Gherkin Krak F1

Gherkin Krak F1 — variety description

Gherkin Krak F1 (Cucumis sativus) is an annual vegetable of the Gourd family (Cucurbitaceae). A mid-early hybrid variety, the gherkins are regularly shaped, intensely green in colour, covered with fine white spines.

For outdoor and greenhouse growing. The variety is disease-resistant.

Used for preserving, pickling and fresh eating. The growing period from emergence to harvest is 45-55 days.

It is recommended to grow gherkins in the same place again after 4 years.

The cucumber is the best-loved summer vegetable for salads and pickling. Gherkins are specially selected for preserving — crisp, with firm flesh and a small seed cavity.

When to sow Gherkin Krak F1

Gherkin Krak F1 seeds are sown in April and May. The crop is harvested in July and August. 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 Gherkin Krak F1

• Sowing method: direct or seedlings
• Depth: 1.5–2 cm
• Spacing: 30–40 cm in the row, 100–120 cm between rows (or on a trellis)
• Germination: 4–8 days at 22–28 °C
• Position: sunny spot

Growing gherkin seedlings takes about three weeks. The optimum temperature during germination is 22°C. Warm, well-drained soils rich in organic matter are suitable for growing gherkins. Gherkins are very susceptible to cold. They can be sown outdoors and in greenhouses. Outdoors in April-May, when the soil has warmed to 10-12 °C. Seeds need 2-3 cm depth, spaced 30-40 cm between plants. Harvest in July-August.

Sow in warm soil, when nights are above 12 °C. Cucumber wants constant moisture — water with warm water without wetting the leaves. Grown on a trellis, it gives more and cleaner fruit.

Harvest and use

Pick often — gherkins at 5–9 cm, salad types at 15–25 cm. Large fruits left on the plant stop new ones from setting.
