How to care for your Dragon Fruit

Everything you need to keep your Dragon Fruit healthy: watering, light, humidity, feeding, repotting and pruning.

Native to southern Mexico and Central America, *Hylocereus undatus* is a remarkable climbing cactus that has become globally recognized for its exotic and nutritious fruit, the Dragon Fruit or Pitaya. It grows as a sprawling or vining plant, producing long, fleshy, three-sided green stems that climb using aerial roots. The true spectacle of this plant unfolds at night, when it produces enormous, fragrant, white flowers, sometimes up to 30 cm (12 inches) in diameter, which open for a single night. If pollinated, these flowers develop into the iconic, scaly fruits, typically with bright pink or yellow skin and white or red pulp dotted with tiny black seeds. It requires a warm, humid climate and sturdy support to thrive.
