Dormancy
3-4 months (winter storage)Corm is stored dry in cool conditions with papery outer layer intact
Store at 60-65°F in dark, well-ventilated location. Check occasionally for sprouting or mold.
Sprouting & Root Development
2-3 weeksCorm develops roots and first shoot emerges from the top; visible growth above soil within 2 weeks
Keep soil lightly moist. Ensure good drainage to prevent rot. Provide cool temps initially (50-60°F) for root establishment.
Vegetative Growth
3-4 weeksSword-shaped leaves emerge and elongate; plant grows 12-24 inches tall with multiple leaves along the stem
Water regularly, maintain consistent moisture. Support with stakes if growing in windy areas. Fertilize every 2-3 weeks with balanced fertilizer.
Bud Formation & Flowering
3-4 weeksFlower spike emerges from leaf axil; buds form along spike opening sequentially from bottom to top over 2+ weeks
Increase watering during flowering. Stake taller varieties. Deadhead spent flowers to encourage upper florets. Cut spikes in early morning when lower buds just open for arrangements.
Post-Flowering & Dormancy Prep
2-3 weeksFlowers fade and drop; foliage begins yellowing and dying back as plant stores energy in corm
Continue watering and fertilizing to build up corm strength. Once foliage dies back completely and is brown, stop watering. Lift corms in cool zones and store.
