Rescuing Waterlogged Euphorbia: Cutting Above Rot

A 6-ft Euphorbia (cathedral cactus) in pot without drainage, bottom turning to gel, top still green: rescue requires cutting above rot with extreme safety precautions.

Euphorbia Hazard Warning

• Latex sap: Causes severe burns, blindness, anaphylaxis
• PPE mandatory: Nitrile gloves, goggles, face shield, long sleeves, apron
• Work outdoors: Ventilation essential
• First aid: Eye wash, running water, antihistamine, epinephrine if allergic

Rescue Procedure

1. Cut 10" above highest gel/rot
2. Catch sap in container; rinse cuts with water
3. Inspect cross-section: no brown/black spots
4. Recut if needed (sterilize each cut)
5. Callus 3+ weeks (longer than cactus)
6. Plant in dry cactus mix
7. No water 3 weeks; then minimal

Original Plant

Dead. Discard soil, pot, and base. Sap remains toxic in debris.

Alternative

If uncomfortable with hazard: discard entire plant. Not worth injury risk for a replaceable specimen.

Euphorbia rescue is for experienced handlers only. The toxicity is not exaggerated.
