The common bean is the number-one grain legume that people in East and Southern Africa eat straight from the pot — as dry beans (a pulse) or as fresh green/snap pods. It is a cool-weather crop that hates heat: when days climb above 30 °C or nights stay above 20 °C it drops its flowers, so the planting date is chosen to bring flowering into cool weather. Unlike a cereal, the bean makes much of its own nitrogen from the air through nodules on its roots, so it needs little nitrogen fertiliser — mainly phosphorus, plus lime where the soil is sour. It comes in two habits — quick, self-supporting bush beans and higher-yielding climbing beans that need stakes — and its seed carries several of its own diseases, which is why clean, certified seed matters so much.

Growing common bean, stage by stage
Your bean season from soil to store — sweeten sour soil and start with clean seed, plant so the flowers open in cool weather, keep the crop weeded and evenly watered through its two thirsty windows (flowering and pod-fill), then dry the grain hard and seal it airtight against weevils.
- Get your field, soil and seed ready
- Plant and set a full stand
- Grow the frame — weed early, stake climbers
- Flowering — protect the flowers
- Fill the pods
- Harvest the dry grain (or last green pods)
- Dry hard and store weevil-proof
