Green's Ginger Lily problems — and how to fix them
Green's Ginger Lily (Hedychium greenii) 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.
Glasshouse red spider mite
Tiny mites colonise the undersides of leaves in warm, dry conditions under glass, causing pale mottling and fine webbing; raise humidity and treat with predatory mites or insecticidal soap.
Rhizome rot in winter
Overwatering or failure to reduce irrigation during dormancy allows cold, wet soil to rot rhizomes; lift and store frost-free or apply a deep mulch and cut back watering sharply in autumn.
