Conseils de culture
Dragon fruit requires sturdy concrete or wooden posts (1.5 m tall) with a circular support ring at the top for the heavy, sprawling stems.
Night-blooming flowers require cross-pollination; hand-pollinate in the evening for reliable fruit set, especially for self-incompatible red-flesh varieties.
Supplemental night lighting (low-wattage LED) during short days can induce off-season flowering and extend the harvest season.
