Strobel's Masdevallia problems — and how to fix them
Strobel's Masdevallia (Masdevallia strobelii) 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.
Shrivelled leaves from drying out
Unlike many orchids, Masdevallia strobelii has no pseudobulbs to store water. Even brief drying of the roots causes leaves to shrivel and wrinkle. Mounted plants need daily watering; potted plants should never be allowed to dry fully.
Fungal leaf spotting
The combination of high humidity and poor air circulation creates ideal conditions for Botrytis and Cercospora. Run a fan continuously and water only in the morning so foliage dries before nightfall.
Failure to reflower
Insufficient light or excessively warm night temperatures suppress blooming. Ensure nights drop to 10–15°C and increase light levels gradually. Switch to a high-phosphorus fertiliser in late summer to trigger bloom initiation.
