Spiked Ginger Lily problems — and how to fix them
Spiked Ginger Lily (Hedychium spicatum) 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.
Aphid infestation on new growth
Soft new shoots in spring can attract dense colonies of aphids; blast off with a strong jet of water, introduce ladybird larvae, or treat with an insecticidal soap spray avoiding flower buds.
Poor flowering in cold summers
H. spicatum requires sustained warmth to initiate and develop flower spikes; in cold or overcast seasons, position in the warmest microclimate available or grow in a large container that can be brought under glass in late summer.
