Cucumber Tessa F1

Cucumber Tessa F1: variety and characteristics

Cucumber Tessa F1 (Cucumis sativus) is an annual vegetable of the Gourd family (Cucurbitaceae). The Tesa cucumber is a delicious, fertile hybrid variety recommended mainly for eating fresh in salads.

Produces large cucumbers that grow 18 to 22 cm long. They have smooth, glossy, green skin.

Note the mature size of your cucumber variety, as it can vary on average from 7 to 20 cm.

Harvest them as soon as they reach this mature size. Letting them keep growing will adversely affect flavour and quality.

If even one cucumber is left to grow long enough, the whole plant will stop producing cucumbers.

Check the plants daily for cucumbers ready to pick. Use a knife or scissors to cut the stem, as pulling them off may damage the plant.

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.

How to sow and grow Cucumber Tessa 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

Cucumbers need plenty of light, plenty of water and plenty of fertiliser, as with most vegetables. They thrive in warmth and are suited to growing temperatures between 15-30 °C. They can be grown both outdoors and in greenhouses. Wait until the soil has warmed to about 20 °C before planting your seeds. Choose a spot with plenty of sun and rich, well-drained soil with a slightly acidic to neutral pH. 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. Seeds can also be sown indoors about a month before the last expected frost date in your area in spring. Aim to keep the soil evenly moist and water more in hot weather. Avoid an irregular watering schedule, as this can lead to oddly shaped and bitter cucumbers. Harvest in July-August. Try to keep the leaves dry when watering to prevent fungal diseases.

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.
