Bulb rot in wet soil
Cold, waterlogged ground rots the fleshy bulb. Plant in sharp drainage and keep dry over summer dormancy.
Weak, leaning spikes
Warmth or poor light produces floppy stems. Grow cool and bright; later-year spikes loosen naturally and may need discreet support.
Skin irritation from bulbs
Calcium oxalate crystals on the bulbs irritate skin. Wear gloves when planting or handling stored bulbs.
Reduced flowering after forcing
