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.
Troubleshooting
Though dragon fruits need regular water, they can suffer from root rot when kept too damp. Insects and diseases are not common, but animal pests are famous for harvesting almost-ripe fruits. In Australia fruit fly are a pest of dragon fruit, make sure to take appropriate control measures in areas where they are present. It is important to dispose of any infected fruit and fruit has fallen to the ground by placing them in a sealed plastic bag in the sun for at least 7 days to kill the eggs and larvae. Do not compost fruit as this will lead to the fruit fly completing their life cycle and lead to the problem recurring.
