How to propagate this plant

  1. Use a stem cutting: make a clean cut, manage the milky sap, let the wound dry or callus, then root the piece in sharply draining mix. Air layering is a separate method, and no universal cutting length or rooting-hormone need is established.
  2. Start in spring or early summer in a warm, bright indirect indoor position with cactus or succulent mix that drains freely. Protect the cutting from prolonged wetness while roots form.
  3. Wear gloves and eye protection. Cut a firm, healthy stem with a clean sharp tool, let the latex stop and the wound dry, prepare clean well-drained mix, insert the base without burying foliage, and water lightly while checking for roots.

Check visible progress before moving the plant

Signs of roots or failure

A progressing cutting stays firm at the base rather than soft. Later, resistance to a gentle check and new growth indicate roots and establishment, but no rooting day or root-length threshold is established.

Treat a leaking or contaminated wound, soft or darkening base, mold, persistent shriveling or no root development as a reason to stop and inspect the medium and cutting.

Transfer the plant after roots have formed
