Seedling
1-2 weeksSeed germinates and cotyledons emerge; first true leaves appear within 7-10 days.
Ensure consistent soil moisture and warmth (60-70°F minimum). Protect from heavy rain and physical disturbance. Thin seedlings if overcrowded.
Vegetative
4-6 weeksPlant develops compound leaves and strengthens stems; bushy growth (bush varieties) or vine elongation (pole varieties) occurs.
Provide consistent moisture and light fertilization. Monitor for early pest activity. Support pole varieties with stakes or trellises. Maintain even watering.
Flowering
2-3 weeksSmall white or cream-colored flowers form in clusters along the stems.
Maintain steady watering without overwatering; inconsistent water stresses flowering. Avoid heavy nitrogen fertilization, which promotes foliage over flowers. Support structures should be secure.
Pod Development & Maturation
4-6 weeksFlowers fade and pods form; pods gradually fill with developing beans and transition from green to mature (tan/cream-colored).
Water moderately; reduce watering as pods mature to concentrate flavors and hasten drying. Watch for pod-feeding insects. Pods are ready for harvest when fully mature and dry.
Harvest & Drying
1-2 weeksPods brown and dry on the plant; beans inside rattle when shaken. Plant may senesce and leaves drop.
Allow pods to dry completely on plant if weather permits. If rain threatens, harvest mature pods and continue drying indoors in a warm, dry location. Shell beans once completely dry.

-
Increase humidity with regular misting; spray with water to dislodge; apply neem oil or insecticidal soap if severe.
-
Ensure good air circulation; avoid wetting foliage; remove affected leaves; apply sulfur dust or copper fungicide if needed; plant disease-resistant varieties.

Harvest Tips
Allow pods to mature fully and dry on the plant until they are tan or cream-colored and rattle when shaken (usually 100+ days after planting). Harvest pods when brittle and dry. If rainy weather threatens, harvest mature pods and finish drying indoors in a warm, airy space. Shell beans by hand or with a mechanical sheller, and store in an airtight container in a cool, dry place. Haricot Blanc beans store for 1+ years when properly dried and stored.
