Troubleshooting
Cambodian Sonerila problems — and how to fix them
Cambodian Sonerila (Sonerila cambodiana) 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.
Brown leaf tips and edges
Almost always a humidity or water-quality issue. Raise humidity above 70% and switch to rainwater or filtered water free of fluoride and chlorine.
Stem collapse and root rot
Caused by overwatering in dense or compacted media. Ensure the pot drains freely and allow the top layer of the mix to partially dry between waterings.
Leaf marking fades
Insufficient or excessively intense light can both reduce the contrast of leaf patterning. Bright, fully filtered light maintains the best colour; deep shade reduces silver markings.
