Troubleshooting
Collins' Heliconia problems — and how to fix them
Collins' Heliconia (Heliconia collinsiana) 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.
Rust thrips and scale insects
Thrips (Chaetanaphothrips orchidii) and soft scale insects colonise the developing inflorescence bracts and leaf undersides, causing silvering, distortion, and sticky honeydew deposits. Treat with systemic insecticide or spinosad at the first sign of damage.
Pseudostem rot in cold or waterlogged conditions
Any exposure to temperatures below 10 °C combined with wet soil rapidly causes decay of the fleshy pseudostems. Ensure good drainage, lift and store rhizomes in frost-prone climates, and never water cold dormant plants heavily.
