Dormancy/Chilling
12-16 weeksBulbs rest underground after being planted in autumn, requiring 12-16 weeks of cold temperatures (below 45°F) to break dormancy.
Plant bulbs in October-November. Ensure proper drainage and protect from waterlogging. Store or plant in cool location for consistent chill period.
Emergence
2-3 weeksNarrow, grass-like green shoots emerge from soil as temperatures warm in late winter to early spring.
Monitor for moisture balance. Protect emerging shoots from late frosts if needed. Ensure adequate drainage to prevent rot.
Vegetative Growth
2-3 weeksFoliage develops fully, with leaves elongating and thickening. Flower buds begin to form at the shoot tips.
Water moderately if spring is dry. Apply light feeding with low-nitrogen, bulb-specific fertilizer. Remove any damaged foliage.
Flowering
2-4 weeksSmall star-shaped flowers in rose-pink tones appear on thin stems, typically 6-12 inches tall. Blooms last 2-3 weeks.
Deadhead spent flowers to encourage additional blooms. Keep soil consistently moist but well-drained. Avoid disturbing plants.
Post-Flowering & Dormancy
4-6 weeksFoliage yellows and withers as the plant returns energy to the bulb for next season's growth.
Allow foliage to die back naturally before removing. Reduce watering as leaves fade. Do not remove foliage prematurely; it feeds the bulb.
