Lesser Shell Ginger problems — and how to fix them
Lesser Shell Ginger (Alpinia conchigera) 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.
Spider mites
Low humidity in heated glasshouses encourages spider mite outbreaks; look for fine webbing and silvery stippling on the undersides of leaves and treat promptly with neem oil or a suitable miticide.
Rhizome rot
Sitting in waterlogged compost causes rapid rhizome rot, especially in cooler months when growth slows; ensure containers have adequate drainage holes and reduce watering frequency in winter.
