Troubleshooting
Powdery Spiral Ginger problems — and how to fix them
Powdery Spiral Ginger (Costus pulverulentus) 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.
Leaf browning at edges
Typically low humidity or draughts. Move away from air conditioning vents and increase ambient moisture.
Slow or no flowering
Needs bright light and regular fertilising. Ensure it receives at least four to six hours of bright indirect light daily.
Scale insects
Check cane junctions and undersides of leaves. Remove manually with a damp cloth and treat with neem oil.
Root rot
Ensure freely draining soil and pots. Water only when the top layer is dry.
Leggy, weak canes
Sign of inadequate light. Move to a brighter location or supplement with a grow light.
