Troubleshooting
Scarlet Ginger Lily problems — and how to fix them
Scarlet Ginger Lily (Hedychium coccineum) 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.
Rhizome rot
Caused by waterlogging, especially in winter dormancy; ensure pots have adequate drainage and reduce watering as soon as foliage fades in autumn.
Spider mites
Tetranychus urticae thrives in hot, dry conditions; increase ambient humidity, mist foliage and treat severe infestations with a horticultural soap or neem-oil spray.
Failure to flower
Most commonly caused by insufficient warmth or light during the growing season, or by dividing rhizomes too frequently before they have time to bulk up.
