APOROCACTUS

Habitat: Mexico.
Description: this epiphytic genus is commonly referred to as ‘rat’s tail cactus’ because of the long, slender stems of the plants. They produce purplish red flowers on older parts of the stems from late spring into summer. In nature, they are found on steep cliffs, even on rocky ones, and on the branches of trees in the forest canopy.
Soil: fertile mix, pH of 6.5.
Location: bright; they can be grown in direct sunlight until May but filtered light during the summer is preferable. They won’t flower unless they receive enough light during the rest period.
Temperature: tender to half-hardy, it can withstand occasional light frosts (in this case no water should be given), so grow it outdoors only in mild areas. However, a minimum winter temperature of 5 or 6°C (41-43°F) is recommended.
Water: plenty of water from spring to autumn and little during the winter; keep the soil always moist.
Cultivation tips: propagate from cuttings during the summer; apply fertilizer in early spring. It is suitable for growing in hanging baskets. They must be allowed to have a period of rest. They’re particularly susceptible to mealy bugs. It can be grafted on Cereus or Opuntia.
Main species: A. flagelliformis (similar to flagriformis), grows in the foggy mountain rainforests. A. conzattii; A. martianus.
