- Seedlings
- Not typically required if soil is fertile.
- Growing
- Low nitrogen, moderate phosphorus and potassium for pod development. Avoid high nitrogen fertilizers.
- Flowering and fruiting
- Moderate phosphorus and potassium to support pod set and development.
- How often
- Rarely: beans fix their own nitrogen; feed once or twice in the season only if the soil is poor.
- Note
- Legumes fix their own nitrogen, so excessive nitrogen fertilization can reduce yield.
