Dormancy & Planting
1-2 weeks to emergenceCorms are stored dormant and planted in spring after last frost. Early shoots emerge from pointed end.
Plant corms 4-6 weeks before last expected frost. Ensure excellent drainage. Use fresh, disease-free corms.
Vegetative Growth
3-4 weeksSword-like leaves emerge and elongate. Plant grows taller and develops strong root system and additional cormlets around base.
Water consistently. Support tall varieties with stakes or cages as they approach 24+ inches. Fertilize weekly with balanced fertilizer.
Bud Formation & Flowering
2-3 weeksFlower spike emerges from center of plant with buds developing along the stem. White florets begin opening from bottom to top.
Stake plants for support if necessary. Maintain consistent moisture. Cut spent flower spikes on one-third of plants for succession blooming.
Peak Bloom & Cutting
2-4 weeks depending on heatMultiple florets are open simultaneously in pure white ruffled display. Spikes are ideal for cutting at this stage.
Cut spikes in early morning when flowers are firm. Cut at least one-third of stem below ground. Harvest regularly to encourage more blooms.
Senescence & Corm Maturation
3-4 weeksFlowers fade and wilt. Foliage begins to yellow. Below ground, corms enlarge and new cormlets develop for next season.
Stop deadheading; allow seed pods to develop to direct energy to corms. Reduce watering gradually. Fertilize with low-nitrogen, high-potassium formula.
