Propagating Large Night-Blooming Cereus peruviana

Gene wanted to take cuttings from a 10-foot, multi-stemmed night-blooming Cereus peruviana after flowering. He asked where to cut (ground level, joints, etc.).

Greg advised selecting arms to remove and cutting 2–3 foot sections from the top of the plant. Sections too close to the base may not root. Let cut ends dry 3–4 weeks, then plant in well-draining cactus mix. Rooting takes a month or more.

Cutting Strategy

• Cut from upper stems, not base.
• 2–3 foot sections root best.
• Long callus period (3–4 weeks) is critical.
• Use pure cactus mix; no fertilizer until rooted.
