Seedling
2-3 weeksThin grass-like shoots emerge with 2-3 leaves, upright growth habit begins
Keep soil consistently moist but not saturated. Thin seedlings if overcrowded. Protect from birds if necessary.
Vegetative Growth
4-6 weeksPlant develops robust leaf structure, multiple tillers form, height reaches 2-4 feet depending on variety
Water regularly during dry spells. Apply balanced fertilizer mid-season if soil is poor. Provide wind protection if in exposed location.
Flowering & Head Formation
2-3 weeksPanicle (seed head) emerges from top of stem, darkens to black color, flowers open in succession
Reduce watering frequency. Monitor for bird predation. Do not fertilize at this stage to avoid promoting leaf growth over grain fill.
Grain Filling & Hardening
3-4 weeksSeed head becomes fully black and compact, seeds harden and develop full nutritional content
Water minimally; rely on rainfall. Allow stalks to cure in field if weather permits. Support tall varieties in windy areas.
Harvest & Maturity
Variable, 2-7 daysSeeds are fully mature, hard, and resistant to cracking; entire plant dries down
Test seed hardness by nail indent—seed should not dent. Harvest when head turns dark brown and stalks are brittle. Store in cool, dry location.

Harvest Tips
Harvest when seed head is fully black and seeds are hard (cannot dent with fingernail). Cut entire panicle by hand or use a sharp knife when stalks are dry. Alternatively, allow head to dry completely on plant, then strip seeds by hand or thresh mechanically. Dry grain further in open air for 1-2 weeks before storage. Store in breathable containers in cool (below 70°F) and dry (below 12% moisture) conditions.
