Propagating Crown of Thorns (Euphorbia milii) from Cuttings

A reader in Switzerland asked where to cut a Crown of Thorns for cuttings: at the branch base or where leaves start.

Cutting Guidance

• Prune at any point on a stem; new growth emerges just below the cut.
• For propagation, use tip cuttings under 6 inches long.
• Let cuttings air-dry (callus) 24 hours.
• Insert 1 inch deep into a small pot with porous mix.
• Keep mix slightly damp; provide warmth and bright light.
