Seedling
1-2 weeksEmerging cotyledons appear above soil; first true leaves develop within 7-10 days
Keep soil evenly moist but not waterlogged. Provide bright light and warmth (65-75°F). Thin seedlings if starting indoors.
Vegetative Growth
2-3 weeksCompact bushy plant develops with 4-6 true leaves; stems thicken and plant reaches 6-10 inches
Maintain consistent moisture. Weed regularly to reduce competition. Add mulch at 2 inches to conserve moisture and suppress weeds.
Flowering
1-2 weeksSmall white or pale purple flowers bloom along the stems; plant height reaches 12-18 inches
Maintain regular watering schedule. Do not overwater or over-fertilize, which can delay pod set. Avoid overhead watering.
Pod Development
2-3 weeksGreen pods emerge and grow 4-5 inches long; distinctive mottled red and cream coloring begins appearing
Water regularly but allow soil to dry slightly between waterings. Do not disturb plants when picking pods. Monitor for pests.
Harvest/Maturity
1-2 weeks for shell stage; 3+ weeks for full dryingPods become fully colored with deep red mottling on cream background; seeds inside become visible and hard
Harvest regularly for fresh shelled beans, or allow pods to dry on plant for dried beans. Plant will continue producing until frost.
