Dieffenbachia (Dumb Cane) Propagation Without Cutting Cane: Air Layering

To get a second plant without severing the cane, use air layering—roots form on the stem before cutting.

Air Layering Steps

1. Choose site: 12–18″ below tip, on healthy stem.
2. Wound: Cut ⅓ through stem (V-notch) or remove 1″ bark ring.
3. Hormone: Apply rooting hormone to wound.
4. Wrap: Pack damp sphagnum moss around wound. Cover with plastic wrap, seal edges (tape/twine) airtight.
5. Wait: 4–8 weeks for roots to fill moss.
6. Sever & pot: Cut below rooted zone. Pot in well-draining mix.

Alternatives

• Division: If multiple stems in pot, separate at roots during repotting.
• Cane cuttings: Cut 2–3″ cane sections, lay horizontally on moist perlite, half-buried. Each node sprouts.

Air layering is safest for thick, woody Dieffenbachia stems. High success, no risk to parent.
