Troubleshooting
Cockleshell Orchid problems — and how to fix them
Cockleshell Orchid (Prosthechea cochleata) 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.
Limp, hollow pseudobulbs
Usually overwatering and rotting roots, or occasionally severe underwatering. Check roots: firm and silver-green are healthy, mushy and brown are rotten. Repot into fresh bark and water only when the mix nears dry.
No flowers
Most often too little light or no seasonal dip. Move to brighter filtered light and allow slightly cooler nights; well-grown plants bloom for much of the year on the same spike, so do not cut green spikes off.
Black or sunken leaf spots
Fungal or bacterial spotting from stagnant, overly damp air. Improve airflow, avoid water sitting in leaf crowns overnight, and remove affected tissue with a sterile blade.
Wrinkled, dehydrated leaves with healthy roots
Signals the mix is drying too fast or has broken down and no longer holds water. Repot into fresh medium-grade bark and increase humidity around the plant.
