Best climate: This crop does well in warm areas where the temperature is usually between 24 and 32 degrees Celsius. It prefers places that receive around 1200 to 1800 millimetres of rain in a year. It can grow from near sea level up to about 1200 metres above sea level.

Plant spacing: Plant in rows about 100 centimetres apart, and leave about 100 centimetres between plants in the row. This gives each plant enough space for roots and canopy to spread.

Planting depth: Dig planting holes or furrows about 10 centimetres deep so the roots sit firmly in the soil but are not buried too deep.
