Reichenbach's Masdevallia problems — and how to fix them
Reichenbach's Masdevallia (Masdevallia reichenbachiana) 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 flower from excess heat
This species requires consistent cool night temperatures (10–13°C in winter) and a 6–10°C day-night differential to initiate blooming. Warm indoor conditions year-round suppress flowering entirely. A cool greenhouse or unheated sunroom is usually required.
Leaf tip burn
Black or brown leaf tips indicate water quality issues or fertiliser salt accumulation. Switch to rainwater or reverse-osmosis water and flush the medium monthly with clean water.
Fungal crown rot
Water pooling in the crown or on leaves in still air causes Fusarium or Botrytis rot. Always water at the base or on the roots, not the crown, and run a fan continuously. Remove affected tissue and treat with a systemic fungicide.
