Troubleshooting
Colocasia Crown of Tonga problems — and how to fix them
Colocasia Crown of Tonga (Colocasia esculenta 'Crown of Tonga') 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.
Wilting and drying out
As a bog plant it cannot tolerate dry soil; even brief drought causes dramatic wilting and leaf collapse. Keep it constantly moist to wet, especially in heat and full sun.
Loss of purple colour
Too little light fades the signature burgundy tones to plain green. Give full to part sun, acclimating gradually, to keep the dark colouration vivid.
Cold damage and dieback
Frost and cold soil kill top growth and can rot tubers. Lift and store tubers, or heavily mulch in borderline zones, bringing it in before frost.
Spider mites in dry indoor air
Indoors, dry warm air invites mites and stippled leaves. Raise humidity, keep leaves clean, and treat early with insecticidal soap or neem.
