Cutting and Rerooting a 7-Foot Columnar Cactus/Euphorbia

Alan's 7-foot single-stem plant bent at the top with three new growths forming. He asked if he could cut and replant the top.

Critical Warning

It may be a Euphorbia (milky, burning sap), not a cactus. Test: cut a small piece—white latex = Euphorbia.

Procedure (Both)

1. Cut desired section (2–3 ft from top).
2. Let cut end callous 3–4 weeks.
3. Plant in well-draining cactus mix.
4. Water thoroughly once, then only when dry.
5. New growth signals success.

Wear gloves/eye protection if Euphorbia.
