Cucumber 'F1 Iznik'

Cucumber 'F1 Iznik' is a terrific and very popular European cocktail cucumber that’s seedless, spineless, thin-skinned, smooth, dark green, crisp and perfect for fresh snacking.
F1 Iznik is a parthenocarpic variety, producing fruit without the need for pollination. The compact, plants are very abundant producers of small to medium-sized cucumbers, 12 to 14cm in length.

Iznik is a great variety for container and greenhouse production as well as open-field. The compact growth makes it perfect for growing in large pots, preferably in greenhouses or warm outdoor areas. This variety is resistant to mildew and does not need pollinating. 60 days to maturity.
The fruit is mild, nicely sweet, with a bit of a melon overtone. This fine multi-purpose cucumber is suitable for snacking, salad, or pickling. Iznik F1 is a delicious and crispy mini cucumbers with smooth skin, making it ideal to enjoy raw.

Sowing: Sow indoors February to April or outdoors from mid May to June.
Cucumber seeds should be sown in a propagator between March and April. But you can get started in February if your greenhouse is heated, and in May to June if you plan to sow the seeds directly outdoors.
The seeds can be started off early indoors and grown in 7.5cm (3in) pots. Place two or three seeds, on their sides, about 2.5cm (1in) deep per pot, which is filled with moist compost. Sometimes cucumbers transplant badly, handle with care and disturb the roots as little as possible.
Cucumbers can be sown in situ from late May when all risk of frost has passed and the soil temperature is at least 16C (61F). Prepare holes 30cm (12in) wide and mix in plenty of well rotted compost or manure. Mound the planting hole up slightly as this will help with the plants' drainage. Sow two seeds per mound placing them on their sides, about 2.5cm (1in) deep.
Cucumbers are warm season crops, with no tolerance to frost. They must have temperatures of between 18°C to 27°C (64-81°F). In cold areas protect the young plant with mulches or cloches. A thick mulch will also help retain water.
After they have germinated thin out the seedlings to remove the weakest. Seeds germinate best if kept at 20*C (68*F). Ideal night temperature should be no lower than 16C (60F). This temperature should be maintained for four to six weeks after the seedlings have been planted out, so harden off and plant out when all frost has passed.

Cultivation:
Nip out the growing point when the plants have about five leaves to encourage a stronger growth. Train up the supports tying in as required. When the plant has reached the top of the support, nip out the tip, two leaves beyond the last flower. Side shoots will then develop, producing more flower and fruit.
If allowed to trail on the ground nip out the main shoot when it has produced about 1.5m (54in) of growth and remove side shoots after one leaf.
The best forms are the all female ones. All female types may produce male flowers if they are grown under stressful conditions. These flowers should be removed. If grown in a greenhouse, keep it damped down to reduce any pests. Water regularly and feed with a high potash liquid feed every two weeks.
Keep an eye out for slugs and snails especially when the plants are young. If they become a problem, use a recommended proprietary brand of slug and snail bait. Try to avoid watering from above as this may lead to a fungal problem especially in warm weather. Pick off any badly affected leaves and spray with are commended proprietary brand of fungicide.

Pollination:
Flower and therefore fruit development is sometimes a little erratic at the start of the season. Generally the first flush of flowers will be mainly female. Female flowers have a small swelling (embryonic fruit) behind the petals. Most pollination is done by insects, but if fruit is failing to set, them the female flowers can pollinated by hand.
To pollinate by hand, take a male flower and remove all its petals, press it against the centre of the female flower. Pollen can also be transferred using a fine paint brush, taking pollen from the male stamen and brushing it lightly over the female stigma.

Harvesting:
Cut cucumbers regularly from about twelve weeks after planting. The sides of the fruit should be parallel and about 12 to 15cm (6 to 8in) long. Cut them with a short stem and check the plant regularly for fruit. Regular cutting will produce more fruit.
Cucumbers generally don't store for very long unless pickled, so cut and use the fruit while fresh. The fruits are eaten raw, pickled or cooked.

Parthenocarpic vareities:
Parthenocarpic varieties produce fruit without the need for pollination. They are varieties are seedless, or nearly so and the fruit develops in the absence of fertilised seed. These varieties can produce seed if pollinated. Therefore, parthenocarpic varieties should be spatially isolated from other types of cucumbers to keep the fruit seedless.
Because parthenocarpic varieties do not produce large numbers of seed, even when pollinated, the cost of seed production is high, and the seed of these varieties is typically more expensive than seed of other varieties.
