How to prune dragon fruit cactus

Late winter to early spring before new growth flushes, or after the fruiting season. Wear thick gloves. Cut overcrowded or unproductive stems back to the main trunk or a strong lateral using sterilized loppers. Shorten excessively long stems at a natural joint or node. Leave 4–6 strong main stems per trellis support. Allow cuts to callous for 48 hours before watering.

Annually; spot-remove damaged or diseased stems as needed. Dragon Fruit Cactus (Selenicereus undatus) grown indoors or in containers needs regular pruning to stay productive. Thin crowded, weak, or damaged stems annually. For fruiting plants, removing excess lateral branches improves airflow, reduces disease pressure, and concentrates energy into fewer, larger blooms and fruits.
