Troubleshooting
Colocasia Black Coral problems — and how to fix them
Colocasia Black Coral (Colocasia esculenta 'Black Coral') 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.
Leaves greening up
Insufficient light fades the near-black color; move to full sun to maintain the dark pigment.
Crispy leaf margins
Low humidity or drying soil scorches edges; keep the root zone wet and humidity high.
Spider mites
Hot, dry air encourages mites on the undersides; rinse foliage and treat with insecticidal soap, raising humidity.
Slow spring start
Cold soil delays sprouting from dormant tubers; wait for warmth (18°C+) before expecting new shoots and avoid overwatering bare corms.
