Mejia's Masdevallia problems — and how to fix them
Mejia's Masdevallia (Masdevallia mejiana) 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.
Overheating in summer
Cool-intermediate to cool temperatures are critical. Above 25°C causes wilting and decline. Position in the coolest part of the home or use a fan-cooled cabinet.
Root rot
Occurs when medium becomes compacted and anaerobic. Repot regularly into fresh open bark and ensure the pot has multiple drainage holes.
Botrytis grey mould
Forms in stagnant humid air. A continuously running low-speed fan is the primary prevention.
Bud blast
Emerging buds collapse if temperature rises suddenly or humidity falls sharply. Keep conditions stable through flowering.
Dehydration stress
Leaves wrinkle when roots are dry. Increase watering frequency and check that roots are alive and functional; brown papery roots cannot absorb water.
