Care and Culture Card
See basic growing conditions and care information below.
Mount Domingoa on small slabs without moisture-retaining material at the roots or grow them in small pots using a fine seedling-grade mixture. If grown in pots, the pots should be hung up above the benches to ensure maximum air movement. They are specialized twig epiphytes in nature. Provide bright light and warm temperatures. Water frequently during active growth and only as maintenance watering once the growths have matured.
