Troubleshooting
Bent Masdevallia problems — and how to fix them
Bent Masdevallia (Masdevallia infracta) 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.
Crown and root rot
The leading killer. Caused by poor air circulation combined with excess moisture sitting on leaves or in the crown. Ensure airflow, avoid overhead watering, and use well-draining medium. Remove affected roots and treat with a fungicide such as hydrogen peroxide solution.
Heat stress and collapse
Masdevallia infracta suffers above 25°C. Leaves yellow and wilt rapidly in summer heat. Provide cooling via air conditioning, evaporative cooling, or move to a cooler basement or north-facing position. Night temperatures below 15°C are critical for bud initiation.
Spider mites
Low humidity encourages infestations, causing fine stippling on leaves. Inspect the undersides of leaves regularly. Treat with insecticidal soap or neem oil spray, and raise ambient humidity to deter recurrence.
