Germination & Seedling
10-14 daysSeeds sprout and cotyledons emerge. Young seedlings develop first true leaves.
Maintain consistent moisture without waterlogging. Protect from heavy rain. Thin seedlings to proper spacing.
Vegetative Growth
30-45 daysPlant develops bushy foliage with compound leaves. Lateral branches form. No flowers yet.
Ensure adequate spacing for air circulation. Monitor for pests and diseases. Light, balanced fertilization if needed.
Flowering
20-30 daysSmall white, purple, or pink flowers appear in clusters at leaf axils and branch tips.
Maintain consistent moisture during this critical stage. Avoid high nitrogen fertilizer. Ensure good sunlight. Bee activity aids pollination.
Pod Development & Maturation
25-35 daysFlowers develop into small cylindrical pods (2-4 inches long) containing 4-8 seeds. Pods gradually dry and turn brown.
Reduce watering as pods mature. Monitor for pod-boring insects. Avoid overhead watering to prevent fungal issues.
Harvest & Drying
Harvest periodPods are fully dry, brittle, and rattle when shaken. Seeds inside are hard and fully mature.
Harvest when 80-90% of pods are dry. Thresh to separate seeds. Dry seeds further to 10-12% moisture for storage.
