How to propagate Adenium obesum

For a true-to-type Adenium obesum clone, use a stem cutting. Air-layering, fresh seed and grafting are separate routes with different outcomes.

What plant material to use

Adenium can be propagated from leafy young branches, older leafless branches, larger branches by air-layering, fresh seed or grafting. Stem cuttings are the route that keeps a named cultivar true.

How to propagate this plant

  1. Use a stem cutting for a clone, air-layer a larger branch until roots are visible, or sow fresh seed in the warm season. Grafting is a separate route joining a scion to a selected rootstock.
  2. For leafy cuttings, do not let the fresh cut callus or dry: dip it in rooting hormone, use very well-draining medium, and keep the environment evenly damp, very warm and moderately illuminated. Older stems need less moisture and humidity.
  3. Take leafy or mature material early in the growing season, apply rooting hormone to the fresh base and insert it into very well-drained medium. For an air-layer, notch the branch, apply hormone, wrap the notch in damp sphagnum or coir, and sever below visible roots before potting.

Check visible progress before moving the plant

Signs of roots or failure

A successful air-layer has a visible root system through the wrap. Arizona Extension says fresh seed can germinate in damp soil in a matter of days under warm conditions, but this does not establish a cutting timetable.

A leafy cutting that dries or is allowed to callus contrary to the Arizona method, or a setup that stays cold and wet, falls outside the supported conditions. Cold wet soil raises root-rot risk.

Transfer the plant after roots have formed
