Seedling
2-3 weeksCotyledons emerge, followed by first true leaves. Plant is low-growing and tender.
Thin seedlings to proper spacing once they reach 2-3 inches tall. Maintain consistent moisture. Protect from cool temperatures below 60°F.
Vegetative
3-4 weeksPlant develops compound leaves and establishes bushy or semi-vining growth habit. Strong root system forms.
Provide light fertilizer if soil is poor. Support semi-vining types with stakes or trellises. Keep weeds controlled.
Flowering
2-3 weeksSmall cream or pink flowers appear in leaf axils. Plant becomes increasingly bushy.
Reduce nitrogen fertilizer to avoid excessive foliage at expense of flowers. Maintain moderate, consistent moisture. Avoid overhead watering to reduce disease.
Pod Development & Fruiting
3-4 weeksFlowers set into flat pods containing 2-4 small beans. Pods mature from light green to tan or brown.
Continue consistent watering during this critical stage. Harvest pods regularly to encourage continued production. Monitor for pests.
Harvest & Maturity
Ongoing, 3-6 weeksPods are ready for shell beans when full-sized and slightly dry, or can harvest for green beans earlier.
Pick regularly to extend harvest window. For dry beans, leave pods on plant until completely dry and brown.
