Galangal problems — and how to fix them
Galangal (Alpinia galanga) 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.
Cold damage and rhizome rot
Frost kills top growth and cold, wet soil rots the rhizomes. Keep above 10°C and lift or heavily mulch rhizomes in cool climates.
Brown, crispy leaf tips from dry air
Low humidity browns the leaf edges. Raise ambient humidity and keep soil evenly moist to keep foliage lush.
Slow or no growth in cool, dim conditions
It stalls in cold or low light. Provide warmth and bright filtered light through the growing season to drive growth.
Spider mites indoors
Dry overwintering indoors invites spider mites. Mist, raise humidity and inspect leaf undersides, treating webbing with insecticidal soap.

Most galangal issues are care-mismatch, not bad luck. Dial in the basics:
