French Cucumber Seeds

The French Cucumber is the slim, elegant cousin of the everyday cucumber: long and slender with a thin, smooth, deep-green skin that needs no peeling, a mild and gently sweet flavour, and a clean, almost seedless crunch. Its tender bite makes it a favourite for fresh salads, crudités, and chilled summer snacks, where its delicate aroma and crisp texture truly shine — distinctly more refined than the thicker, seedier slicing types.

Planting

This is a warm-season, frost-tender climber, so wait until all danger of frost has passed and the soil has warmed. Direct-sow only once the soil reaches about 16-21 C; seeds will not sprout in cold ground and rot below roughly 10-13 C. Set seeds about 1.3-2.5 cm deep, and expect germination in about 5-10 days at soil temperatures of 18-29 C. After the seedlings emerge, thin in-row plants to roughly 20-46 cm apart, and keep rows well spaced for the vines — about 1.2-1.8 m apart. In Egypt the open-field calendar runs in two main windows: a spring crop direct-sown from about 20 February to 7 April, and a fall crop sown from about 10 to 20 July, while protected plastic-house crops go in from about 1 September to 7 October. In the milder Nile Delta and Lower Egypt, wait for late February-March once the soil at 2-3 cm depth holds near 18-21 C and frost has passed; in warmer Upper Egypt the spring window can open a few weeks earlier. The deep cold of December-January is unsuitable for open-field cucumber and is reserved for greenhouse and tunnel production. You can also start seeds indoors 3-4 weeks before field planting, kept above about 21 C by day and 16 C at night, then transplant about 30 cm apart — handle the root balls gently, as cucumbers dislike root disturbance.

Fertilizing

Feed before planting by working an all-purpose 10-10-10 fertilizer into the soil — about 0.5-1 kg per 9 square metres. As an alternative, a preplant 5-10-10 at about 1.4 kg per 9 square metres works well, followed by a side-dressing of a nitrogen fertilizer about one week after blooming begins and again three weeks later, placed about 15 cm from the base of the plants. Another option is to apply a nitrogen feed per plant once the runners develop, before flowering starts. Go easy on nitrogen, though: too much pushes lush vine and leaf growth, delays flowering and fruit set, and cuts your yield — a steady split program beats one heavy dose.

Care

Give your French Cucumbers full sun for the best growth and fruiting. Keep the watering steady — about 25 mm per week, or 25-50 mm depending on plant size — and remember that moisture matters most during flowering and fruiting; drip lines or soaker hoses keep the foliage dry and help fend off disease. Watch for striped and spotted cucumber beetles (the striped beetle also spreads bacterial wilt), aphids, spider mites in hot dry spells, and pickleworms; floating row covers, pyrethrin, or neem (azadirachtin) help, but lift the covers at flowering so pollinators can reach the blooms. Guard against bacterial wilt, powdery and downy mildew, anthracnose, angular leaf spot, and cucurbit viruses through crop rotation, resistant varieties, and dry foliage. Harvest comes about 50-70 days from planting, with fruit ready roughly 5-7 days after flowering. Pick young, firm, evenly green cucumbers before the seeds harden and the skin yellows, and keep picking every 2-3 days — daily at peak — to keep the vines productive.
