Seedling
7-10 daysCotyledons emerge and first true leaves appear. Plant is 2-4 inches tall with compound leaves developing.
Keep soil consistently moist but not waterlogged. Protect from strong winds. Thin seedlings to proper spacing if direct seeded.
Vegetative
20-30 daysPlant grows bushy with multiple stems and increasingly compound trifoliate leaves. Height reaches 10-16 inches.
Maintain consistent moisture, especially during dry spells. Apply mulch to retain moisture and suppress weeds. Do not fertilize heavily as it promotes excessive leaf growth at expense of pod production.
Flowering
10-15 daysSmall white or pale purple flowers appear in clusters along the stems. Plant reaches full 16-24 inch height.
Continue regular watering; flowering is water-sensitive. Avoid high-nitrogen fertilizers. Do not disturb plants when wet to prevent rust diseases.
Pod Development & Maturation
30-40 daysFlowers set into long, slender green pods containing developing beans. Pods gradually turn yellow-brown as seeds mature inside.
Reduce watering gradually to concentrate flavors and aid pod drying. Monitor for pests. Allow pods to stay on plant as they mature and dry.
Harvest & Curing
5-10 days before curing beginsPods turn brown and papery; seeds inside are hard and fully mature. Plant senesces.
Harvest when pods are completely brown and rattle when shaken. Pull entire plant or pick individual pods. Cure indoors in a warm, dry location for 2-3 weeks before shelling.

Harvest Tips
Allow pods to remain on the plant until they are completely brown and papery, typically 85-100 days after planting. Harvest when pods rattle when shaken, indicating seeds are fully dry. Pull the entire plant or pick individual dry pods. Cure harvested pods indoors in a warm (70-80°F), dry location for 2-3 weeks to ensure complete moisture removal. Shell by hand or use a mechanical thresher. Store dried beans in airtight containers in a cool, dark place for up to one year.
