Troubleshooting
Wide-Bract Heliconia problems — and how to fix them
Wide-Bract Heliconia (Heliconia platystachys) 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.
Failure to flower
In cultivation outside the tropics, H. platystachys often fails to bloom without a deliberate dry rest period. Withhold irrigation for 4–6 weeks in late autumn, maintain warmth above 15°C (59°F), and resume watering in spring to stimulate bract initiation.
Thrips damage to bracts
Thrips cause silvery scarring and distortion of the broad, colourful bracts, which significantly reduces ornamental and cut-flower value. Inspect new bract sheaths regularly and treat infestations early with spinosad or neem oil; maintain strong air movement around plants.
