Mexican Butterwort problems — and how to fix them
Mexican Butterwort (Pinguicula moranensis) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Fungus gnat infestation
Ironically, the very gnats the plant traps can multiply in the moist substrate around the plant. Reduce tray water levels between refills, allow the top layer of soil to dry slightly, and use yellow sticky traps nearby.
Rotting in winter
Continuing tray watering after the plant switches to its succulent rosette is the leading cause of root and crown rot. Transition to very infrequent light misting as soon as the compact winter form appears, typically in late autumn.
