Troubleshooting
Curcuma Alismatifolia problems — and how to fix them
Curcuma Alismatifolia (Curcuma alismatifolia) 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 in dormancy
Cold, wet soil over winter rots the dormant tubers. Once leaves die back, keep the rhizomes nearly dry and above about 13-15°C; store lifted tubers in dry, frost-free conditions in cold regions.
Failure to re-sprout
Rhizomes started too cold or kept too wet may not break dormancy. Wait for warm temperatures (around 18°C+) in spring before watering to trigger reliable new growth.
Few flowers in low light
Insufficient light produces leafy plants with weak stems and sparse bracts. Give the brightest position possible with some direct sun to encourage strong, colourful flower spikes.
Spider mites and scale
Warm, dry indoor air can bring spider mites or scale onto the foliage. Inspect leaves regularly during growth and treat early with insecticidal soap or by wiping pests off.
