Troubleshooting
Cassumunar Ginger problems — and how to fix them
Cassumunar Ginger (Zingiber montanum) 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.
Rhizome rot from cold-wet conditions
The most serious threat in temperate climates is leaving rhizomes in cold, wet soil over winter; if not hardy in your zone, lift rhizomes before the first frost, dry for a few days, and store in barely moist sand or vermiculite at 10–15°C.
Aphids on new shoots
Soft new growth in spring and early summer attracts aphid colonies, which distort emerging leaves and pseudostems; knock off colonies with a strong water jet or treat with insecticidal soap, taking care to cover growing tips.
