Germination & Seedling
1-2 weeksSeeds sprout and develop first true leaves; seedlings are delicate with cotyledons visible
Sow seeds only after soil reaches 65°F; keep soil warm and consistently moist. Thin to proper spacing once seedlings emerge.
Vegetative Growth
3-4 weeksVines develop multiple leaves and begin climbing; stems become woody and produce side shoots
Provide sturdy trellising or stakes for support. Water consistently and apply mulch to retain moisture. Avoid high-nitrogen fertilizer.
Flowering
2-3 weeksSmall, delicate white or pale pink flowers appear along the vines in clusters
Maintain consistent watering; flowers are sensitive to drought stress. Do not fertilize at this stage as it promotes foliage over flowers.
Pod Development & Early Maturity
3-4 weeksGreen pods with characteristic speckles develop and elongate; beans inside begin to form
Continue regular watering. Harvest young pods for fresh use or allow to mature for dry beans. Monitor for pests.
Full Maturity & Harvest
Ongoing, 2-3 months of harvest windowPods mature fully, speckles become more prominent; beans inside are cream-colored with brown speckles and are fully firm
Allow pods to dry on the vine for dry bean harvest. For fresh harvest, pick when pods are full but still tender. Vines may continue producing throughout season.

Harvest Tips
For fresh beans, harvest when pods are full but still tender and green, typically 65-75 days after planting. Pods will have firm beans inside but still be pliable. For dry beans, allow pods to remain on the vine until they turn brown and papery, then pick and shell. Harvest every 2-3 days during peak season to encourage continued production. Early morning harvesting when pods are cool reduces stress on plants.
