Troubleshooting
Dove Masdevallia problems — and how to fix them
Dove Masdevallia (Masdevallia peristeria) 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.
Failure to reflower after summer
M. peristeria blooms most reliably when it experiences a genuine cool, dry-ish rest period in autumn with night temperatures dropping to 6-10°C. Without this temperature differential, flowering stimulus is absent and scapes fail to initiate. Ensure the plant experiences naturally cooler autumn nights.
Overwatering in winter
Growth slows considerably in winter and the medium dries more slowly. Continuing a daily watering regime in winter leads to anaerobic root conditions and rot. Check moisture by feeling the medium rather than following a fixed schedule, and allow slightly more drying time between waterings.
Mealybugs in leaf bases
Mealybugs can colonise the tight leaf sheaths at the base of each growth, often going unnoticed until the infestation is established. Inspect monthly, especially at the growing point, and treat with a rubbing-alcohol-tipped cotton swab or systemic insecticide appropriate for orchids.
