Disocactus is a genus of cacti found in Central America, the Caribbean, and northern South America. Do not confuse it with Discocactus, a different genus.
Species grow in tropical regions either on trees as epiphytes or on rocks as lithophytes. They have two different growth habits. Species such as D. phyllanthoides have stems that are round at the base but then become flattened and leaf-like. Other species, such as D. flagelliformis, have round stems throughout their length.
Many cultivated plants known as Epiphyllums result from crosses between species of Disocactus (rather than Epiphyllum) and other genera in the Hylocereeae tribe.
Growing Conditions
Light: Like all cacti, give these cacti lots of direct sunlight, especially during the summer.
Water: During the growing period, the plants need frequent watering. Water relatively abundantly so the soil is completely soaked, but let it dry between waterings. Keep relatively dry in winter or when night temperatures remain below 50°F (10°C).
Soil: Well-drained soil is preferred, and most Disocactus perform well in soil with some organic matter.
Propagation
Disocactus can be propagated from seeds and cuttings.
Grower's Tips
Disocactus should be grown in rich but still well-draining soil. Water and fertilize regularly, as both are essential for good growth and flowering. Disocactus dislikes extreme heat and cold, so they are best grown in a greenhouse during the depth of winter and the heat of summer in hot, dry climates. They also prefer partial shade to full sun and like a little extra humidity. They flower in spring and summer, and flower color varies from white, yellow, red, or purple, depending on the species.
