Troubleshooting
Red Stem Ginger Lily problems — and how to fix them
Red Stem Ginger Lily (Hedychium greenii) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Rhizome rot
The main risk in cold, wet winters; lift rhizomes before hard frosts in USDA zones below 8 and store dry.
Aphids on new growth
Inspect emerging shoots regularly in spring; treat early with insecticidal soap to prevent colony establishment.
Faded flower colour
Occurs in very deep shade; move to brighter conditions to maximise the vibrant orange-red hue.
Sparse flowering
Insufficient pot size or nutrition; repot into a larger container and increase feeding during the growing season.
Frost damage
Stems are frost-tender; mulch heavily outdoors in borderline climates or move containers under cover before first frost.
