The number-one Polish pickling cucumber. Borus F1 is a mid-early, very high-yielding field cucumber variety developed specifically for pickling. The fruits are slender and elongated, with green skin featuring distinct stripes and large warts, and, above all, have a small seed cavity – thanks to this, they remain firm and crunchy after pickling, without a hollow centre. The plants are resistant to scab and tolerant of downy mildew.

What makes this variety stand out
For years, Borus F1 has been the most frequently chosen Polish pickling cucumber, both by allotment gardeners and by growers supplying cucumbers to pickling facilities. The plants produce almost exclusively female flowers, 1–3 per node, so the yield is abundant and concentrated. The fruits are more slender than typical cucumbers for preserving, with dark green skin, light stripes and white warts, and retain an exceptionally vivid green colour after pickling.
Its good health adds to its appeal: resistance to scab and high tolerance of downy mildew allow Borus to keep fruiting until September, when less resistant varieties have already withered. This is a variety that can be recommended for making your first homemade pickles without much risk.
Growing step by step
Sowing (May, directly outdoors): once the soil has warmed to 12–15°C, sow in rows 80–100 cm apart, individually or in groups of 2–3 seeds every 15 cm, at a depth of 2–3 cm. Germination takes 7–14 days. For an earlier harvest, you can raise seedlings in pots and plant them out after 15 May.
Thinning and protection: in groups, leave 1–2 of the strongest plants. Until flowering, cover the bed with fleece or perforated film for faster growth and protection from cold weather and flea beetles.
Position: soil heavily enriched with compost or manure, warm, well-drained and moisture-retentive. Mulching with straw is worthwhile: the fruits rest on dry bedding and stay clean, while the soil does not dry out.
Care: water evenly with warm water at the base of the plant, in the morning; feed every 2 weeks. Harvest every 2 days – at 8–12 cm for pickling, and earlier for gherkins. Regular harvesting keeps the plants producing fruit for many weeks.
Uses
Borus F1 is a cucumber for pickling – both for quick pickles eaten after a few days and for winter fermented pickles in a crock or jars. The fruits are also suitable for preserving and making gherkins, while young fruits can be eaten raw. For anyone planning larger supplies, it is the safest choice: plenty of uniform fruit in a short time.
Gardener's tip
For pickling, harvest the fruits in the morning, when they are at their firmest, and pickle them the same day – a cucumber that has been left for a day loses its crunch in the jar. A horseradish, oak or blackcurrant leaf added to the brine provides tannins that help keep the pickles firm.
