Seedling
2-3 weeksYoung plants emerge with cotyledons, developing first true leaves within 1-2 weeks
Keep soil consistently moist but not waterlogged. Thin seedlings to proper spacing. Provide full sun from emergence.
Vegetative
3-4 weeksBushy plants develop multiple stems and compound leaves, growing 12-24 inches tall
Maintain moderate watering. Apply mulch to conserve moisture and suppress weeds. No fertilizer needed due to nitrogen-fixing ability, but light feeding helps.
Flowering
2-3 weeksPurple or lavender flowers appear in clusters along stems, indicating pod development is beginning
Continue regular watering at soil level to avoid wetting flowers. This is a critical stage; maintain consistent moisture without flooding.
Pod Development & Fresh Harvest
3-4 weeksLong, slender green pods (4-8 inches) form and mature, ideal for harvesting as snap beans
Harvest pods frequently when young and tender to encourage continued production. Water steadily but allow soil surface to dry between waterings.
Seed Maturation & Dry Harvest
4-6 weeksPods dry on the plant, turning brown and papery as seeds inside mature to cream color with black eye spot
Reduce watering once pods begin drying. Leave pods on plant until completely dry and brittle. Harvest before heavy rains to prevent sprouting.

Harvest Tips
For snap beans: Harvest pods when 4-6 inches long and still tender, typically 60-70 days after planting. Pick frequently for continuous production. For dry seeds: Allow pods to brown completely on the plant (90-120 days), then shell and dry seeds further indoors for 2-3 weeks before storage. Store dry seeds in cool, dry conditions away from light.
