Troubleshooting
Alocasia Sumo problems — and how to fix them
Alocasia Sumo (Alocasia 'Sumo') 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.
Root rot from overwatering
Soggy, dense mix and cold conditions cause yellowing leaves and a mushy rhizome base. Use an airy mix, let the top dry between waterings, and ensure a drainage hole.
Spider mites in dry air
Low humidity invites fine webbing and stippled, dull leaves. Raise humidity, wipe leaves, and treat early with insecticidal soap or neem before infestation spreads.
Crispy brown leaf edges
Caused by low humidity, underwatering, or salt buildup from excess fertiliser. Increase humidity, keep moisture even, and flush the soil periodically.
Sudden dormancy
Cold, drought, or shock can make it drop leaves and go dormant. Keep the rhizome warm and lightly moist; new growth usually returns rather than the plant being dead.
