as outdoors from spring to autumn.

It produces large green heads that are not only tasty but can also be eaten and stored for a relatively long period of time.

It shows high resistance to disease, especially downy mildew, and withstands adverse weather conditions, keeping high quality for a long time.

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.

When to sow Lettuce Butterhead Justyna

Lettuce Butterhead Justyna seeds are sown in February – September. Harvest takes place from March to November. The months are a guide for a temperate climate — in warmer areas sow 1–2 weeks earlier, in cooler or upland areas, later.

How to sow and grow Lettuce Butterhead Justyna

• 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

To sow the seeds directly, choose a well-drained spot that receives direct sunlight. Whether you plant in the ground or in prepared containers, keep the lettuce seeds moist until they emerge within seven to ten days. 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.
