Propagating Totem Pole Cactus (Lophocereus schottii monstrose) from Arms

How to Remove and Root a Totem Pole Cactus Arm

The totem pole cactus (Lophocereus schottii monstrose form) readily propagates from stem cuttings. Here's how to safely remove an arm and establish a new plant.

Cutting the Arm

1. Tool: Clean, sharp pruning saw or hacksaw for thick arms.
2. Mark orientation: Before cutting, mark the south-facing side of the arm with a permanent marker (dot or line). This is critical—replanting with the wrong side facing south causes fatal sunburn.
3. Cut location: Cut at the joint where the arm meets the main stem for cleanest appearance and best healing.

Callusing and Planting

1. Callus: Place cutting in dry, shaded, well-ventilated area for minimum 2 weeks (longer in humid/cool conditions). Cut end must be completely dry and hard.
2. Soil: Well-draining cactus mix in a pot with drainage holes.
3. Plant: Insert callused end 2–3 inches deep. Stabilize with stakes or rocks if needed.
4. Orientation: Ensure the marked south side faces south.
5. Water: Do not water for first 2–3 weeks. Then water sparingly—only when soil is bone dry.

Parent Plant Care

The main stem needs no special treatment; the cut will callus naturally. No sealants or "band-aids" required.

Timeline

Rooting takes 4–8 weeks. New growth (small knobby stems) indicates success. Gradually increase water and light as plant establishes.
