Troubleshooting
Callus Slipper Orchid problems — and how to fix them
Callus Slipper Orchid (Paphiopedilum callosum) 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.
Crown and base rot
Water trapped in the crown or a permanently soggy mix rots these pseudobulb-less plants. Water at the base, keep the crown dry, and maintain airflow.
Brown leaf tips
Salt or mineral accumulation from hard water or over-feeding. Use rain or distilled water and flush the mix to wash out salts.
Pale, scorched leaves
Too much light. Move to a shadier spot; this mottled-leaf species wants low to medium light and no direct sun.
Failure to flower
Commonly insufficient light or lack of a temperature drop. Provide bright shade and a slight night-time cooling to initiate spikes.
