Troubleshooting
Prism-fruit Prosthechea problems — and how to fix them
Prism-fruit Prosthechea (Prosthechea prismatocarpa) 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.
Pseudobulb rot at base
Water collecting at the base of pseudobulbs in low-airflow conditions promotes bacterial soft rot.
Spider mites
Low humidity and warm indoor environments encourage spider mite outbreaks on the large leaf surfaces.
Oversize container
Planting in too large a pot retains excess moisture around roots, predisposing the plant to rot.
Leaf spotting
Fungal leaf spots develop when water sits on leaves overnight or humidity is very high without air movement.
Failure to re-bloom
Insufficient light or a very warm, uniform temperature without seasonal cues inhibits annual flowering.
