Cultivation

The species are sensitive to inappropriate cultural conditions and will show signs of stress by leaf spotting or dropping. They can generally be grown in pots with sphagnum or seedling grade wood chips although a few species produce descending inflorescences and are best accommodated in baskets. In both cases the rhizome should remain at the surface of the medium in order to prevent rot. Most of these plants are from high altitude cloud forests and require very cool conditions and abundant moisture throughout the year. They cannot tolerate dryness, low humidity, or excessive temperatures and the plants are very easy to kill. They will simply drop all their leaves and suddenly collapse if allowed to dry completely or are exposed to high temperatures. Many members of this genus from very high altitude cloud forests defy cultivation. Most of the species from this genus are considered less difficult in cultivation than plants from the genus ''Dracula'', and some of them are very easy to cultivate and have a 'weedy' habit such as Veitch's masdevallia, but the majority of these species are usually very difficult to maintain in cultivation unless the plants can be kept cool and moist all the time. Low humidity conditions or watering the plants with a water source which contains high levels of dissolved salts will result in the leaves yellowing and rapidly dying from the tips back to the rhizome. The plants should be provided with rain water or distilled water or a very pure water source. The medium should always remain moist as the plants do not have any significant storage structures like most orchids.
