Cucumis sativus 'Suyo Long'
Suyo Long Cucumber
Chinese heirloom cultivar; the species C. sativus is native to South Asia (India)Overview
Cucumis sativus 'Suyo Long' is Suyo Long cucumber (Chinese long cucumber), a vigorous climbing annual vine 72-96 inches (180-240 cm / 6-8 feet) on a trellis. Long slender dark green fruit 15-18 inches (38-45 cm) with prominent longitudinal ridges and a curved serpentine shape when grown on the ground — straighter when trellised (gravity pulls them straight). Thin edible skin with low cucurbitacin content (a burpless type — reduced bitterness and digestive discomfort). Bright yellow trumpet-shaped monoecious flowers. Large deeply lobed heart-shaped leaves. In the gourd family (Cucurbitaceae). Chinese heirloom. Open-pollinated: seed can be saved. Monoecious: requires bee pollination. The fruit is longer and more slender than standard American slicing types ('Straight Eight,' 'Marketmore'). Heat-tolerant: continues fruiting in summer heat when other cucumber cultivars decline. Cucumber beetles (Diabrotica, Acalymma) transmit bacterial wilt (Erwinia tracheiphila) — the primary pest concern. Consistent moisture — drought causes bitter fruit. Direct-sow after last frost when soil reaches 65°F (18°C). Not deer-resistant. Non-toxic (edible crop). Full sun. Tender annual. Growth rate is fast.

Care & Maintenance
Care Guide
Full sun (6+ hours). Rich moist soil pH 6.0-7.0. Trellis for straight fruit (curved on the ground). Consistent moisture (bitter in drought). Requires bee pollination. Heat-tolerant. Cucumber beetles transmit bacterial wilt. Harvest at 12-15 inches (30-38 cm). Non-toxic. Tender annual.Pruning
Train vines to a trellis. Remove lower leaves touching soil. Harvest regularly at 12-15 inches (30-38 cm) — overripe fruit becomes seedy and bitter. No other pruning needed.Pruning Schedule
