Troubleshooting
Black Turmeric problems — and how to fix them
Black Turmeric (Kaempferia parviflora) 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 in storage
The most common failure point: if the rhizomes are left in moist compost over winter, they quickly rot. After foliage dies back, remove the rhizomes, allow them to dry for 24–48 hours, and store in barely damp vermiculite or peat-free material at 10–15°C.
Failure to break dormancy
Rhizomes stored too cold (below 5°C) or too dry may fail to sprout in spring. Ensure storage temperatures remain above 10°C and introduce light watering in early spring to stimulate re-growth.
