Troubleshooting
Metallic Heliconia problems — and how to fix them
Metallic Heliconia (Heliconia metallica) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Brown leaf-edge scorch
Crispy brown margins develop rapidly in low humidity or direct sun; a common problem when grown indoors in heated rooms with dry air. Boost humidity to above 60%, move away from direct sunlight, and ensure the rootball is never allowed to dry out.
Mealybugs
White cottony clusters appear at leaf axils and along pseudostem bases; mealybugs weaken the plant by sucking sap and excreting honeydew that encourages sooty mould. Remove with a cotton bud dipped in rubbing alcohol, then treat with neem oil or insecticidal soap.
