Fruit Edible Annual Biennial

A reasonably compact, climbing, American heritage cultivar, producing stems to 1.8m (6ft) high and prolific quantities of sweet, flavourful cucumbers to 20cm (8in) long. It is well-suited to growing outdoors in the UK. It is a ridge variety, so named because of its warty skin. All ridge varieties need to be pollinated to produce fruit, so the male flowers should not be removed.

How to Grow

Cultivation

Grow in an acidic to neutral, moisture-retentive, well drained compost and a position in full sun, in a conservatory, greenhouse, or outdoors in summer in the UK. This is a ridge variety and needs both male and female flowers to set fruit. See cucumber cultivation

Propagation

Propagate by seed. See sowing vegetable seeds

Suggested planting locations and garden types

  • Patio and container plants
  • Edible fruit
  • Conservatory and greenhouse

Pruning

pinch out tips of leading stems once they have reached the top of thee trellis or growing support. Laterals should be pruned two leaves beyond where a fruit is developing to divert the plant's energy into the development of the fruit, rather than into the lateral's vegetative growth

Pests

May be susceptible to glasshouse whitefly

Diseases

May be susceptible to Cucumber mosaic virus and powdery mildews
