=== Soil and water ===

As a pitaya crop, it is reasonable to begin with a sharply drained soil and a site where irrigation can be controlled; this is a genus-level cultivation inference rather than a species-specific soil prescription.<sup>[[#cite_note-2|[2]]]</sup> Keep the root zone from remaining saturated, provide organic matter where the native soil is poor, and use a sturdy trellis before the stems become difficult to train. Water deeply during active growth, then allow excess water to drain freely. Reduce irrigation during cool or dull periods when the plant is using water more slowly.
