Troubleshooting
Pink Hidden Ginger problems — and how to fix them
Pink Hidden Ginger (Curcuma rubescens) 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.
Over-watering in dormancy
The most common cause of failure is continuing to water the plant heavily after it enters dormancy. Allow the soil to become quite dry in winter; the rhizomes are naturally dormant and rot easily in wet conditions.
Failure to re-emerge in spring
If rhizomes were kept too dry or too cold over winter, they may fail to sprout. Store rhizomes at 15-18°C and water moderately in late winter to stimulate re-emergence.
Spider mite in dry conditions
Low indoor humidity encourages spider mite. Increase humidity with a tray of water and gravel beneath the pot, and apply neem oil at the first sign of infestation.
Root rot in compacted soil
Poor drainage causes the fleshy rhizomes to rot. Always use a free-draining mix and ensure the pot has adequate drainage holes.
Short display season indoors
The flower heads have a relatively brief display period of 3-6 weeks. Grow multiple rhizomes to extend the overall flowering season.
