Hemisphere Torch Ginger (Etlingera hemisphaerica) 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.
Scale insects
Armoured or soft scales encrust pseudostems and leaf midribs; scrape off manually, then apply a systemic insecticide or repeated neem oil treatments every 7–10 days.
Cold damage and draughts
Temperatures below 15°C cause rapid yellowing and die-back; even brief cold draughts near doors or vents can cause irreversible damage to the foliage. Maintain minimum 18°C.
