Their need for a cool, damp environment makes them an excellent choice for cool, coastal climates. Masdevallias can be kept in light intensities up to 2,500 foot- candles if the growing area can be kept cool. Plants grow well under four-tube fluorescent fixtures and can be summered outside in shade.
Cool evenings help reduce heat stress during the day.
Roots should be allowed to become just dry before watering again if drainage is adequate, constantly moist roots are fine. In the greenhouse or enclosed growing area, humidity can be increased by misting or wetting down the floors, while evaporative coolers help raise humidity and lower temperatures. If plants are summered outdoors, automatic misters under the benches are recommended. If weather is dull, applications once a month are sufficient. Plants must be repotted frequently, every one to two years, to keep the potting mix from decomposing.
