Seedling
2-3 weeksTiny seedlings emerge with two oval cotyledons and develop 2-4 true leaves
Keep soil moist; thin seedlings to proper spacing; provide consistent warmth (70-85°F)
Vegetative Growth
4-6 weeksPlant develops multiple sets of lance-shaped leaves along a main stem; reaches 2-4 feet tall depending on variety
Remove weeds regularly; monitor for pests; ensure adequate sunlight; no fertilizer needed if soil is rich
Flowering
3-4 weeksDelicate tubular flowers appear in the leaf axils, ranging from white to pale pink or purple depending on variety
Maintain consistent moisture; flowers are self-pollinating but attract beneficial insects; avoid excess nitrogen which delays flowering
Pod Development & Maturation
4-6 weeksFlowers fade and elongated seed pods form, gradually filling with seeds and turning brown/tan
Reduce watering slightly as pods mature; watch for ripeness; pods naturally split when fully mature to release seeds
Harvest Ready
At maturity, ready for harvestPods dry and turn golden-brown; seeds inside reach full size and hardness; plant may naturally dehisce (split open)
Harvest before pods fully split to prevent seed loss; seeds should be white and hard; dry completely before storage

Harvest Tips
Harvest when pods turn brown and begin to split naturally, typically 3-4 months after planting. Cut mature pods into a bucket or cloth before they fully dehisce to prevent seed loss. Dry harvested pods in the sun for 1-2 weeks, then gently crack open to release seeds. Spread seeds on a clean surface to dry completely (moisture content should be below 10%) before storing in airtight containers. Seeds are ready when they are hard and white with no moisture.
