Troubleshooting
Colocasia Fontanesii problems — and how to fix them
Colocasia Fontanesii (Colocasia esculenta 'Fontanesii') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Brown, crispy leaf edges
Almost always underwatering or low humidity on this water-loving plant. Keep the soil constantly moist and humidity high.
Yellowing or dormancy
Cold temperatures below about 15°C trigger leaf loss and dormancy. Keep warm; in cool climates store the tuber dry over winter.
Spider mites in dry air
Indoor dryness invites stippling on the broad leaves. Raise humidity, keep soil wet, and treat with insecticidal soap or neem.
Faded stem colour
Insufficient light dulls the prized dark purple-black stems. Move to brighter light to deepen the colouration.
