Flowering & Pod Development

6-8 months per flowering cycle

Small yellow or white flowers appear on panicles close to soil surface; flowers develop into green, ribbed seed pods (3-4 cm long)

Ensure consistent watering during flowering, maintain 60-80% humidity, provide potassium-rich fertilizer to support fruit development, thin excessive foliage if needed

Harvest Tips

Harvest seed pods 8-10 months after flowering when they turn from green to brown and become fully aromatic. Pick pods just before they fully mature to prevent shattering. Dry pods slowly in warm shade (80-100°F) for 10-15 days; they should crack easily when dry. Separate seeds from pods and store in airtight containers away from light and moisture for best flavor retention (up to 1 year). Best harvest window is during cool, dry season.
