Troubleshooting
Red Tower Ginger problems — and how to fix them
Red Tower Ginger (Costus barbatus) 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 leaf tips
Caused by low humidity or fluoride in tap water; raise humidity and switch to rainwater or filtered water.
Scale insects
Check the undersides of leaves and stem nodes; remove manually and treat with horticultural oil.
Leggy growth
Insufficient light causes stems to stretch; move to a brighter position or supplement with a grow light in winter.
Root rot
Excess moisture with poor drainage; repot into free-draining mix and reduce watering frequency.
No bracts developing
Typically linked to insufficient warmth or light; ensure minimum 20°C and a brightly lit position.
