How to Air Layer Your Plants
In order to air layer, wrap a wounded part of your stem in moist sphagnum moss.
- The stem should be wounded below the node using an upward 1-inch slash. Hormone rooting compound can be applied to the surface of the wound if you choose.
- Wedge a small piece of wood into the cut so that it does not close
- Wrap the moss around the cut and secure it with string or twine.
- Cover the moss in aluminum foil first then plastic wrap to conserve the moisture.
Most plants with root in a couple weeks to a month. Once there are roots, remove the material and pot the plant as you normally would.
Potential Problems Air Layering
