Hairy Ginger Lily problems — and how to fix them
Hairy Ginger Lily (Hedychium villosum) 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
Under glass in warm, dry conditions, spider mites cause pale stippling on leaves and may produce fine webbing; increase humidity and use predatory mites (Phytoseiulus persimilis) as biological control.
Poor or no flowering
Insufficient light or overly congested rhizomes are the most common causes of flowering failure; move to a brighter position and divide congested clumps every 3–4 years in spring.
