Breso HF1 Cucumber Seeds Packet

Breso HF1 Vilmorin Cucumber Seeds (Reference: 3454343) - This first-generation F1 hybrid variety represents the excellence of Vilmorin's breeding programme, a reference brand in vegetable seeds since 1743. The Breso HF1 stands out for its remarkable earliness and its ability to produce semi-long cucumbers of exceptional flavour quality, completely free of bitterness.

Benefits and uses

This variety is suitable for both beginner gardeners and professional growers looking for a reliable and productive crop. Its earliness allows harvesting from 60 days after sowing, ideal for regions with short seasons or for staggering harvests. The semi-long fruits of 15 to 18 cm are perfect for fresh consumption, composed salads, homemade pickles and culinary preparation.

The complete absence of bitterness makes the Breso HF1 a preferred choice for families with children and all those who appreciate the natural sweetness of the vegetable. Its disease resistance makes it a variety of choice for organic or integrated growing, considerably reducing the need for plant protection treatments.

Technical specifications and innovation

The F1 hybrid status of the Breso guarantees exceptional uniformity of production and superior vigour compared to traditional varieties. This genetic innovation gives the plant enhanced natural resistance to the main fungal diseases of cucumber, including powdery mildew, downy mildew and anthracnose.

Plants develop a robust root system and dense foliage that naturally protects the fruits from direct sunlight. The semi-long shape of the cucumbers, with their regular calibre and smooth, bright green skin, perfectly meets fresh market expectations. The firm and crisp flesh retains its organoleptic qualities for several days after harvest.

This variety presents excellent climatic adaptability and can be grown both in open ground and in a greenhouse or tunnel, depending on regional conditions.

Planting, use and maintenance

Sowing takes place from March to June depending on the region. In a heated nursery, start from March for transplanting in May after the last frosts. For direct sowing, wait until the soil temperature reaches a minimum of 15°C. Place 2-3 seeds per station at a depth of 2 cm, maintaining a spacing of 50 cm between plants and 1 m between rows.

The ideal location combines a sunny exposure (minimum 6 hours per day) and protection from cold winds. The soil should be rich, well-drained and kept moist with an organic mulch. A slightly acidic to neutral pH (6.0 to 7.0) promotes optimal development.

Regular watering at the base, without wetting the foliage, prevents fungal diseases. An application of organic fertiliser every 3 weeks supports continuous production. Training on a trellis or stakes facilitates harvesting and improves air circulation.

Tips, companion planting and expert advice

Companion planting with lettuce is particularly beneficial: the salad provides welcome shade to young cucumber plants while optimising the growing space. Radishes, planted along the border, naturally repel flea beetles. Avoid proximity to aromatic herbs such as mint, which can inhibit growth.

To maximise harvests, pick the fruits regularly while still young: this practice stimulates the production of new flowers. A cucumber left to full maturity considerably slows the formation of new fruits.

In protected growing, maintain a temperature of 20-25°C during the day and 15-18°C at night. Daily ventilation prevents excessive humidity that is favourable to disease. For a staggered harvest, make successive sowings every 3 weeks from March to June.

The seeds can be complemented by our specialist organic fertilisers and natural mulches for 100% ecological and productive growing.
