Germination & Seedling
7-10 daysSeeds sprout and first true leaves emerge; plant stands 2-3 inches tall
Keep soil warm (70-75°F) and consistently moist; thin seedlings to proper spacing once first true leaves appear
Vegetative Growth
3-4 weeksBush develops multiple stems and dense foliage; plant reaches 12-18 inches height
Maintain consistent moisture; apply mulch to retain soil moisture and regulate temperature; provide balanced fertilizer if soil is poor
Flowering
2-3 weeksSmall white or light purple flowers appear in clusters along stems; plant is at full height
Reduce nitrogen fertilizer to avoid excess foliage; maintain consistent watering; do not disturb plants during this critical stage
Pod Development & Maturation
4-6 weeksPods form and elongate, containing developing beans; pods gradually turn from green to brown as beans mature internally
Reduce watering frequency to encourage dry bean development; allow pods to remain on plant until fully mature and dry
Harvest & Curing
2-3 weeks curingPods become brittle, brown, and completely dry; seeds inside are hard and fully developed
Pull entire plants when majority of pods are dry and brown; cure indoors in a dry location for 2-3 weeks before shelling

Harvest Tips
Allow pods to mature fully on the plant until they are completely brown and brittle (approximately 100+ days after planting). Harvest plants when pods are dry and seeds rattle inside; pull entire plants and hang upside down in a dry location for 2-3 weeks to cure. Shell beans by hand or by placing dried pods in a bag and crushing gently. Store in airtight containers in a cool, dry place for up to 2 years.
