Cucumber Jazzer F1 seeds - Cucumis sativus

Cucumber Jazzer F1 is a high-performing hybrid, selected for its productivity and consistency. This variety produces straight, smooth or very slightly thorny fruits, approximately 20-22 cm in length, of a uniform dark green colour. Its flesh is crisp, juicy and without bitterness, perfect for raw consumption: salads, sandwiches, crudités.

This variety exhibits strong resistance to the main cucumber pathogens, which are Cca and Ccu, and an intermediate resistance to viruses such as CMV and to powdery mildew (Px), depending on conditions.
Jazzer F1 is also tolerant to temperature variations and environmental stresses. It is suited to cultivation under glass (tunnel) or in open ground.

The designation F1 means that the Jazzer cucumber is a first-generation hybrid. This means it is the result of the cross-breeding of two cucumber lines selected for their complementary qualities (disease resistance, regularity of production, flavour, vigour). F1 hybrids do not reproduce true to type from one generation to the next, so it is advisable to purchase new seeds each year.

Sow from March to June, in pots under cover or directly in open ground when the soil has warmed. The harvest occurs 2 to 3 months later, from July until the first autumn chills. For small gardens, training on netting or wire mesh is recommended: it saves space, improves leaf aeration and makes picking easier.

Like the tomato, the cucumber is one of the emblematic summer vegetables. Refreshing, light and low in calories, it can be enjoyed in salads, as crudités or simply seasoned with a dash of lemon and aromatic herbs. We distinguish between long and smooth varieties, like Jazzer F1, and short or half-long cucumbers, thorny or smooth, as well as more original varieties like the snake cucumber or the horned melon, which need more heat.

An easy vegetable to grow: the cucumber appreciates light soils, rich in humus, well-drained and kept moist. A warm, sunny exposure promotes its development, with ideal temperatures between 18 and 22 °C. Greedy for water, it must be watered regularly, preferably at the base to avoid wetting the foliage.

Harvesting Jazzer F1 cucumbers: Harvest as soon as the fruits have reached their final size, before they turn yellow. Picked young, they are more flavoursome and regular harvesting stimulates the formation of new fruits. They keep for a few days in the refrigerator, but can also be prepared in jars, as pickles or through lacto-fermentation to prolong the pleasures of summer.

A little gardener's tip: like all cucurbits, the cucumber can be susceptible to powdery mildew, which appears as a white felting on the leaves. To limit this risk, avoid watering the foliage, ensure good ventilation under cover and remove affected leaves. A spray of horsetail decoction or wettable sulphur can also strengthen the plants' resistance.

Its companions in the vegetable garden: associate your cucumbers with lettuces and beans, and you will promote their growth and balance in the garden. Conversely, avoid planting them too close to potatoes or tomatoes, with which competition is unfavourable.
