Troubleshooting
Alocasia Cuprea (Red Secret) problems — and how to fix them
Alocasia Cuprea (Red Secret) (Alocasia cuprea) 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 low humidity (or, less often, inconsistent watering or mineral-laden tap water). Raise humidity above 60% with a humidifier or pebble tray and switch to filtered or rainwater.
Yellowing leaves and root rot
Usually overwatering or poor drainage. Let the top inch or two dry between waterings, ensure a chunky free-draining mix and a pot with drainage holes, and cut back water in winter.
Leggy growth and dull colour
A sign of insufficient light. Move to a brighter spot with bright indirect light to restore the metallic copper-red sheen and compact form.
Spider mites
Common on stressed Alocasia, especially in dry air. Look for fine webbing and stippled leaves; rinse foliage, raise humidity and treat with insecticidal soap or neem oil.
Sudden leaf drop / winter dormancy
Often a natural semi-dormant rest, not death. Reduce watering, stop fertilising and keep the rhizome warm; new growth typically returns in spring.
Drooping leaves
Can signal either underwatering (dry, light pot) or overwatering and rotting roots (soggy, sour-smelling soil). Check the soil moisture before correcting, and confirm warmth above 18C.
