Cucumber 'Long White'

Cucumis sativus

Half-hardy Annual

Greenhouse type.

Cucumber 'Long White' is not just a novelty! The firm flesh is sweet and juicy, with a pleasant tang that will add flavour to your salads without a bitter after taste. The tender, white skins are so thin that they won't even need peeling. This attractive variety is a good cropper when trained against supports in the greenhouse. Height: 3m (9'). Spread: 45cm (18").

Greenhouse cucumbers must be grown in a warm, humid greenhouse with a minimum temperature of 15C (60F). Outdoor (Ridge) types are suitable for growing outside. Some varieties may be suited to indoor and outdoor cultivation.


Sow Cucumber seeds from early March to April for indoor cropping and for transplanting outdoors later on. Outdoor varieties may also be direct sown outdoors from May to June. Sow cucumber seed on their sides at a depth of 1cm (½") in 7.5cm (3") pots of free-draining, seed sowing compost. Place in a propagator or seal container inside a plastic bag at a temperature of 20C (68F) until germination which takes 7-10 days. Protect the emerging seedlings from direct sunlight to avoid scorching. Grow Cucumber plants on until they are large enough to be transplanted. Maintain a minimum temperature of 15c (60F) and keep the compost moist but not wet.


When cucumber plants are well grown, transplant them at a spacing of 2 plants per growbag or 45cm (18") apart in a warm, humid greenhouse. Outdoor varieties should be gradually acclimatised to outdoor conditions over 7-10 days before transplanting into warm, well drained, humus rich soil in full sun, with shelter from winds. Plant outdoor cucumbers in single rows at a distance of 90cm (36") apart. Water well after planting until cucumber plants are fully established.

Water cucumber plants regularly. Apply greenhouse shading as required and create a humid atmosphere by regularly spraying or damping down pathways.


Climbing greenhouse types will produce higher yields if allowed to climb. Train the main shoots onto 1.8m (6ft) high nets, canes or strings until they reach the top of their support and then pinch out the growing point. Pinch out sideshoots once fruit begins to develop, leaving two leaves after each fruit. Remove male flowers from greenhouse types.


Outdoor ridge types can be pinched out at the main stem after 7 leaves have formed to encourage sideshoots. Outdoor ridge types require pollination by insects - do not remove male flowers from these varieties.


When growing cucumbers, harvest regularly to encourage, long continuous production. Pick the fruits whilst young and tender before they show signs of producing seeds, as older fruits can become bitter. Harvesting cucumbers is best done early in the morning when temperatures remain cool.

  1. Too many male flowers

    By margaret Hughes 25-08-2016

    I had good germination with this plant and planted best ones in greenhouse. It flowered prolifically and despite removing as many male flowers I could it produced so many male flowers I coudlnt keep on top of it so the fruit on the whole were very bitter. What a disappointment because if all the fruit had been edible we would have had a bumper crop.

  2. Wow, wow, wow!

    By Elaine Mayes 05-08-2016

    I sowed 4 seeds, 3 of which were planted in pots (2 in a greenhouse, 1 outside), in Kent. The 4th was outside in a veg bed in London. The latter went crazy, sprawling all over the veg bed and has yielded over 20 beautifully formed, gorgeous juicy cucumbers. The plants, in pots, in Kent have yet to produce anything but there is a promise of several fruit brewing! I will definitely grow them again next year but not in pots-perhaps planted in the garden and trained along a fence....they seem to want to creep rather than climb. Good fun to grow, pretty yellow flowers before fruit developers.
