🌱 Introduction and history

Bushu (Cucumis zambianus), also known as the African Wild Cucumber or Zambian Cucumber, is an annual climbing plant in the Cucurbitaceae family — relatives of gourds, melons, and cultivated cucumbers. Indigenous to Southern Africa, it grows naturally in South Africa, Zambia, and Zimbabwe, thriving in grasslands and along fences. Traditionally gathered from the wild, Bushu has been valued not only for its unique spiky green fruits but also for its medicinal and cultural uses.

💊 Medicinal Benefits

In traditional African medicine, Bushu has been used for:

• Digestive support – Leaf infusions may relieve indigestion and mild stomach discomfort.
• Anti-inflammatory properties – Compounds such as cucurbitacins are believed to reduce inflammation.
• Mild detoxification – Sometimes used in small amounts as a gentle cleansing herb.

⚠️ Note: Overconsumption can cause nausea or stomach upset. Always use in moderation.

📅 When to Plant in South Africa

Plant Bushu seeds in spring after the last frost, ideally from September to November. In warmer coastal areas, sowing can be extended to early summer. Seeds germinate in 7–14 days, and plants mature for harvest in 60–90 days.

🏡 Where to Plant

Bushu prefers open ground where it can sprawl or climb on supports like trellises or fences. Ideal for vegetable gardens, sunny borders, or edges of cultivated fields.

🌞 Soil, Water & Sunlight Requirements

✅ Soil – Well-draining, fertile soil enriched with compost or aged manure.
✅ Sunlight – Full sun (6–8 hours daily) for best flowering and fruiting.
✅ Water – Keep soil evenly moist; avoid waterlogging to prevent root rot.
✅ Fertilize – Apply a balanced organic fertilizer monthly during active growth.
✅ Spacing – 30–45 cm apart for bush growth; 60 cm if trellising.
✅ Seeds germinate – 7–14 days in warm soil.
✅ Transplanting – Move seedlings after 2–3 weeks when they have at least 2–3 true leaves.
✅ Maturity height – Vines can trail 1–2 m; with support, they can climb higher.
