Myanmar Purple Ginger problems — and how to fix them
Myanmar Purple Ginger (Zingiber ottensii) 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.
Scale insects
Flat, brown or white waxy scales attach to stems and the undersides of leaves; scrape off manually, treat with horticultural oil or insecticidal soap, and repeat applications at two-week intervals to break the life cycle.
Rhizome rot over winter
In zone 8 or borderline zones, the rhizome is vulnerable to rotting in cold, wet conditions; apply a thick (15–20 cm) mulch of straw or bark after the first frost to insulate the rhizome, and ensure the soil drains freely.
