How to Grow

Cultivation

Start plants in a heated greenhouse, or on a windowsill. Can be moved to an unheated greenhouse, or outdoors, once all risk of frost has passed. Plant out in rich soil with plenty of organic matter, water regularly, and feed every 10-14 days. Grow up supports to ensure good airflow. See cucumber cultivation for further advice

Propagation

Propagate by seed. See sowing vegetable seeds

Pruning

Pinch out the tip of the plant once it reaches the top of the support to encourage branching. Pick fruit regularly to encourage further production

Pests

May be susceptible to glasshouse whitefly and glasshouse red spider mite when grown under glass, or to slugs and snails when grown outdoors

Diseases

May be susceptible to cucumber mosaic virus and powdery mildews
