Seedling
7-10 daysCotyledons emerge and first true leaves appear. Plant is low and compact
Keep soil evenly moist but not waterlogged. Thin seedlings to proper spacing once second true leaf appears. Protect from direct wind if possible
Vegetative Growth
30-40 daysBush plant develops multiple stems and extensive foliage. Bushy, compact growth habit with deep green leaves
Water when top inch of soil is dry. Apply mulch to retain moisture and regulate soil temperature. Avoid overhead watering to prevent fungal issues
Flowering
20-30 daysSmall white or light purple flowers appear at leaf axils and branch tips. Flowers are typical legume structure
Maintain consistent moisture during flowering. Do not over-fertilize with nitrogen as this reduces flowering. Monitor for pests
Pod Development
25-35 daysSmall green pods form after flower fertilization. Pods gradually elongate and mature to full size
Continue regular watering. Reduce frequency as pods mature. Do not disturb plants when wet to prevent rust disease spread
Maturity & Harvest
10-15 daysPods dry down to brown/tan color. Seeds inside rattle when pod is shaken. Plant foliage begins to senesce
Allow pods to dry completely on plant before harvesting. Stop watering 2 weeks before harvest. Harvest when pods are completely dry
Common Pests
-
Hand-pick adults and egg clusters. Use row covers for young plants. Apply neem oil if infestation is heavy. Encourage natural predators
-
Spray with water to dislodge. Increase humidity. Apply neem oil or insecticidal soap. Avoid over-fertilizing with nitrogen
-
Avoid overhead watering. Ensure good air circulation. Remove infected leaves. Apply sulfur-based fungicide if severe
-
Harvest and dry beans quickly. Store in sealed containers with diatomaceous earth. Use vacuum sealing for long-term storage
