Propagating Night-Blooming Cereus: How to Start New Plants from Cuttings

That towering, night-blooming cactus you've nurtured for 20 years—likely a Cereus peruvianus or similar species—can absolutely be propagated from cuttings. These dramatic plants, pollinated by moths and bats, produce huge, fragrant white flowers that open at dusk and fade by morning. If yours has outgrown its indoor space, taking cuttings is a great way to preserve its legacy while keeping the parent plant manageable.

How to Root Cereus Cuttings

Select a healthy stem segment 12–18 inches long. Use a clean, sharp knife to make a clean cut at a joint. Let the cutting callus over in a dry, shaded spot for 1–2 weeks—this step is critical to prevent rot. Once the cut end is firm and dry, plant it 2–3 inches deep in a well-draining cactus mix. Water sparingly until roots establish, which can take several weeks to a few months. Provide bright, indirect light and warmth.

The parent plant will often branch at the cut point, becoming fuller. Your new plant will be genetically identical and should bloom once mature.
