How to grow cucumber on a terrace?

Cucumber is a fast-growing creeper ideal for terrace trellises. Sow seeds February–March or June–July in 15-litre grow bags. Best varieties: Pusa Uday, Malini hybrid. Provide a 4–5-foot trellis. Water daily — cucumbers are 95% water. Feed with balanced NPK fortnightly. Powdery mildew is common in humid months; use neem oil spray preventively. First harvest in 45–55 days.
