Feeding

Feed with a balanced organic fertiliser monthly to maintain good productivity.

Spacing

Single Plants: 2.00m (6' 6") each way (minimum)
Rows: 2.00m (6' 6") with 2.00m (6' 6") row gap (minimum)

Sow and Plant

Dragon fruit is propagated by rooting cuttings, so start with a purchased plant. Plant outdoors in a fertile spot that is easy to water. Planting can be done year-round in tropical climates. Young plants need regular water their first year. They are generally less drought tolerant compared to other cacti. Dragon fruit cacti grow 3 to 6 m (10 to 20 feet) tall and up to 3 m (10 feet) wide. In containers, plant one plant per 35 cm (14-inch) wide pot. Dragon fruit makes a very fast-growing houseplant for warm, sunny windows.

Notes

Native to Mexico and Central America, dragon fruit cactus often starts producing in its third year after planting, and healthy plants may live for fifteen years or more. Most growers tie young plants to a secure post so they grow into a top-heavy cluster that resembles a single-trunked tree. While not as prickly as some cactus, dragon fruits do have spines, so wear thick gloves when handling this plant. When transplanting, it helps to wrap the plant in paper to reduce injury to you and the cactus. The large white flowers of dragon fruit cactus are edible, and open only at night. Depending on cultivar, the inside flesh of dragon fruits may be white, yellow or red. In tropical climates where dragon fruits grow as long-lived perennials, mature plants need support and regular pruning. To maintain plant vigor, trim out old or broken branches when you see them, two or three times a year.

Harvesting

Dragon fruits are ready to harvest when the fruits pull free with a gentle twist. Refrigerate after harvesting to keep the fruits from softening.
