dormancy cycles on Alocasia Polly
Quick answer
If your Alocasia Polly has dormancy cycles, the most likely cause is: Alocasia amazonica 'Polly' enters seasonal dormancy triggered by reduced photoperiod (less than 10 hours of light) and temperature drops below 65°F (18°C). As a tropical understory plant native to Southeast Asian rainforests, it lacks cold tolerance and responds to unfavorable conditions by redirecting energy from leaf maintenance to underground corm preservation. The corm acts as a survival organ, storing starches that sustain the plant through 8-12 week dormant periods.
Start here:
- 1. Reduce watering frequency by 50% when growth slows—allow soil to dry to 50% depth between waterings
- 2. Maintain humidity at 50-60% minimum to prevent corm desiccation even when leaves yellow

How to reverse dormancy cycles on Alocasia Polly
- 1
Reduce watering frequency by 50% when growth slows—allow soil to dry to 50% depth between waterings
- 2
Maintain humidity at 50-60% minimum to prevent corm desiccation even when leaves yellow
- 3
Do NOT cut yellowing leaves prematurely—allow plant to reabsorb nutrients (chlorophyll, nitrogen) first
- 4
When all leaves have yellowed, store corm in original pot with barely moist soil in dark, cool (60-65°F) location
- 5
Resume normal watering and light in March when day length increases—new growth emerges from corm center in 2-4 weeks
Keep dormancy cycles off this Alocasia Polly
Maintain consistent temperatures above 68°F (20°C) year-round; provide 12-14 hours of bright indirect light daily using grow lights in winter; maintain 60%+ humidity to reduce stress; avoid fertilizing October through February when dormancy risk is highest.
