Transplant Establishment
3-4 weeksSmall seedlings (4-6 weeks old) or sets planted in fall establish roots in cool soil
Plant in October-November in warm climates. Keep soil moist but not waterlogged. Mulch lightly to retain moisture and keep bulbs clean.
Vegetative Growth
8-12 weeksFoliage develops throughout winter and early spring; long leaves emerge as temperatures warm
Apply balanced fertilizer every 4-6 weeks. Monitor for frost and protect if hard freezes occur. Thin to proper spacing if crowded.
Bulb Initiation & Development
6-8 weeksAs day length increases to 12-14 hours (February-March), bulbs begin swelling at soil surface
Reduce nitrogen; increase potassium and phosphorus to promote bulb development. Mulch keeps soil even but allows bulb emergence. Keep consistent moisture.
Bulb Maturation
4-6 weeksBulbs enlarge rapidly with papery golden outer scales; necks thin and tops weaken
Taper watering as tops fall over (May-June). Stop fertilizing. Do not bend tops manually; allow natural collapse. Bulbs reach 3-4+ inches diameter.
Harvest & Curing
Harvest period: May-June in TexasFoliage browns and falls over; bulbs fully mature with dry papery skin
Harvest when 50-75% of tops have fallen over. Pull or dig carefully, allow to cure in warm, dry location (70°F+) for 2-3 weeks before storage.
