How to prune narrow rib cereus

Late spring or early summer. Make one clean cut across the column with a sterilised blade, wearing thick gloves. Allow both the parent stump and severed top to callous for a week before treating the top as a propagation cutting. The parent will typically produce offsets at the cut site.

As needed — no routine pruning required. Narrow Rib Cereus is a columnar cactus that needs minimal pruning indoors. It does not branch naturally in the way shrubs do. Remove damaged or diseased sections only, cutting cleanly with a sterilised saw or pruners. Size can be managed by removing a top section, which may reroot as a cutting.
