Rolfe's Masdevallia problems — and how to fix them
Rolfe's Masdevallia (Masdevallia rolfeana) 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.
Heat stress and leaf dehydration
Temperatures above 24°C cause rapid dehydration in thin-leaved plants. Leaves become soft, wrinkled, and may yellow. Move to a cooler position immediately; set pot in a tray of water briefly to re-hydrate the root zone, then restore normal watering rhythm.
Botrytis bud blast
In stagnant humid air, grey mould attacks developing buds and open flowers. Increase air circulation with a small fan, remove infected material promptly, and consider a copper-based fungicide spray as a preventive in cool, damp winters.
Root rot from degraded medium
Bark breaks down in 9–15 months, becoming anaerobic and retaining excess water. Inspect roots annually and repot as soon as the medium smells sour or squeezes wet. Trim any black or mushy roots before repotting into fresh coarse bark.
