Dormancy
June-NovemberCorm rests underground through summer and early fall with no visible growth
Keep soil dry during this period. Store corms in cool, dry location if lifted. Mulch lightly in late fall to protect from temperature fluctuations.
Root Development
November-DecemberFine roots emerge from corm base in late fall as soil cools, establishing the root system before winter
Ensure good drainage to prevent root rot. Water lightly if winter precipitation is absent.
Sprouting & Growth
February-March (depending on zone)Grass-like green shoots and flower buds emerge through soil surface in early spring as temperatures warm
Provide adequate moisture as buds develop. Protect from heavy frost if possible. Remove any debris from around emerging shoots.
Post-Bloom & Dormancy Preparation
April-JuneFoliage remains green after flowers fade, photosynthesizing to replenish corm energy reserves for next season
Continue watering moderately while foliage is green. Allow foliage to die back naturally. Stop watering once leaves fully yellow and dry.
