Long-Horned Ginger Lily problems — and how to fix them
Long-Horned Ginger Lily (Hedychium longicornutum) 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.
Root desiccation
As an epiphyte, exposed roots dry out rapidly in low humidity or if watering is missed; mount on cork bark with a sphagnum moss pad around the roots and mist twice daily in warm weather.
Mealybugs in leaf axils
Mealybugs colonise the tight leaf axils and root mass, causing stunted growth and sticky honeydew; treat with a cotton bud dipped in methylated spirits or apply a systemic insecticide if infestations are heavy.
