Seedling
7-10 daysCotyledons emerge and first true leaves develop. Plants are small and delicate.
Keep soil consistently moist but not waterlogged. Ensure adequate light to prevent leggy growth. Thin to proper spacing once plants have 2-3 true leaves.
Vegetative
3-4 weeksRapid leaf and stem growth; plants develop multiple branches with compound leaves.
Maintain even soil moisture and apply mulch to conserve water. Monitor for early pest damage. Support with stakes if plants become tall or lodging occurs.
Flowering
2-3 weeksSmall white, pink, or pale purple flowers appear in the leaf axils along the stem.
Ensure consistent watering during this critical period. Do not allow soil to dry out, as flower drop can occur. Continue to monitor for pests.
Pod Development
3-4 weeksFlowers transition to developing pods that grow plump and fuzzy with large green beans inside.
Increase watering to support pod filling. Pods typically remain hairy and contain 3-4 beans per pod. Monitor for spider mites and aphids.
Harvest
7-14 days window for prime harvestPods reach mature size with fully developed beans but before they harden and turn yellow.
Harvest when pods are bright green and full, typically 20-25 days after flowering. Pick early morning for best texture and flavor. Harvest regularly to encourage continued pod production.

Harvest Tips
Harvest pods when they are bright green, plump, and full-sized but before they begin to yellow (typically 100-105 days after planting). Pick in the early morning for best flavor and texture. Pods are ready when beans inside feel firm and well-developed. Gentle daily or every-other-day harvesting encourages continued flowering and production. For storage, blanch harvested pods in boiling salted water for 5 minutes, cool in ice water, and freeze in airtight containers for up to 8 months.
